IMPORTANT:The V-belts found on your tractor are
specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not
disengaging completely. For a proper working machine,
use factory approved belts.

proceed as follows:
NOTE: It is recommended that both drive belts be
replaced at the same time.
Remove the upper drive belt from around the
transmission pulley and the variable-speed pulley.

the belt off it.
