The Ultimate 2026 AGCO® Challenger® Fendt® and Massey Ferguson® Tractors and Combines Rubber Track Reference Guide
Table of Contents
1. Introduction and Track Terminology
Farming operations across the world are unique. Working closely with track tractor and combines owners, We have created an extensive line of tracks to fit virtually any application. This guide is intended to help you better understand the complete line of tracks for tractors and provide helpful recommendations for the best use of each type.
All tractor tracks are built by us using an exclusive manufacturing process that keeps each component in place, resulting in a stronger track.
To choose the best track for your operation, carefully consider your applications:
■ Cropping patterns
■ Typical field conditions, soil types and terrain
■ Implements used
■ Amount of road travel
With knowledge of your local conditions and applications, we can help you use this guide to find the best track for your operation.
1.1 Agricultural Track Terminology
Our tracks are constructed using a combination of natural and synthetic rubber in combination with steel reinforcing plies and continuous wound main cables. The main cables give the track tension strength. The bias and reinforcement plies protect the main cables, provide internal track alignment, and further increase lateral stiffness to better distribute loads across the track width. The tread bars are designed with specific shapes, with each shape giving a distinct performance advantage in specific applications.

2. TRACK MACHINE OPERATIONAL GUIDELINES
2.1 New Track Break-In
Tracks should be operated in dry soil as soon as possible after new installation Track guide and drive lugs, especially on new machines, benefit from correct break-in procedures. Correct break-in through immediate introduction of the track into dry soil helps reduce the initial amount of heat generation. Track components undergo a polishing-in process during the break-in period. During this time, flash is worn from wheel edges and a smooth steel to rubber interface is developed. New rubber surfaces benefit from frequent contact with the soil, which acts as a dry lubricant, and will facilitate smooth break-in and minimize heat during break-in activities. Improper break-in may result in scuffs and poor appearance to the side of the guide or drive lugs, This will polish over once proper break-in procedures are resumed. Any significant transport distances before introduction in the field should be avoided or heat related damage to track and system components can result.
2.2 Maintain Track Alignment
Track alignment should be checked periodically (per machine operator manual instructions), especially during break-in. Alignment may change throughout the life of the machine due to track or track system component wear. Significant misalignment may result in heating and accelerated wear to one side of the guide or drive lug, as well as cause heat related damage to the midrollers and drive wheels.
The most common way to verify alignment is through use of a shim to check guide or drive lug clearance with the front midrollers by driving a fixed distance and coasting to a stop on a flat hard surface. See your machine operators manual for proper procedures for checking and adjusting alignment on your specific platform.
Temperature differential between the inner and outer surface of a guide or drive lug can also be used as a secondary step to refine the alignment, if needed. However, it is acceptable to have some temperature differential remaining once the machine passes the shim check. As long as the temperature differential is maintained at less than 20 oC (40 oF), as measured during road transport, no further alignment adjustment should be required.
2.3 Correct Operational Techniques
Tracks can pull more – so reduce loads at low speeds
Tracks deliver much less slip in high torque, low speed operations. Follow the operator’s manual guidelines and stay above the minimum speed for full load operation. Never exceed the maximum ballasted weight in order to gain more traction in lower gears.
Use proper amounts of ballast
Ballast the tractor to achieve no less than 2-5% slip under heavy pull conditions. In addition, the best track performance comes from even weight distribution along the entire track length. Correct ballast will result in reduced tread bar wear, longer rolling component life, less compaction, and improved ride and turning performance.
Maintain correct track tension
In a friction drive system, proper track tension is critical to achieve maximum tractive performance. Inadequate tension can allow more material between the track and wheels, allow track to drive wheel slip, and increase the potential for untracking.
Keep material out of the track
Track systems are designed to allow for some amounts of material to pass between the drive wheel and track. However, uncompressable objects will cause very high localized track loading, which can result in chips, chunks, and tears in the track and undercarriage components. In addition, excessive material build-up inside the undercarriage can cause the tensioning system to run out of recoil. If recoil is used up, track tearing can occur. If a tractor becomes stuck, always dig out the undercarriage and pull the machine out backwards to avoid track damage.
Use care when crossing ditches or transitions
Track machines have certain maneuvers that should be approached with care. One example is during a transition from a sloped to a flat area, especially if transitioning at a diagonal. If dynamic turning is attempted during the transition, the risk is higher for untracking to occur. Operate at low speeds, and avoid turning, to minimize the risk of untracking in these situations.
3. CHALLENGER MT700 SERIES (A THRU E SERIES) TRACK SELECTION (348 IN TRACK CIRCUMFERENCE)
The Challenger MT700 Series tractors offer more undercarriage options than ever before, increasing the versatility of your tractor.
The tracks are tensioned by a nitrogen accumulator and hydraulic cylinder. Track tension pressure should be maintained at 2950 psi (20,339 kPa). This creates a track tension of 16,000 lbs (7257 kg). Track tension pressure can be monitored utilizing the tractor monitor screen on most MT700 Series Tractors. High and low pressure alarms warn the operator of potential issues.
Correct track tension pressure should be maintained to reduce damage to the tracks. Refer to the Operation and Maintenance Manual (OMM) for procedures to properly maintain track tension.

8. FENDT IDEAL COMBINE TRACK SELECTION
General Facts
- Produced from 2018 to current
- 450 to 650 HP
- 298 in (7560 mm) track length
- Positive Drive Track System
- Models Affected: Ideal 7T, Ideal 8T, Ideal 9T, Ideal 10T
Our positive drive tracks are constructed using natural and synthetic rubber in combination with steel reinforcing layers and main cables. The continuous wound main cables give the track tensile strength to carry the main load and resist breakage. The bias alignment plys aid in track alignment and the reinforcing plies protect the main cables. The treadbars are designed to provide roading wear life, resistance to wear in the field, and provide optimum traction for varied conditions and applications. The drive lugs are designed to engage the drive bars on the drive wheel to transfer the loads of traction and braking, and to ensure engagement of the track between the idler and midrollers.

10. BOLT-ON REPLACEMENT GUIDE LUGS
- Used to replace missing or worn guide lugs on tracks with greater than 50% of tread life remaining.
- Guide lug design distributes forces across the entire length of the guide lug improving replacement guide lug durability and retainability.
- The retaining plate is designed to prevent damage to the guide lug when high stresses are applied to the guide lug.
- Guide lug material is the same material as the guide lugs on new tracks providing consistent wear.
- Bolt-on guide lugs can be an economical way to increase the life of tracks in certain conditions.

12. CHALLENGER MT700/MT800 WHEEL REPLACEMENT CRITERIA
12.1 Idler Wheel
The idler wheels are the front wheels. The idler wheels are attached to the track tensioning system and provide the tension on the track. They also aid in adjustment of track alignment.
Idler Wheels should be replaced if:
- Rubber material is worn or missing
- Steel hub is cracked or damaged

12.2 Midroller
Midrollers carry most of the weight for the tractor.
Midrollers will wear over time and are susceptible to heat buildup from roading, track misalignment, and side hill applications. In most applications, rubber midrollers will provide adequate life. In harsh applications, poly midrollers may improve life of the midroller and should be used.
Midrollers should be replaced if:
- Rubber/Poly material is missing/worn all the way across the width of the midroller.
- 1/3 of the rubber/poly material is missing/worn all the way around the midroller.
- Rubber/poly material is worn thin enough that material is sticking to the midroller.
- Steel hub is cracked or damaged
- Midroller is no longer round (flat spot worn into surface)

12.3 Drive Wheel
Drive wheels provide the friction drive to the inside surface of the track to transfer the engine power to the ground. The friction surface is determined by the depth and sharpness of the chevrons cut into the drive wheel surface.
Drive wheels should be replaced if:
- Rubber material is missing or worn resulting in excessive drive wheel to track slippage.
- Steel hub is cracked or damaged

For best performance, tracks should be replaced when:
■ Tread bar height is less than 0.5 in (12 mm)
■ Track to ground slippage consistently exceeds 10%
■ Several (more than 3) tread bars are missing in a row
■ Multiple (more than 5) guide lugs are missing consecutively
■ 1 or more drive lugs are missing
■ Guide lugs have excessive wear (50% of guide lugs is worn)
■ De-tracking occurs due to worn or missing guide lugs
■ The main cables have torn in the wheel path (Tear across the width of the carcass)
■ Cables are showing on the inside surface of the track
■ Drive wheel to track slippage is excessive due to missing ID rubber or rubber surface is glazed/hardened from drive wheels slipping.
