This heavy-duty replacement rubber track is built to the 400x72.5Wx74 specification and uses the MX tread pattern. Match the complete belt dimensions and guide style to the machine before ordering rather than selecting by width alone.
TrackTECH heavy-duty construction combines additional rubber wear material with continuous internal steel reinforcement to support repeated travel, steering, pushing, and jobsite abrasion. Internal steel components support consistent engagement through the sprocket and roller path.
The directional/general-purpose layout supports stable ground contact, predictable travel, and dependable traction across dirt, gravel, clay, and mixed work surfaces.
Width, pitch, link count, and guide geometry must all match the application. Confirm the complete 400x72.5Wx74 specification or send the machine make and model to TrackTECH for fitment confirmation before shipment.
Inspect sprocket teeth, rollers, idlers, alignment, and track tension before installation. Worn components can create uneven loading and premature belt wear.
TrackTECH provides fitment support before shipment and 24-month warranty coverage against manufacturing defects.
Awesome dude to work with. Doesn't beat around the bush. Got my tracks when he said I would and they seem to be good quality for the price. Will buy here again!

Britton went above and beyond anything I was expecting. Tracks got ordered and paid for and delivery was prompt with absolutely no hang ups. I was notified three hours prior and sent pictures once completed. Absolutely a dream to deal with. Highly recommend.
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.

Fitment, availability, fulfillment, and support for this product
The 400x72.5x74 uses 400x72.5x74 rubber tracks (Width: 400mm, Pitch: 72.5mm, Links: 74). This product is the Directional tread option, built for dependable traction and jobsite durability. Always verify the size stamped on your existing track or use the <a href="/pages/rubber-track-finder">TrackTECH Rubber Track Finder</a> before ordering.
Matching drive sprocket options for the 400x72.5x74 include <a href="/products/sprocket-2054978">Drive Sprocket | Part #SP2054978</a> and <a href="/products/sprocket-rd411-14432">Kubota Drive Sprocket | Part #SPRD411-14432</a>. When installing new rubber tracks, inspect sprockets for hooked, sharp, or uneven teeth because worn sprockets can shorten track life and damage the drive lugs.
Matching bottom roller or track roller options for the 400x72.5x74 include <a href="/products/bottom-roller-9239528">Bottom Roller | Part #TR9239528</a>, <a href="/products/bottom-roller-rd441-21702">Kubota Bottom Roller | Part #TRRD441-21702</a>, <a href="/products/bottom-roller-rd411-21700">Kubota Bottom Roller | Part #TRRD411-21700</a>, and <a href="/products/bottom-roller-rd411-21703">Kubota Bottom Roller | Part #TRRD411-21703</a>. Replacing worn rollers before installing new rubber tracks helps keep the undercarriage aligned and reduces uneven wear across the track carcass.
Matching front idler options for the 400x72.5x74 include <a href="/products/front-idler-rd411-22303">Kubota Front Idler | Part #FIRD411-22303</a>. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.
Matching top roller options for the 400x72.5x74 include <a href="/products/carrier-roller-20t-30-00050">Komatsu Top Roller | Part #CR20T-30-00050</a>. Top rollers support the upper track path and should be checked for bearing play, flat spots, and uneven wear during undercarriage service.
Yes, inspect sprockets, rollers, and idlers before installing new rubber tracks on the 400x72.5x74. Worn undercarriage parts can shorten track life, cause poor alignment, and create uneven wear. Shop matching parts from the linked products above or view <a href="/collections/all-undercarriage-parts">all undercarriage parts</a>.
Confirm fitment by checking your machine make, model, serial number, and existing track size or OEM part number. For rubber tracks, verify width, pitch, and link count. For undercarriage parts, compare the part number, bolt pattern, tooth count, and machine position. You can also use the <a href="/pages/rubber-track-finder">TrackTECH Track Finder</a> or call <a href="tel:8508167898">(850) 816-7898</a> before ordering.
