Deck belt installation

NOTE: For ease in installing the deck belt, 
refer to the routing decal on bottom of seat.

Wrap the deck belt around the electric 
clutch pulley that is located on the engine 
shaft.

Route the belt forward between the EZT 
(E-Series Zeroturn Transaxles) and up 
onto the deck.

Place belt around spring loaded

 

idler 

pulley, between the pulley and guide. 
Secure bolt and nut.

Starting on the right hand side of the 
deck, wrap the belt around the stationary 
idler pulley, the right mandrel housing, 
then around to the left mandrel housing.

Push inward on the idler arm and 
carefully route belt over stationary idler 
pulley. Once belt is properly routed, 
slowly release idler arm to tension belt.

Double check belt routing to make sure it 
matches the routing decal, and the belt 
does not have any twist. Correct as 
needed.

Replace belt shields on both mandrel

 

housings and secure with fasteners.
