Constructed using Continuous Cord Technology. The multi-layer steel cord is wound in a continuous loop without joints, increasing the track's tensile strength by 40% compared to standard jointed aftermarket tracks.
Key Technical Advantages:
- Reinforced Core: Solid forged steel inserts provide lateral stiffness, preventing de-tracking when maneuvering on soft terrain.
- Wear Resistance: A rubber compound enriched with polymers extends tread life even when working on rocky ground.
- Vibration Reduction: The tread profile is designed to minimize vibrations transferred to the machine's undercarriage.

Service Tip: When installing a new track, always inspect the undercarriage. Running a new track on a worn
drive sprocket or damaged idler will drastically shorten the track's lifespan.
Frequently Asked Questions (FAQ)
Why is the 81.5 mm pitch important?
In this machine class, there are three similar pitches: 81 mm, 81.5 mm, and 83.5 mm. The differences are minimal, but installing the wrong pitch will destroy the sprocket. This model has an 81.5 mm pitch. Please verify the marking on your old track or measure the link center-to-center distance.
Does it fit Takeuchi TB175?
Not always. The Takeuchi TB175 often uses a 450 mm track with an 81 mm pitch (not 81.5 mm). We recommend verifying the machine serial number or contacting us before purchasing for this specific model.
