John Deere 30G Rubber Tracks & Parts

Q: What size rubber tracks fit a John Deere 30G?

The John Deere 30G can use 300x52.5x86 rubber tracks. Match the full size on the track you are replacing before you order. If your machine has more than one track setup, choose the width and guide style that matches the track currently on the machine.

The John Deere 30G runs a 300x52.5Nx86 track: 300 mm across the tread, 52.5 mm between links, 86 links around. Cut for digging, trenching, backfill and tight-quarters work and shipped free to the lower 48.

What the numbers mean on a John Deere 30G

300x52.5Nx86 — 300 mm tread width (about 12"), 52.5 mm pitch, 86 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.

Tread choice for the John Deere 30G

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

Undercarriage parts for the John Deere 30G

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:

Drive sprocket — 1032265
Front idler — 9269094
Bottom roller — 4340535
Carrier roller — 4718355

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 300x52.5Nx86 shows up on machines from several makers. If you run any of these alongside the John Deere 30G, 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.

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.
