When to Replace

  • Visible cracks, fraying, or splitting along the belt sidewalls.
  • Noticeable slippage during mower operation or difficulty engaging the blades.
  • The belt has stretched beyond the adjustment capacity of the mower tensioning system.
  • Glazing on the underside of the belt caused by excessive friction.

Installation Tips

  • Disconnect the spark plug wire before beginning any maintenance to ensure safety.
  • Consult your owner's manual for the specific belt routing diagram, as improper routing will cause premature wear.
  • Ensure the tensioning pulley moves freely and the spring has adequate tension before installing the new belt.
  • After installation, run the mower at a low speed for several minutes to allow the belt to seat properly in the pulleys.

FAQ

This belt is specifically designed for John Deere ZTrak 737 and 757 mid-mount zero-turn mowers. It also cross-references with various equipment from brands including Exmark, Ariens, Dixie Chopper, Encore, King Kutter, and MTD.
In addition to the John Deere TCU16907, this belt replaces Exmark part numbers 1-403174, 403174, 1-323722, and 1-403174-SL. It is also compatible with Stens 265-636 and Oregon 15-009.
This is an HB-section belt measuring 0.67 inches in width and 115.3 inches in effective length. It is constructed with aramid cord for high-tensile strength and resistance to stretching under heavy loads.
You should inspect your belt if you notice visible fraying, cracking, or glazing on the underside. Performance-wise, look for slipping during engagement, a burning rubber smell during operation, or a loss of power to the mower deck or drive system.
Before installing the new belt, inspect all idler pulleys and spindle sheaves for debris, rust, or bearing play. Ensure the pulleys spin freely and are properly aligned. If a pulley is seized or wobbling, it will cause the new belt to fail prematurely.
Replacing the drive belt on a ZTrak 737 or 757 is a moderate task that typically takes 30 to 60 minutes. You will generally need a socket set and a breaker bar or a dedicated belt tensioner tool to release the tension on the idler arm. Always consult your machine's service manual for the specific routing diagram to ensure the belt is correctly seated on the jackshaft assembly and spindle sheaves.
