The John Deere 333G track is listed as 450 x 86 x 58B (450 mm wide, 86 mm pitch, 58 links) in a C-lug, D-lug or Z-lug tread. This guide covers how to confirm the fit, the signs of wear and the 333G sprockets and bottom rollers to check.
Ordering new tracks for a John Deere 333G starts with the size. Our catalog lists one track size for this machine, in three tread patterns. This guide gives the John Deere 333G track size, how to confirm the fit, the signs that tracks are worn and the 333G sprockets and bottom rollers worth checking while the tracks are off.
The short answer
Our catalog lists one track size for the John Deere 333G. The width, pitch and link count are fixed. Only the tread pattern changes.
| Track size | Width | Pitch | Links | Tread |
|---|---|---|---|---|
| 450 x 86 x 58B | 450 mm (17.7 in) | 86 mm | 58 | C-lug, D-lug or Z-lug |

Read the size as width x pitch x links. If your old track shows a different width, pitch or link count, check with us before you order.
Our 333G parts page holds two track listings. One is titled John Deere 333G and is listed with a C-lug tread. The other is titled John Deere CT333G and is listed with a C-lug, D-lug or Z-lug tread. Both are listed under the 333G model in our catalog, and both show the same size, 450 x 86 x 58B.
Before you order, check the model on the machine’s plate. If it shows something other than 333G or CT333G, or you are not sure, contact us with the serial number and we will check.
If the size is still readable on your old track, use it. If it has worn away, take three measurements:
Width
Measure across the track from edge to edge. A 333G track should measure 450 mm (17.7 in).
Pitch
Measure from the center of one link to the center of the next. The 333G track has an 86 mm pitch.
Links
Count the drive lugs around the inside of the track. The 333G track has 58.
If your numbers read 450, 86 and 58, you have the right size. Our guide to measuring rubber tracks shows each step with diagrams.
Match the size
Compare the size on the old track, or your measurements, with the table above. If any figure differs, stop and check before you order.
Confirm the model
Read the model and serial number from the machine’s plate. Our 333G parts page includes listings titled 333G and CT333G. If the plate shows anything else, contact us before you order.
Choose the tread
Choose a C-lug, D-lug or Z-lug tread to suit the ground and the work. If you want to keep the tread the machine has now, send us a photo of the old track.
Look underneath first
Before the new tracks go on, inspect the sprockets, idlers and bottom rollers. New tracks on a worn undercarriage wear out sooner.
Our advice
A size that is checked, not guessed, is the quickest way back to work. If anything does not match, talk to the team before you order, so you maximize machine uptime and avoid a return.
These are the checks we recommend on any tracked machine, and they apply to the 333G.
If the track keeps going slack after you adjust it, do not assume the track is the cause. A track adjuster with failed piston seals cannot hold tension, and worn sprockets can add to the problem. Here is how to check rubber track tension. The correct track tension figure for the 333G is in your machine’s operator’s manual.
When sprocket teeth wear sharp, they stop holding the track cleanly. The track can slip or jump through the sprocket, and the shock load travels into the final drive. If you see or hear this happen, stop and inspect the sprockets before you carry on.
If tracks wear out well before the last set did, check the parts underneath before you fit new ones. Material packing between sprocket teeth, rollers and the track also speeds up wear, so keep the undercarriage clean. Our guide to spotting a worn sprocket shows what to look for, and these five tips to extend rubber track life cover other common causes.
Spinning the tracks, unnecessary reversing, high travel speed when it is not needed and always turning in the same direction all add wear. They wear the tracks and the sprockets that drive them.
With the tracks off, the whole undercarriage is in plain view. That makes a track change the best time to inspect it. Here is what our catalog lists for the 333G:
| Part | Per machine | Weight each |
|---|---|---|
| Drive sprocket | 2 | 20.5 kg (45.2 lb) |
| Bottom roller | 10 | 28.7 kg (63.3 lb) |
| Idler | Not listed online | Ask the team |

The sprocket bolts to the final drive and its teeth engage the track to drive the machine. Our catalog lists 2 per 333G. Sprocket wear is hard to judge by eye, so compare yours with an unused sprocket of the same type. Wear builds faster in reverse and at higher travel speeds.
Bottom rollers run along the underside of the track frame and carry the machine’s weight on the track. Our catalog lists 10 per 333G. Look for flat spots, worn flanges, oil leaks and rollers that no longer turn. We advise changing bottom rollers as a set, because a single new roller sits proud of the worn ones and wears faster. Our guide to bottom rollers and carrier rollers explains the difference.
Idlers guide the track around each end of the track frame and work with the track adjuster to hold tension. Check for worn running surfaces, damaged flanges and oil leaks. We do not currently list a 333G idler online, so contact us with the serial number if yours is worn. With an idler off, it is also the easiest time to check or replace the track adjuster.
Our advice
If the sprockets, idlers or rollers show wear, replace them with the tracks. It is one job and one round of downtime, and the new tracks start on a sound undercarriage.
These are the 333G parts in our catalog. All four are on the John Deere 333G parts page.

Our catalog lists the 450 x 86 x 58B track for the 333G in C-lug, D-lug and Z-lug treads. The listing titled 333G is C-lug. The listing titled CT333G offers all three.
Some of the listings on our 333G parts page are titled CT333G. In our catalog they are listed under the 333G model, and the tracks show the same size. If your model plate or paperwork shows something different, contact us with the serial number before you order.
Yes. We sell 333G tracks individually, and the price shown is for one track.
Our catalog lists 10 bottom rollers per 333G machine. We advise changing them as a set.
We do not currently list a 333G idler online. Contact us with your machine details and serial number and the team will check what we can supply.
Common signs are a track that will not hold tension, a track that slips or jumps on the sprocket, and tracks that wear out much faster than the last set. Check the parts underneath at the same time, because worn parts shorten the life of new tracks.
