Park unit on a flat surface. Stop engine and remove
ignition key. Make sure blade engagement switch is
in the down (OFF) position. Spread both control
levers fully apart and set Park Brake Lever (ON).

WARNING
Make sure engine and engine muffler is completely cooled
before working on and around the drive belt. Severe burns to
the body could result if engine and muffler have not cooled.

Remove deck drive belt (#3 in Figure 5-19) from the
deck drive pulley (#2) as outlined in “Deck Drive
Belt Removal & Installation” on Page 47. This belt

pulleys (#8) and onto the ground drive pulley (#2).

pulleys.
