Replacement rubber tracks for the Kubota KH040 mini excavator in 400x72.5Wx74 — 400 mm wide, 72.5 mm pitch, 74 links. Built for digging, trenching, backfill and tight-quarters work, with free freight to the lower 48.
What the numbers mean on a Kubota KH040
- 400x72.5Wx74 — 400 mm tread width (about 16"), 72.5 mm pitch, 74 links, wide guide lugs
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 Kubota KH040
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
- MX — mixed and hard surfaces. A durable general-duty 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
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. 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 400x72.5Wx74 shows up on machines from several makers. If you run any of these alongside the Kubota KH040, it is the same belt:
