Mini-excavator track fitment can be more sensitive than a generic make/model lookup suggests. For the Kubota U55-5, TrackTECH's current live catalog lists the following replacement-track configuration:
Kubota U55-5 rubber track size
- 400x72.5Wx74
Match width, pitch, link count and guide family. If the machine has more than one cataloged option, verify the actual undercarriage rather than choosing the closest-looking belt.
How to verify the existing track
- Read the molded size on the old track.
- Confirm width, pitch and link count.
- Note any N, W or other guide designation.
- If the marking is gone, measure the belt and compare the guide geometry.
See How to Measure Rubber Tracks and Rubber Track Guide Types Explained.
Inspect the undercarriage before installing new rubber
- Check sprocket teeth for hooking and uneven wear.
- Inspect rollers and idlers for play, leakage and flat spots.
- Check the tensioner and grease adjuster for normal travel.
- Clean packed debris from the track frame before installation.

Frequently asked questions
Can I order by model only?
Sometimes, but when multiple configurations exist the installed track and guide family should be checked before shipment.
Should both tracks be replaced?
If both are similarly worn, replacing the pair is usually the cleaner mechanical choice. See Should You Replace Rubber Tracks in Pairs?.
Quick Buying Answers
Which rubber track rides the smoothest? For a verified fitment that offers it, Multi-Bar is usually the first tread to compare when lower vibration and smoother travel matter most.
Which track lasts longest on pavement? On asphalt and other hard, relatively flat surfaces, Multi-Bar is a strong first choice because it spreads contact across more tread bars. For harsher abrasive work such as broken concrete, rock, or demolition debris, compare a heavier C-Block or Staggered Block pattern instead.
What is the best track for paving? Start with Multi-Bar when ride quality, steady contact, and hard-surface travel are priorities. Confirm that the exact pattern is available for your machine before ordering.
What is the most affordable track? Price depends on the exact width, pitch, link count, guide type, and tread. Once fitment is confirmed, compare the live compatible options rather than changing dimensions just to save money.
What about mud, snow, or soft ground? Zig-Zag is usually the better pattern to compare when cleanout and bite matter more than pavement manners.
