Yanmar B12-3PR replacement rubber tracks are built for excavation, trenching, grading, and repeated travel. The listed application uses 230x72x43.
TrackTECH heavy-duty construction combines additional rubber wear material with continuous internal steel reinforcement to support repeated steering, travel, and abrasive jobsite conditions.
Available tread patterns are chosen around real jobsite priorities such as cleanout, pushing bite, stable grading, and predictable travel. Confirm the physical track size first, then select tread around the work surface.
Width, pitch, link count, and guide geometry must match the machine. Inspect sprockets, rollers, idlers, alignment, and track tension before installation because undercarriage condition directly affects belt wear and tracking.
TrackTECH provides fitment support before shipment and 24-month warranty coverage against manufacturing defects.
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.
Precision-matched to the correct track width, pitch, link count, and guide configuration for your machine.
Continuous internal steel cord construction eliminates overlapping cord joints and helps maintain consistent strength around the full track.
Construction-grade rubber and reinforced internal components are built for demanding jobsites and long service life.
Heavy-duty steel track guides are treated for corrosion resistance and built to handle repeated undercarriage loads.
Backed by TrackTECH's 24-month rubber track warranty for materials and workmanship.
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.
