The John Deere CT315 runs a 380x86x52 track: 380 mm across the tread, 86 mm between links, 52 links around. Cut for grading, loading, pallet work and land clearing and shipped free to the lower 48.
What the numbers mean on a John Deere CT315
380x86x52 — 380 mm tread width (about 15"), 86 mm pitch, 52 links
Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.
Tread choice for the John Deere CT315
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
Staggered Block — mixed dirt and gravel. Block stability with better cleanout than a straight block
Undercarriage parts for the John Deere CT315
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.

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.
