The Case 440CT uses a rubber-track undercarriage designed for grading, loading, site preparation and attachment work. The 400x86x50 track setup gives the machine a stable footprint for traction, ride quality and controlled ground pressure.
TrackTECH Heavy Duty options use a 100% virgin rubber compound, continuous vulcanized steel cord and forged steel embeds to maintain pitch alignment under travel, turning and attachment loads. Premium Bridgestone options, where shown, are offered as an additional track-line choice for customers who prefer a premium manufacturer option.
Inspect the sprockets, rollers, idlers and tension system before installing new tracks. Hooked teeth, seized rollers or incorrect tension can shorten the life of a new belt.
TrackTECH Heavy Duty warranty: 24 months against defects in 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.

Common questions about Case 440CT rubber tracks
The Case 440CT uses 320x86Bx50 rubber tracks (Width: 320mm, Pitch: 86mm, Links: 50). Always verify the size stamped on your existing track or use the TrackTECH Rubber Track Finder before ordering.
Matching drive sprocket options for the Case 440CT include Case 440CT Sprocket | Part #87460888. 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 Case 440CT include Case 440CT Track Roller | Part #87535297. 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 Case 440CT include Case 440CT Front Idler | Part #87535298. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.
Matching rear idler options for the Case 440CT include Case 440CT Rear Idler | Part #87535299. A worn rear idler can contribute to poor track alignment, derailment, and premature edge wear, especially after new rubber tracks are installed.
The 320x86Bx50 rubber track size is used across multiple compact machines, including 320x86x50, Bobcat T66, Bobcat T62, Bobcat T64, Case 420CT, Case TR310B, Case M400T, and Case TR310. Always confirm by checking the size stamped on your current track and your machine serial number before ordering.
Yes, inspect sprockets, rollers, and idlers before installing new rubber tracks on the Case 440CT. Worn undercarriage parts can shorten track life, cause poor alignment, and create uneven wear. Shop matching parts from the linked products above or view all undercarriage parts.
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 TrackTECH Track Finder or call (850) 816-7898 before ordering.
