Kubota U25-3 Rubber Tracks

The Kubota U25-3 takes a 300 mm track, but it was built with more than one pitch — 52.5 and 53 mm. Same width, different drive-lug spacing, and they do not swap. Check the old track or the sprocket before ordering. Free freight to the lower 48, 24-month warranty.

Kubota U25-3 track options

  • 300x52.5Nx80 — 300 mm (12") wide, 52.5 mm pitch, 80 links, narrow guide lugs
  • 300x53x80 — 300 mm (12") wide, 53 mm pitch, 80 links

Same tread width on all of them — what changes is pitch and link count, which is set by the sprocket and roller frame. Read the numbers off the inside of the old track rather than going by model year; these were built across more than one undercarriage spec.

Tread choice for the Kubota U25-3

Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:

  • MX — mixed and hard surfaces. A durable general-duty excavator tread
  • 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 Kubota U25-3

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:

Where more than one part number is listed, Kubota changed that component across serial ranges. Match the number stamped on the part you are replacing, or send us the machine serial and we will pick it.

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 one of these sizes shows up on machines from several makers. If you run any of these alongside the Kubota U25-3, it is the same belt:

  • 100% Virgin Rubber

    Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

  • Continuous Steel Cords

    Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

  • Drop-Forged Links

    Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

  • Corrosion Resistant

    The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

  • Reinforced Sidewalls

    Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

  • Low-Vibration Tread

    Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.

Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What rubber tracks are compatible with the Kubota U25-3?
The Kubota U25-3 is cataloged with multiple track configurations: 300x53x80, 300x52.5Nx80.
What are the best rubber tracks for the Kubota U25-3?
The best Kubota U25-3 track depends on terrain and application. Current tread choices include MX — mini excavator replacement use across hard and mixed surfaces. Compare traction, ride quality, cleanout, ground disturbance and wear for the work you do most.
Where can I buy new tracks for a Kubota U25-3?
TrackTECH offers new heavy-duty replacement tracks for the Kubota U25-3 with low direct pricing, free shipping, fast nationwide delivery and 24-month rubber-track warranty protection. Current prices and available tread options are shown on the page.
How much do Kubota U25-3 rubber tracks cost?
Price depends on track size, tread pattern and whether you are replacing one track or a pair. Compare the current Kubota U25-3 options and live pricing on TrackTECH rather than relying on a generic model estimate.
Should I replace worn tracks on a used Kubota U25-3?
If a used Kubota U25-3 has worn, cracked or damaged tracks, replacement can improve traction, ride quality, job readiness and how the machine presents at resale. Inspect the undercarriage condition at the same time so new tracks are not being installed over obviously worn components.
Can I buy undercarriage parts for the Kubota U25-3?
Yes. The current TrackTECH machine record lists these available part families for the Kubota U25-3: Sprockets, Idlers, Rollers. Availability and pricing are shown with the corresponding products.
