FAQ

This drive belt fits John Deere lawn tractors including 105, 115, 125, 135, 145, D110, D120, D125, D130, D140, D150, D155, D160, D170, L105, L107, L108, L110, L111, L118, L120, L130, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, LA165, and LA175. It also fits X110, X120, X125, X126, X140, X145, X165, X166, X167, E170, and certain S-series tractors depending on the serial number. Because John Deere used this belt across multiple chassis and deck combinations, match your tractor model and serial number to the belt route in your parts diagram before ordering.
This belt replaces John Deere part numbers GX20006 and UC30568. It also cross-references with Husqvarna 532124525. Always verify by your original belt number or equipment parts diagram, as cross-references can vary by application.
GX20006 / UC30568 is the transmission or traction drive belt on John Deere riding mowers and lawn tractors. It transfers power to the transaxle to move the tractor. It is not the blade deck belt. If your tractor drives poorly, slips, or will not move consistently while the deck still spins, this is the correct belt to check.
Typical symptoms include slow or weak ground drive, slipping when climbing hills, delayed engagement when pressing the pedal, jerky movement, squealing from the drive system, or a tractor that will not move even though the engine runs normally. On inspection, the belt may appear glazed, cracked, frayed, stretched, or oil-soaked.
Installation is a moderate repair because the traction belt runs through the tractor drive system rather than just around the mower deck. On many John Deere lawn tractors, expect roughly 1 to 2 hours depending on the model and whether rust or packed debris slows disassembly. Common tools include socket wrenches, pliers, a belt-routing reference, and often a jack or ramps for access. Taking photos before removal helps, especially around idlers, guides, and keepers.
Check the idler pulleys, tensioner arm, pulley bearings, belt guides/keepers, transaxle pulley, and any spring that maintains belt tension. Also remove packed grass and debris from the drive area. A new belt can fail early or still slip if an idler bearing is rough, a pulley is bent, a keeper is rubbing, or the tensioner spring is weak.
The GX20006 / UC30568 belt is approximately 1/2 inch wide and 88.9 inches long, often rounded to 89 inches. Always prioritize the part number over the dimensions, as small specification differences can affect performance in tractor drive systems.
