Using a 3⁄8” socket breaker bar or socket ratchet insert the 

drive end into the 3⁄8” square opening in the lower idler arm 

assembly and push the idler arm counterclockwise. See 

Figure 1-4. While holding the idler arm back, loosen the deck 

belt from the pulley and slide the belt away from the pulley.

Remove the blade drive belt from all the pulleys.

5. 

Reverse the process to install the belt. See Figure 1-5 for 

proper belt routing.

NOTE: When replacing belts do not overtighten. Adjust 

the idler pulley so that a ten-pound pull with a spring scale 

between two pulleys deflects the belt about 1⁄2”.

Before performing any maintenance, 

place the PTO switch in the “OFF” position, engage the 

parking brake lever, turn the ignition key to the “OFF” 

position and remove the key from the switch. Protect 

your hands by using heavy gloves when handling the 

blades. When servicing the mower  deck, be careful 

not to cut yourself on the sharpened blades.

Remove key from the ignition and disconnect the spark plug.

2. 

Jack up the front of the mowing deck about one foot and 

block it in that position.

3. 

Wrap a rag around one end of the blade and grasp it to prevent 

it from turning, or secure the blade by placing a block of wood 

between the blade and the deck housing. See Figure 1-6.
