Heavy-duty replacement rubber tracks for the Bobcat T66 Compact Track Loader. Track width and tread pattern directly influence traction, push force, flotation, ride quality, ground disturbance, cleanout, and wear. Choose the combination around the work the machine performs most.
320x86x50: The narrower footprint increases ground pressure for strong push force, tighter access, and lower replacement cost.
400x86x50: The wider footprint improves flotation, lowers ground pressure, and reduces surface disturbance in soft ground.
C-Block, Multi-Bar, and Zig-Zag are offered across both widths; Staggered Block is offered on the 320 mm configuration.
Advanced abrasion-resistant rubber, a continuous steel-cord core, and drop-forged, heat-treated steel links provide the strength required for repeated pushing, turning, loading, and side-loads. The reinforced internal structure helps maintain consistent sprocket engagement while resisting stretching, cuts, tearing, chunking, and premature abrasion.
New tracks work as part of the complete undercarriage. Inspect sprockets, rollers, idlers, alignment, and track tension before installation. Worn mating components or incorrect tension can accelerate track wear, reduce ride quality, and shorten service life. Set final track tension to the machine manufacturer's service specification.
Nationwide fulfillment is available, backed by a 24-month warranty against manufacturing defects and application support when needed.

ENGINEERED FOR THE JOBSITE
Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
Tread Pattern Guide
Compare common TrackTECH rubber track tread patterns by traction, ride comfort, surface protection, and jobsite conditions.
Balanced Jobsite Performance
Best for: general construction, dirt, gravel, clay, and mixed jobsite use.
C-Block tracks are a strong all-around option for compact track loaders working across everyday jobsite conditions. They provide dependable traction, a stable ride, and balanced wear life without being overly aggressive on the ground.
Aggressive Traction
Best for: mud, loose soil, slopes, clay, and soft ground.
Zig-Zag tracks use an alternating lug design to improve bite and help the track clean out in loose or wet conditions. This pattern is a strong choice when traction and hillside control matter more than surface protection.
Severe-Duty Terrain
Best for: forestry, mulching, extreme land clearing, and the most severe off-road environments.
Designed for high-horsepower CTLs in dense brush, jagged terrain, and debris-heavy conditions. The most aggressive TrackTECH tread for severe duty — built for durability, puncture resistance, and relentless traction when clearing heavy brush or earth.
Fortified Core Defense: ultra-reinforced center guide deflects stumps, jagged rocks, and sharp forestry debris from the core. Maximum Bite: deep aggressive lugs deliver uncompromising forward drive from deep clay to heavy snowpack.
Trade-off: overkill on sensitive turf or finished pavement — runs rough and will tear up the ground. Ideal surfaces: mulch/brush, deep clay, jagged rock, snow.
Mini Excavator Control
Best for: mini excavators, trenching, grading, utility work, and mixed surfaces.
Directional tracks are commonly used on mini excavators where forward traction, controlled movement, and dependable wear are important. This pattern helps provide predictable movement across dirt, gravel, clay, and general excavation conditions.

TrackTECH supplies the machine-specific rubber track configurations listed for the Bobcat T66. 100% Precision Fitment. Guaranteed.
Available tread patterns vary by track configuration and jobsite. The options shown for the Bobcat T66 are selected for applications such as construction, dirt, gravel, mud, snow, landscaping and mixed terrain.
Yes. Inspect rollers, idlers, sprockets and track tension when installing replacement tracks. Worn undercarriage components can contribute to uneven wear, poor tracking and reduced service life.
