The John Deere 35G runs a 300x52.5Nx86 rubber track — 300 mm wide, 52.5 mm pitch, 86 links, narrow (N) guide lug profile. If you're replacing tracks on a 35G, that's the number that matters. Everything else in this guide supports it: how to confirm the size on your machine, what a replacement actually costs, and which undercarriage parts wear out alongside the rubber.
John Deere 35G Track Size
| Track size | 300x52.5Nx86 |
| Width | 300 mm (12") |
| Pitch | 52.5 mm |
| Links | 86 |
| Tread pattern | Directional |
| Track weight | ~307 lb each |
The "N" in 300x52.5Nx86 matters. It designates the narrow guide-lug profile that matches the 35G's undercarriage geometry. A 300x52.5x86 track with the wrong lug profile will not seat correctly on your rollers — when ordering from any supplier, confirm the full designation, not just the three numbers.

John Deere 35G Specs
| Class | 3.5-ton mini excavator |
| Engine | 24 HP diesel |
| Operating weight | 7,800 lb |
| Bucket dig force | 8,200 lb |
| Dig depth | 11'2" |
| Aux hydraulic flow | 10.6 GPM |
| System pressure | 3,336 PSI |
| Tail swing | Zero tail swing |
Zero tail swing and 7,800 lb of machine working tight against foundations is exactly the duty cycle that eats tracks — constant counter-rotation on abrasive ground. Plan on the lower end of track life if the 35G lives on gravel and rock.
How to verify the size on your machine
- Read the existing track. The size is molded into the rubber on the inside or outside face — look for 300x52.5x86 or 300x52.5Nx86.
- Measure it. Width across the track face (300 mm), distance between two link centers (52.5 mm), and count the links around the loop (86). Our measuring guide walks through it with photos.
- Call it in. (850) 816-7898 — give us your serial number and we'll verify fitment before anything ships.
What replacement tracks cost
A heavy-duty aftermarket 300x52.5Nx86 track for the 35G runs about $920 per track from TrackTECH — continuous steel cord construction, directional tread, 24-month warranty, free freight to the lower 48. Dealer OEM pricing for the same size typically lands well above that per side. Most owners replace in pairs: mismatched wear between sides accelerates wear on the new track and pulls the machine off line on slopes.
35G undercarriage parts (with part numbers)
If your tracks are worn, inspect the rest of the undercarriage while the machine is up. These are the 35G part numbers we stock:
- Drive sprocket — #1032265: check for hooked or sharpened teeth. A worn sprocket chews up a new track fast.
- Front idler — #9269094: look for flange wear and wobble.
- Bottom roller — #4340535: the highest-wear item under the machine. Spin each one; any that won't turn or leak oil are done.
- Top roller — #4718355: supports the track's return run; flat spots cause track slap.
Replacing tracks on a worn sprocket is the most common money-wasting mistake we see. The sprocket is a fraction of the cost of the tracks it destroys.
Same size, different machine?
The 35G shares its 300x52.5Nx86 track with the John Deere 30G. Other G-series minis run different sizes — don't cross them over:
- 17G — 230x48x70
- 26G — 300x52.5Nx80 (same width and pitch, fewer links — not interchangeable)
- 50G — 400x72.5Nx74
- 60G — 400x72.5Wx74
Browse every size in the 300x52.5Nx86 collection or all John Deere rubber tracks and undercarriage parts.
When to replace 35G tracks
- Lug depth under ~50% — traction drops noticeably in mud and on slopes
- Exposed or rusting steel cord — the track is structurally compromised; failure tends to come without much more warning
- Cracking between lugs — normal aging past ~1,500–2,000 hours depending on ground conditions
- Repeated de-tracking — usually stretch; if tensioning doesn't hold, the cords have elongated
FAQ
What size rubber track does a John Deere 35G use?
300x52.5Nx86 — 300 mm wide, 52.5 mm pitch, 86 links, narrow guide lug.
Are 30G and 35G tracks interchangeable?
Yes — both machines run 300x52.5Nx86.
How much does a John Deere 35G weigh?
About 7,800 lb operating weight — a 3.5-ton class zero-tail-swing mini excavator.
How long do 35G rubber tracks last?
Typically 1,200–2,000 hours depending on surface. Dirt and turf are easy on rubber; gravel, rock, and demolition debris cut life significantly.
Should I replace both tracks at once?
In almost all cases, yes. A new track paired with a half-worn one wears unevenly and affects tracking.
