FAQ

GX26422 is used on John Deere ZTrak zero-turn mowers, including models Z325E, Z330M, Z330R, Z355E, Z355R, Z365R, and Z375R. It is also compatible with select 48-inch, 48A, and 54-inch mower decks. Because deck configuration and serial breakpoints vary, always match the belt part number from your current belt or your machine's parts manual before ordering.
Compatibility depends on your specific deck setup. For the Z355E, this belt is designed for units with a 48-inch deck after serial number 060,001. If you own a Z355E or Z355R, verify your deck size and machine serial number to confirm this is the correct deck drive belt for your unit.
This belt is a direct replacement for John Deere part number GX26422. If your existing mower deck belt or your parts diagram specifies GX26422, this is the correct part.
Typical symptoms include blades failing to engage properly, weak or inconsistent cutting, a squealing sound during engagement, visible cracking or glazing, frayed edges, or the belt repeatedly slipping off the pulleys. On zero-turn mowers, a worn deck belt often results in uneven blade speed and poor cut quality, particularly in thick grass.
For most John Deere ZTrak owners, this is a moderate repair that takes approximately 30 to 90 minutes, depending on deck access and whether you choose to remove covers or lower the deck fully. Required tools typically include a socket set, ratchet, work gloves, and a breaker bar or belt tool to relieve spring tension on the idler. Always disconnect the spark plug leads and remove the ignition key before performing any maintenance on the deck.
Before installing the new belt, inspect the idler pulleys, spindle pulleys, belt keepers, tension spring, and deck bearings. A new belt will wear prematurely if a pulley is seized, misaligned, wobbling, or obstructed by debris. We recommend cleaning grass buildup from the deck and verifying the routing against your mower's belt diagram before starting the engine.
Premature failure is commonly caused by normal wear, heat buildup, improper tension, pulley misalignment, worn spindle or idler bearings, and debris accumulation in the belt path. Impact with heavy brush or operating with a damaged pulley can also significantly shorten belt life. If your previous belt failed suddenly or shredded, inspect the deck hardware thoroughly to ensure the replacement belt does not encounter the same issues.
