The Case TV450 is cataloged in more than one track width — 400 / 450 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 TV450
450x86x55 — 450 mm (18") wide, 86 mm pitch, 55 links
400x86x55 — 400 mm (16") wide, 86 mm pitch, 55 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 TV450
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
All-Terrain — everything in between. A compromise tread when the machine moves between surfaces
C-Block — concrete, asphalt and hard-packed ground. Longest wear life and the least vibration on hard surfaces
Multi-Bar — mud, snow and soft ground. Deep bar lugs bite and shed material instead of packing up
X-Terrain — the worst ground you have. Aggressive lugs for mud, slope and loose fill
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
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 TV450
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:
Where more than one part number is listed, Case changed that component across serial ranges. Match the number stamped on the part you are replacing, or send us the machine serial and we will pick it.
How these wear
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 TV450, 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.
