New Holland E50B Rubber Tracks

Replacement rubber tracks for the New Holland E50B mini excavator in 400x72.5Nx74 — 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 New Holland E50B

  • 400x72.5Nx74 — 400 mm tread width (about 16"), 72.5 mm pitch, 74 links, narrow 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.

Undercarriage parts for the New Holland E50B

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:

Same track, other machines

Track size follows undercarriage geometry, not brand, so 400x72.5Nx74 shows up on machines from several makers. If you run any of these alongside the New Holland E50B, it is the same belt:

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.

    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.
