Replacing the Blades

Warning! 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.

1.Remove the key from the ignition and disconnect the spark plugs.

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 Fig. 7-6.

Figure 7-5

6.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”.

Figure 7-6

4. Use a 1-1⁄8” socket wrench on the pulley side of the spindle bolt.

5. Remove the hex nut at the blade using a 1-1⁄8” wrench.

6. Remove the blade.

7. To replace the blade reverse the above process and tighten nut to 100-120 lb ft.

NOTE: Add a small amount of multi-purpose grease to the bolt threads to avoid corrosion and galvenic action.

WARNING! Never mow with dull blades. Blades that are bent should be replaced. The cutting blades are sharp and can cause severe injury. Wrap the cutting surface of the blade with a rag to avoid injury.
