What is a Crawler Tractor and How Does It Work


A crawler tractor is a tractor that travels on continuous tracks instead of conventional wheels. The track system distributes the machine’s weight across a larger contact area, which can improve traction and flotation on soft, wet, muddy or uneven ground.

Agricultural crawler tractors are commonly used for land preparation, rotary tillage, plowing, leveling and other operations that require stable pulling performance. Compared with wheeled tractors, they generally provide better traction in difficult field conditions but have lower travel speeds and higher undercarriage maintenance requirements.

This guide explains how a crawler tractor works, its main components, common agricultural uses, benefits, limitations and the factors to consider when choosing between tracks and wheels.


Key Takeaways

  • A crawler tractor travels on continuous tracks rather than conventional wheels.

  • The track system distributes machine weight over a larger contact area and can improve traction and flotation on soft or wet ground.

  • Agricultural crawler tractors are commonly used for plowing, rotary tillage, land preparation, leveling and work in rice paddies.

  • Compared with wheeled tractors, crawler tractors usually travel more slowly and require more undercarriage maintenance.

  • Engine power, track width, hydraulic capacity, implement compatibility and field conditions should all be considered when choosing a crawler tractor.

  • Regular inspection of tracks, rollers, sprockets, fluids and hydraulic components helps maintain reliable performance.


What Is a Crawler Tractor?

A crawler tractor, also called a tracked tractor, is a power machine that moves on two continuous tracks instead of pneumatic tires. The tracks rotate around drive sprockets, rollers and idlers, creating a larger contact area between the tractor and the ground.

This design can improve traction and reduce the risk of excessive wheel slip or sinking in soft, muddy and uneven fields. However, actual performance depends on machine weight, track dimensions, soil moisture, operating speed and the attached implement.

Agricultural crawler tractors are commonly used where pulling performance and field access are more important than road speed.


Crawler Tractor Basics

Main Components of a Crawler Tractor

Component Main Function
Engine Supplies power for movement, hydraulic systems and attached implements
Transmission Transfers and controls power delivered to the tracks
Tracks Support the machine and provide ground contact and traction
Drive sprockets Transfer power from the drivetrain to the tracks
Track rollers Support machine weight and guide track movement
Idlers Guide the tracks and help maintain correct tension
Steering system Controls the speed or power delivered to each track
Hydraulic system Operates mounted or trailed agricultural implements
Hitch or attachment system Connects the tractor to tillage and land-preparation equipment
Operator controls Allow the operator to control speed, direction and implements


Key Characteristics

Crawler tractors are generally selected for the following characteristics:

  • Large ground-contact area

  • Strong low-speed traction

  • Reduced wheel slip in difficult conditions

  • Stable pulling performance

  • Compatibility with heavy tillage implements

  • Ability to operate in some wet, soft or uneven fields

These characteristics do not mean that a crawler tractor is always better than a wheeled tractor. Wheeled models may be more suitable when higher road speed, frequent field transfers and lower undercarriage maintenance are priorities.


Agricultural Crawler Tractors vs Construction Crawlers

Agricultural crawler tractors and construction crawlers both use continuous tracks, but they are designed for different types of work.

Feature Agricultural Crawler Tractor Construction Crawler
Main purpose Tillage, land preparation and agricultural field operations Earthmoving, grading and construction work
Typical attachments Rotary tiller, plow, harrow, seeder and ditcher Blade, ripper, bucket and construction implements
Hydraulic system Configured for agricultural implements Configured for earthmoving attachments
Field requirements Crop fields, paddies, orchards and farmland Construction sites, roads and land-clearing areas

For farming applications, buyers should choose a model designed for agricultural implements and field operations rather than relying only on the general term “crawler tractor.”

How Does a Crawler Tractor Work?

A crawler tractor converts engine power into controlled movement through its transmission, final drives, drive sprockets and continuous tracks. The two tracks can be controlled at different speeds, allowing the tractor to move forward, reverse and turn while maintaining traction on challenging ground.

The basic working process is:

  1. The engine generates mechanical power.

  2. The transmission adjusts speed and torque.

  3. Final drives transfer power to the drive sprockets.

  4. The sprockets pull the continuous tracks around the undercarriage.

  5. Rollers and idlers guide and support the tracks.

  6. The steering system changes the relative speed of the two tracks.

  7. The hydraulic system powers compatible agricultural implements.、



Engine and Transmission

Most agricultural crawler tractors use diesel engines because they provide the low-speed torque required for tillage and pulling operations.

The transmission controls how engine power reaches the undercarriage. Depending on the model, the tractor may use a mechanical, power-shift or hydrostatic transmission.

A suitable transmission allows the operator to:

  • Adjust working speed

  • Maintain steady pulling power

  • Match speed to soil and implement conditions

  • Reverse or change direction

  • Control the tractor during low-speed field operations

Engine power should be matched to the tractor’s weight, hydraulic requirements and attached implements. Horsepower alone does not determine actual field performance.


Drive Sprockets and Final Drives

The final drives transmit power from the transmission to the drive sprockets. The sprocket teeth engage with the track links and pull the track around the undercarriage.

This system converts rotational power into forward or reverse movement. Proper sprocket condition and track tension are important because excessive wear may cause vibration, inefficient power transfer or track disengagement.


Continuous Track System

Each continuous track moves around a set of sprockets, rollers and idlers. As the tractor advances, the lower section of the track remains in contact with the ground while the upper section returns around the undercarriage.

The larger contact area can provide:

  • Better flotation on some soft soils

  • Reduced wheel slip

  • Stable low-speed traction

  • Improved pulling performance

  • More consistent movement over uneven ground

Actual ground pressure depends on machine weight, track width, track length, attached equipment, soil moisture and operating conditions.


Steering System

A crawler tractor turns by changing the speed or power delivered to each track. To turn left, the system slows the left track or increases the speed of the right track. The opposite action turns the machine to the right.

Depending on the tractor design, steering may be controlled through:

  • Steering clutches and brakes

  • Differential steering

  • Hydrostatic steering

  • Independent hydraulic track drives

Some machines can make very tight turns, but aggressive turning may disturb the soil and increase track wear. Operators should use smooth steering inputs, especially on firm surfaces.


Hydraulic System and Agricultural Implements

The hydraulic system supplies controlled power to mounted or trailed implements. It may operate lifting mechanisms, cylinders, depth controls and other attachment functions.

Common compatible implements include:

  • Rotary tillers

  • Plows

  • Harrows

  • Seeders

  • Ditchers

  • Leveling equipment

  • Mowers

Before connecting an implement, confirm the required hydraulic flow, pressure, hitch type, power requirements and tractor compatibility.


How the Systems Work Together

During field operation, the engine supplies power to both the drivetrain and hydraulic system. The transmission controls travel speed, while the tracks convert power into ground movement. The operator adjusts steering, speed and implement position according to soil conditions and the required task.

Efficient operation depends on balancing engine load, travel speed, traction and implement depth. Excessive speed or an unsuitable implement may increase fuel consumption, track slip, component wear and soil disturbance.


Crawler Tractor vs Wheeled Tractor


Crawler and wheeled tractors are designed for different operating conditions. A crawler tractor uses continuous tracks to increase ground contact and traction. A wheeled tractor uses pneumatic tires to provide faster travel and easier movement between fields.

Neither type is better in every situation. The right choice depends on soil moisture, field layout, required pulling power, road travel and maintenance priorities.

Comparison Factor Crawler Tractor Wheeled Tractor
Ground contact Larger contact area Smaller contact area
Traction Often better on soft or wet ground Effective on on dry and firm ground
Flotation Lower risk of sinking in some soft soils Depends on tire width, pressure and load
Travel speed Generally lower Generally higher
Road movement Less suitable for frequent road travel More convenient between fields
Turning Can provide a tight turning radius Usually causes less surface disturbance when turning
Maintenance Track system requires regular inspection Tire and axle systems are generally simpler
Initial cost Often higher for similar power levels Often lower
Suitable fields Wet, soft, muddy or uneven fields Dry, firm and accessible fields
Common applications Heavy tillage, paddies and difficult terrain General farming, transport and lighter field work

When Should You Choose a Crawler Tractor?

A crawler tractor may be suitable when:

  • Fields are frequently wet, muddy or soft

  • Wheel slip limits pulling performance

  • Heavy tillage implements are used

  • Operations require stable low-speed traction

  • The tractor works mainly inside fields

  • Rice paddies or uneven farmland are common

  • Reducing the risk of deep rutting is important

Track width and tractor weight still need to match the soil conditions. A crawler tractor can also sink or disturb soil if the machine is too heavy or operated improperly.


When Should You Choose a Wheeled Tractor?

A wheeled tractor may be more suitable when:

  • Fields are dry and firm

  • The tractor frequently travels on roads

  • Higher transport speed is required

  • Maintenance simplicity is a priority

  • The work includes hauling and general farm transport

  • Fields are widely separated

  • Heavy drawbar traction is not the main requirement

Wide or flotation tires can also improve the performance of wheeled tractors on softer ground.


Which Tractor Is Better for Farming?

Choose a crawler tractor when field traction and flotation are more important than road speed. Choose a wheeled tractor when versatility, transport efficiency and simpler maintenance are the main priorities.

For farms with both wet and dry conditions, compare the machines using:

  • Soil moisture during the working season

  • Required implement power

  • Average travel distance between fields

  • Tractor and implement weight

  • Track or tire ground-contact area

  • Expected annual working hours

  • Local spare-parts and service availability

The final decision should be based on actual field conditions rather than assuming that tracks or wheels are always better.


Benefits and Limitations of Crawler Tractors

Crawler tractors provide strong traction and stable pulling performance in difficult field conditions. However, they also travel more slowly and require more undercarriage maintenance than many wheeled tractors.

Understanding both the advantages and limitations helps farmers decide whether a tracked tractor fits their land, implements and daily operating requirements.


Benefits of Crawler Tractors

Improved Traction

Continuous tracks create a larger contact area with the ground. This can reduce slip and improve power transfer during plowing, rotary tillage and other high-draft operations.

The improvement is most noticeable on:

  • Wet fields

  • Soft soil

  • Muddy ground

  • Uneven farmland

  • Fields requiring heavy tillage

Actual traction depends on track design, machine weight, soil condition and the attached implement.


Better Flotation on Soft Ground

Tracks distribute machine weight across a larger area than conventional narrow tires. This can reduce the risk of deep sinking and help the tractor continue working in some soft-field conditions.

Flotation performance depends on:

  • Track width and contact length

  • Total tractor weight

  • Implement weight

  • Soil moisture

  • Grain or material load

  • Operating technique

Tracks do not eliminate the risk of sinking. Extremely wet or weak soil can still prevent safe operation.


Stable Low-Speed Pulling Performance

Crawler tractors are designed for operations where pulling force is more important than travel speed. They can maintain stable movement while operating plows, rotary tillers, harrows and land-leveling equipment.

This makes them suitable for repetitive field operations performed at controlled speeds.


Reduced Wheel Slip

Lower slip can help convert more engine power into useful field work. It may also reduce unnecessary soil disturbance caused by spinning wheels.

However, poor track tension, worn components or an incorrectly matched implement can still reduce operating efficiency.


Adaptability to Challenging Fields

Crawler tractors can be considered for rice paddies, soft farmland, reclaimed land and some uneven fields. Their low-speed control and continuous ground contact can improve movement where conventional tires struggle to maintain traction.

Slope suitability must always be confirmed using the manufacturer’s operating limits. Tracks do not make every slope safe.


Limitations of Crawler Tractors

Lower Travel Speed

Crawler tractors generally travel more slowly than wheeled tractors, especially on roads and firm surfaces. This may reduce efficiency when fields are widely separated.

Long-distance movement may require suitable transport equipment.


Higher Undercarriage Maintenance

The track system contains wear components such as:

  • Track links

  • Pins and bushings

  • Rollers

  • Idlers

  • Drive sprockets

  • Track-tension components

These parts require regular inspection, cleaning, lubrication and adjustment. Operation on abrasive or hard surfaces may increase wear.


Greater Turning Disturbance

Tight or pivot turns can disturb the soil surface and increase track wear. Operators should use wider, smoother turns whenever field space allows.

This is particularly important in planted fields, orchards and areas where surface damage must be limited.


Higher Purchase and Repair Costs

A crawler tractor may have a higher initial price than a wheeled tractor with similar engine power. Track-system repairs can also be more expensive than replacing or repairing conventional tires.

Buyers should compare total ownership costs rather than purchase price alone.


Less Convenient Road Operation

Tracks may generate more vibration and wear when used on hard roads. Some machines may also be subject to local road-use restrictions.

Buyers should consider how often the tractor must travel between fields before choosing a tracked model.


Advantages and Limitations at a Glance

Advantages Limitations
Strong traction in difficult soil Lower road speed
Better flotation on some soft fields Higher undercarriage maintenance
Stable low-speed pulling More surface disturbance during tight turns
Reduced slip during heavy tillage Higher purchase or repair cost
Suitable for some wet and uneven fields Less convenient for frequent road travel

A crawler tractor is most valuable when its traction and flotation benefits solve a real field problem. If most work takes place on firm ground with frequent road travel, a wheeled tractor may be more economical.


Common Agricultural Uses of Crawler Tractors

Crawler Tractors in Agriculture

Crawler tractors are mainly used for agricultural operations that require stable low-speed traction, strong pulling performance or improved flotation on soft ground. Their actual suitability depends on tractor configuration, soil conditions and implement compatibility.


Rice Field Preparation

Crawler tractors are commonly used in rice paddies because their tracks can provide better flotation than conventional narrow tires.

Typical rice-field tasks include:

  • Rotary tillage

  • Puddling

  • Field leveling

  • Ditching

  • Seedbed preparation

  • Pulling compatible planting equipment

Track width, ground clearance and machine weight should match the paddy conditions. Extremely soft or deeply flooded fields may still require specialized equipment.


Plowing and Primary Tillage

Plowing and deep soil preparation require consistent pulling force. A crawler tractor can reduce slip and maintain a steady working speed when operating suitable plows or subsoilers.

Before selecting a tractor, compare:

  • Required implement horsepower

  • Draft load

  • Working depth

  • Soil type

  • Field moisture

  • Hitch compatibility

Using an oversized implement can overload the engine, transmission and undercarriage.


Rotary Tillage and Seedbed Preparation

Crawler tractors can power rotary tillers used to break up soil, mix crop residue and prepare planting beds. Their stable low-speed movement helps maintain a more consistent tillage depth.

The tractor’s engine power, PTO specifications, hydraulic capacity and working speed must match the rotary tiller.


Land Leveling

Level fields can improve water distribution, drainage and planting consistency. Crawler tractors may be fitted with compatible leveling equipment for:

  • Paddy-field leveling

  • Seedbed preparation

  • Surface correction

  • Irrigation preparation

  • Reclaimed farmland improvement

The required tractor size depends on soil volume, blade width, working depth and field conditions.


Seeding and Planting Support

With compatible attachments, crawler tractors may support seeding and planting operations in fields where wheeled tractors experience excessive slip.

Possible implements include:

  • Seed drills

  • Planters

  • Fertilizer applicators

  • Bed-forming equipment

  • Planting-support equipment

Confirm PTO, hydraulic and hitch compatibility before connecting any implement.


Ditching and Drainage Work

Crawler tractors can operate ditchers and other compatible tools used to create drainage channels or irrigation paths.

Stable traction is useful where the tractor must maintain a controlled direction and working depth. However, operators should avoid unstable edges, deep channels and slopes outside the manufacturer’s operating limits.


Orchard and Vineyard Management

Compact crawler tractors may be used between orchard or vineyard rows where the ground is soft, uneven or sloped.

Common attachments include:

  • Mowers

  • Rotary tillers

  • Sprayers

  • Mulchers

  • Cultivators

Important selection factors include tractor width, turning radius, overall height, track disturbance and clearance around trees or vines.


Wet and Soft Field Operations

Crawler tractors can be considered for farmland where conventional wheeled tractors frequently experience sinking or excessive slip.

Suitable tasks may include:

  • Land preparation after rainfall

  • Working in reclaimed fields

  • Maintaining drainage areas

  • Tillage in high-moisture soil

  • Supporting seasonal paddy operations

Operators should still assess soil-bearing capacity before entering the field. Tracks reduce ground pressure in some configurations, but they do not prevent every machine from becoming stuck.


Agricultural Applications at a Glance

Application Common Implement Main Selection Requirement
Rice-field preparation Rotary tiller or puddler Flotation and ground clearance
Plowing Moldboard or disc plow Drawbar power and traction
Seedbed preparation Rotary tiller or harrow PTO and implement compatibility
Land leveling Leveling blade or grader Stable low-speed control
Seeding Seeder or planter Hitch, PTO and hydraulic compatibility
Ditching Agricultural ditcher Traction and directional control
Orchard maintenance Mower, tiller or sprayer Compact dimensions and maneuverability

The best application for a crawler tractor is one where its traction, flotation and low-speed control provide a practical advantage over a wheeled machine.

How to Choose a Crawler Tractor


Choosing a crawler tractor requires more than comparing engine power and purchase price. The machine should match the intended work, field conditions, implements, operating space and maintenance resources.


Define the Main Agricultural Tasks

Start by identifying the work the tractor must complete.

Common tasks include:

  • Rotary tillage

  • Plowing

  • Harrowing

  • Seeding

  • Ditching

  • Fertilizing

  • Land leveling

  • Orchard maintenance

A tractor designed mainly for light rotary tillage may not provide the weight or pulling capacity required for deep plowing. List the main tasks before comparing models.


Match Engine Power to the Implement

Engine power should be selected according to the implement, working width, soil resistance and required operating speed.

Before choosing a model, confirm:

  • Recommended implement horsepower

  • PTO power and speed

  • Hydraulic flow and pressure

  • Hitch or connection type

  • Maximum implement weight

  • Required working depth

Avoid choosing power based only on farm size. Heavy clay, deep tillage and wide implements may require more power than light work on larger areas.


Choose the Right Track Width

Track width affects flotation, traction, turning and machine width.

Wider tracks may be considered for:

  • Soft or wet soil

  • Paddy fields

  • Conditions with limited soil-bearing capacity

Narrower tracks may be suitable when:

  • Field entrances are restricted

  • Crop rows are narrow

  • The ground is firm

  • Lower turning resistance is important

Compare track width together with total machine weight and effective ground-contact length.


Check Tractor Size and Maneuverability

Measure the areas where the tractor will operate and be stored.

Important dimensions include:

  • Overall width

  • Overall height

  • Overall length

  • Minimum ground clearance

  • Turning radius

  • Track gauge

  • Implement width

A small or compact crawler tractor may be more practical in orchards, vineyards, terraces and narrow fields. Larger models may provide more pulling capacity but require wider entrances and greater turning space.


Confirm Implement Compatibility

Not every crawler tractor can operate every agricultural attachment.

Ask the supplier to confirm compatibility with:

  • Rotary tillers

  • Plows

  • Harrows

  • Seeders

  • Ditchers

  • Fertilizer applicators

  • Leveling equipment

  • Mowers

Check PTO specifications, hydraulic requirements, connection points, lifting capacity and working width before purchasing attachments.


Evaluate Field and Soil Conditions

Choose the undercarriage according to the most difficult conditions expected during regular operation.

Consider:

  • Soil type

  • Typical moisture level

  • Field slope

  • Surface strength

  • Mud depth

  • Crop-row spacing

  • Field entrances

  • Distance between fields

Tracks can improve traction and flotation, but they do not make every wet field or slope safe.


Calculate the Total Ownership Cost

The total cost includes more than the tractor price.

Compare:

  • Fuel consumption

  • Routine servicing

  • Track and undercarriage wear

  • Replacement parts

  • Hydraulic maintenance

  • Labor

  • Storage

  • Downtime

  • Expected resale value

A lower-priced crawler tractor may cost more over time if spare parts are difficult to obtain or the undercarriage wears quickly.


Review Spare Parts and Technical Support

Before purchasing, confirm whether the supplier provides:

  • Operating manuals

  • Maintenance schedules

  • Parts lists

  • Operator guidance

  • Troubleshooting support

  • Warranty terms

  • Replacement-part availability

  • Service procedures

Support is especially important during planting and land-preparation seasons when equipment downtime can delay field work.

Crawler Tractor Maintenance Checklist

Regular maintenance helps reduce unexpected downtime and excessive wear. Service intervals vary by model, engine and working conditions, so always follow the manufacturer’s operation and maintenance manual.

Stop the engine, lower attached implements and secure the tractor before inspection or repair.


Checks Before Each Operation

Before starting work, inspect:

  • Engine oil level

  • Coolant level

  • Fuel supply

  • Hydraulic fluid level

  • Visible leaks

  • Track condition and tension

  • Rollers, idlers and sprockets

  • Loose or damaged fasteners

  • Hoses and electrical connections

  • Brakes and steering controls

  • Lights and warning indicators

  • Attached implement and connection points

Remove mud, stones, crop residue and other material from the undercarriage. Debris buildup may interfere with track movement or hide damaged components.


Track and Undercarriage Maintenance

The undercarriage is one of the most important maintenance areas on a crawler tractor.

Check for:

  • Incorrect track tension

  • Damaged or missing track components

  • Worn drive sprocket teeth

  • Leaking or damaged rollers

  • Loose pins and bushings

  • Uneven track wear

  • Debris trapped around the undercarriage

Track tension should follow the manufacturer’s specification. Excessive tension may increase component wear, while insufficient tension may allow the track to derail.


Engine and Cooling System Maintenance

Service the engine according to operating hours and the manufacturer’s schedule.

Typical maintenance items include:

  • Engine oil and oil filter

  • Fuel filter

  • Air filter

  • Cooling system

  • Radiator and cooling surfaces

  • Belts and hoses

  • Battery and electrical connections

Dust, mud and crop residue can restrict cooling airflow. Clean the radiator and ventilation areas regularly without damaging the fins.


Hydraulic and Transmission System Maintenance

Check hydraulic hoses, fittings and cylinders for leaks, abrasion or damage. Use only the specified fluid and filter types.

Also inspect:

  • Transmission fluid level

  • Hydraulic fluid condition

  • Hydraulic filters

  • Cylinder rods and seals

  • PTO connections

  • Final-drive housings

  • Steering response

Do not check hydraulic leaks with bare hands. High-pressure fluid can penetrate the skin and cause serious injury.


Implement and Attachment Inspection

Before using a plow, rotary tiller, seeder, ditcher or other implement, confirm that:

  • Connection points are secure

  • Guards and covers are installed

  • PTO shafts are correctly connected

  • Hydraulic couplings are locked

  • Blades and working parts are not damaged

  • The implement moves through its full range safely

Stop the tractor before clearing blocked material or adjusting the implement.

Maintenance by Operating Hours

Oil, filters and other service items should be replaced according to operating hours rather than a universal weekly or monthly schedule.

Maintenance Area Recommended Approach
Engine oil and filters Follow the engine manufacturer’s hour-based interval
Hydraulic fluid and filters Follow the tractor service schedule
Transmission and final drives Inspect and service at specified operating hours
Track tension Check regularly and adjust to specification
Rollers and sprockets Inspect for wear, damage and leakage
Lubrication points Grease according to the maintenance chart
Safety systems Test before use and during scheduled service

Shorter service intervals may be required in dusty, muddy, wet or high-load conditions.

Seasonal Storage

Before extended storage:

  • Clean the tractor and undercarriage

  • Remove soil, mud and crop residue

  • Complete scheduled oil and filter service

  • Check coolant and freeze protection

  • Inspect tracks and reduce unnecessary track stress

  • Protect exposed metal surfaces

  • Disconnect or maintain the battery as instructed

  • Store the tractor in a dry, covered location

  • Record maintenance and unresolved faults

Inspect and test the tractor before returning it to service.

Common Problems and Initial Checks

Problem Initial Checks
Tractor pulls to one side Track tension, steering control and undercarriage wear
Excessive track slip Soil condition, track wear, implement load and operating technique

Engine overheats Coolant level, radiator cleanliness, fan and belt condition
Unusual undercarriage noise Rollers, sprockets, idlers, track tension and trapped debris
Difficult starting Battery, fuel supply, filters and electrical connections

These checks help identify possible causes but do not replace model-specific diagnosis. Stop operating the tractor if a fault may affect safety or cause further damage.


Frequently Asked Questions About Crawler Tractors


What Is a Crawler Tractor?

A crawler tractor is a tractor that travels on continuous tracks instead of conventional tires. The tracks distribute the machine’s weight over a larger contact area, helping improve traction and stability on soft, wet, loose or uneven ground.


What Is a Crawler Tractor Used For?

Crawler tractors are commonly used for plowing, rotary tillage, land leveling, ditching, seedbed preparation and other agricultural operations. They are especially useful in rice fields, muddy farmland and areas where wheeled tractors may experience excessive slipping or sinking.


How Does a Crawler Tractor Turn?

A crawler tractor turns by changing the speed or driving force applied to its left and right tracks. Depending on the machine design, the steering system may slow, brake or independently control one track to change direction. The exact turning method varies by transmission and steering configuration.


Is a Crawler Tractor Better Than a Wheeled Tractor?

Neither type is better for every application. A crawler tractor generally provides better traction and flotation on soft or wet soil, while a wheeled tractor usually offers faster travel speeds and easier road transportation. The right choice depends on field conditions, operating tasks and transport requirements.
