Replacement rubber tracks for the Wacker Neuson ST50 compact track loader in 450x86x58 — 450 mm wide, 86 mm pitch, 58 links. Built for grading, loading, pallet work and land clearing, with free freight to the lower 48.
What the numbers mean on a Wacker Neuson ST50
- 450x86x58 — 450 mm tread width (about 18"), 86 mm pitch, 58 links
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 Wacker Neuson ST50
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- All-Terrain — everything in between. A compromise tread when the machine moves between surfaces
- Staggered Block — mixed dirt and gravel. Block stability with better cleanout than a straight block
- C-Block — concrete, asphalt and hard-packed ground. Longest wear life and the least vibration on hard surfaces
- Multi-Bar — mud, snow and soft ground. Deep bar lugs bite and shed material instead of packing up
- X-Terrain — the worst ground you have. Aggressive lugs for mud, slope and loose fill
- Z-Max — soft and slippery ground. An aggressive zig-zag with more bite
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 Wacker Neuson ST50
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:
- Front idler — 7240006
- Rear idler — 275574
- Undercarriage kit
How these wear
CTLs run high ground speed and counter-rotate all day, which is what eats edge lugs and drive lugs first. 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.
