About Thomas Equipment
Thomas compact equipment is used every day across construction, landscaping, snow removal, and agriculture. UltraTrack stocks aftermarket rubber tracks and undercarriage parts verified to fit 27+ Thomas models, built to the same dimensional specifications as the originals.
Track size varies by model and frame class, which is why selecting by exact model number is critical. Use the size chart below to match your machine, or our Parts Finder to confirm the precise track for your Thomas unit.
Thomas undercarriages use a standard sprocket, idler, and roller layout. When replacing tracks it pays to inspect the sprocket teeth and roller condition — worn drive components shorten the life of a new set of tracks.

Thomas OEM Tracks vs Ultra Track Aftermarket
OEM Thomas rubber tracks purchased through a dealer carry premium pricing and a standard parts warranty of around 12 months.
Ultra Track aftermarket rubber tracks for Thomas machines are built to the same dimensional specifications and use equivalent construction: continuous steel cord belting, virgin rubber compounds, and drop-forged steel links — at well below dealer pricing and backed by a 30-month warranty, more than double standard OEM coverage.
Both deliver the same fitment, ground-pressure distribution, and traction. Service life is comparable when the aftermarket track uses continuous wound cords and virgin rubber, which Ultra Track tracks do.
Maintaining Your Thomas Rubber Tracks
Track Tension
Check track tension at the start of every operating day. Typical sag on a compact track loader is about 1 to 1.5 inches at the midpoint between the front idler and rear sprocket — always confirm the exact figure in your Thomas operator's manual.
Undercarriage Cleaning
Packed material adds weight, raises fuel burn, and causes uneven wear. Hose out the undercarriage at the end of each day, especially in clay or wet soil.
When to Replace
Replace tracks when you see cracking between lugs deeper than 1/4 inch, exposed steel cords, uneven lug height, or slipping on the sprocket despite correct tension. Quality aftermarket tracks average 1,200 to 2,000 hours.
Replace Undercarriage Components Together
Sprockets often wear faster than tracks on machines run hard on abrasive surfaces. Inspect sprocket teeth, idler bearings, and rollers when installing new tracks.

Are aftermarket rubber tracks as good as Thomas OEM tracks?
Quality aftermarket tracks built with continuous wound steel cords and virgin rubber compounds deliver comparable fitment and service life to OEM. The main difference is cost.
