How to Change the Drive Belt on a Craftsman Zts 7500 Riding Mower

The Craftsman ZTS 7500 is a zero turn lawnmower. This means, all four wheels pivot to allow the mower to spin on its axis. This allows for tight cornering and less trimming with a push mower. Although the deck rests below the engine, the deck itself still uses a pulley system and a drive belt to run the mower blades. Just as the belt on a lawn tractor wears out, the belt on the ZTS 7500 also wears out and requires replacement.

Instructions

- 1
  Position the mower blades to the "off" position and then place the speed levers into the "Park/Start" position. Turn off the mower and set the parking brake.
- 2
  Lower the deck on the ZTS 7500 to its lowest position with the height adjustment lever. This allows more room to work between the mower and the mower deck.
- 3
  Press the "Belt release" lever to release tension on the drive belt. The lever is located next to the pulley system on the mower deck.
- 4
  Locate the drive pulley under the engine and then pull the belt off the pulley by hand.
- 5
  Draw a detailed diagram of the pulleys and the belt routing. The drive belt has four pulleys and if you route the belt incorrectly, it causes the mower to function improperly.
- 6
  Remove the old belt and then place the new belt onto the pulleys.
- 7
  Stretch the belt and place it over the drive pulley mounted under the engine.
- 8
  Press the "Belt release" lever to tighten tension on the belt.
