Kubota KX61-3 & KX71-3 rubber track size
| Track size | Width | Pitch | Links | Replaces OEM |
|---|---|---|---|---|
| 300 x 52.5 x 80 | 300mm (≈11.8″) | 52.5mm | 80 | Kubota 400/M6840 |
The size is written as width x pitch x links — so 300 x 52.5 x 80 is 300mm wide, 52.5mm pitch, 80 drive links. This is the standard fitment for the KX61-3 and KX71-3. The same 300 x 52.5 x 80 track also fits a number of other Kubota machines including the KX027-4, U25-3 and U27-4, which is why it’s one of the most common Kubota sizes we supply.
Which tread should I choose?
- Block / multi-bar (standard) — the all-round factory-style tread. Strong grip on mixed ground, comfortable ride and good wear life. The right choice for general groundwork, drainage and site work.
- Zig-zag / staggered — extra bite for soft, wet or sloping ground where the standard block starts to slip.
Will it fit my KX61-3 or KX71-3?
These tracks are built to the same dimensional spec as the original Kubota fitment — same 300mm width, 52.5mm pitch and 80-link count, same steel-corded reinforced rubber construction. They run on the standard sprockets and rollers and bolt straight on. If the size has worn off your old track, the 300 x 52.5 x 80 is the correct standard size for the KX61-3 and KX71-3; if in doubt, measure the width across the ground-contact face and count the links, or just give us your machine and serial number.

Frequently asked questions
What size rubber tracks does a Kubota KX61-3 take?
The Kubota KX61-3 takes a 300 x 52.5 x 80 rubber track (300mm wide, 52.5mm pitch, 80 links). The same size fits the KX71-3 and replaces Kubota OEM part 400/M6840.
Is the KX71-3 track the same as the KX61-3?
Yes. Both the Kubota KX61-3 and KX71-3 use the 300 x 52.5 x 80 rubber track, so the same replacement set fits either machine.
Are aftermarket Kubota tracks as good as OEM?
A quality aftermarket track is built to the same size and steel-corded construction as the Kubota OEM track, so it fits the same sprockets and rollers and wears the same — at a much lower price.
How long do Kubota KX61-3 tracks last?
Expect roughly 1,200–2,000 hours depending on ground conditions, tension and how the machine is worked. Correct track tension and avoiding hard turns on abrasive surfaces extends their life.
