The Ditch Witch JT520 runs a 180x72x39 track: 180 mm across the tread, 72 mm between links, 39 links around. Cut for bore setups, utility installs and pit-to-pit moves and shipped free to the lower 48.
What the numbers mean on a Ditch Witch JT520
180x72x39 — 180 mm tread width (about 7"), 72 mm pitch, 39 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 Ditch Witch JT520
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
C-Block — concrete, asphalt and hard-packed ground. Longest wear life and the least vibration on hard surfaces
Directional — digging, trenching and slope work. The standard excavator tread
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.

How these wear
Drills sit still under load and travel short distances, so tracks usually age out from compound fatigue rather than mileage. 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 180x72x39 shows up on machines from several makers. If you run any of these alongside the Ditch Witch JT520, 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.
