What the numbers mean on a Mustang 2109
- 450x86x63 — 450 mm tread width (about 18"), 86 mm pitch, 63 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 Mustang 2109
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- 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
- Z-Max — soft and slippery ground. An aggressive zig-zag with more bite
- Zig-Zag — general mixed ground. Balanced traction with a smoother ride than a bar 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 Mustang 2109
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:
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.
Same track, other machines
Track size follows undercarriage geometry, not brand, so 450x86x63 shows up on machines from several makers. If you run any of these alongside the Mustang 2109, it is the same belt:
- CAT 272C
- Case TV620B
- Gehl 7600
- Gehl 7800
- Gehl 7810
- Mustang 2095
- Mustang 2099
- Mustang 2105
- New Holland C362
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.
