The Ditch Witch SK500 is cataloged in more than one track width — 180 / 230 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 Ditch Witch SK500
- 230x72x39 — 230 mm (9") wide, 72 mm pitch, 39 links
- 180x72x39 — 180 mm (7") wide, 72 mm pitch, 39 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 Ditch Witch SK500
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.
Undercarriage parts for the Ditch Witch SK500
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:
How these wear
Stand-on loaders spend their life on curbs, trailers and hard surfaces, so abrasion is the usual failure mode, not cracking. 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 Ditch Witch SK500, it is the same belt:
- Bobcat 418
- Bobcat E08
- Bobcat E10
- Bobcat MT50
- Bobcat MT52
- Bobcat MT55
- Bobcat X418
- Boxer 400
- Boxer 427
- Boxer 526DX
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.
