One track size, broad machine coverage. The 300x52.5Nx78 Heavy Duty rubber track (12-inch) fits verified applications including Bobcat E25, Case CX26, Case CX26C, Hitachi EX20UR-2, Hitachi EX20UR-3, and Hitachi EX25U plus 14 additional verified machines. This 78-link configuration serves mini excavators across demanding work environments.
Maximize Uptime. Lower the Cost Per Hour. A failed track costs more than the replacement—it costs production time. This Heavy Duty replacement track is built for contractors and fleets that need dependable machine availability, predictable wear and useful traction instead of mid-job interruptions.
TrackTECH Advantage:
- Continuous Steel Cord: Jointless internal steel cable construction removes splice points and reinforces the track against stretching and high-load stress.
- Forged Steel Links: Heat-treated internal guide links support consistent sprocket engagement under repeated torque and load cycles.
- Wear & Ground Contact: Heavy-duty lug geometry balances traction, footprint stability and long-wearing contact across everyday jobsites.
- Controlled Travel: Tread geometry is selected for predictable forward and reverse movement during digging, trenching and repositioning.

ENGINEERED FOR THE JOBSITE
Built Tough
Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.
-
100% Virgin Rubber
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
-
Continuous Steel Cords
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
-
Drop-Forged Links
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
-
Corrosion Resistant
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
-
Reinforced Sidewalls
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
-
Low-Vibration Tread
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
