The Case 440CT is cataloged in more than one track width — 320 / 400 mm. Pick the width your undercarriage is actually set up for, then choose tread for the ground you work. Free freight to the lower 48 on every track, 24-month warranty.
Which width fits your Case 440CT
400x86x50 — 400 mm (16") wide, 86 mm pitch, 50 links
320x86x50 — 320 mm (13") wide, 86 mm pitch, 50 links
These are not interchangeable by preference — the width your machine takes is set by the roller frame and sprocket it left the factory with. Wider tread floats better on soft ground and spreads ground pressure; narrower runs cheaper, turns easier and clears tight spots. Measure the existing track across the tread face before you order.
Tread choice for the Case 440CT
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
Multi-Bar — mud, snow and soft ground. Deep bar lugs bite and shed material instead of packing up
Zig-Zag — general mixed ground. Balanced traction with a smoother ride than a bar tread
Staggered Block — mixed dirt and gravel. Block stability with better cleanout than a straight block
C-Block — concrete, asphalt and hard-packed ground. Longest wear life and the least vibration on hard surfaces
X-Terrain — the worst ground you have. Aggressive lugs for mud, slope and loose fill
All-Terrain — everything in between. A compromise tread when the machine moves between surfaces
If the machine splits its time between surfaces, buy for the ground you are on most — a hard-surface tread on constant mud will spin, and a bar tread on concrete will wear out in half the hours.

Undercarriage parts for the Case 440CT
Rollers, idlers and sprockets wear on the same clock as the track. Fitting new rubber over a hooked sprocket or a seized roller is the fastest way to lose the new track — check these while the tracks are off:
CTLs run high ground speed and counter-rotate all day, which is what eats edge lugs and drive lugs first. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines
Track size follows undercarriage geometry, not brand, so one of these sizes shows up on machines from several makers. If you run any of these alongside the Case 440CT, it is the same belt:
Not sure which you are running? Read the size off the inside of the old track, or call (850) 816-7898 and we will pull it off the machine record. The Track Finder works by make and model too.
