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.
3.Sharpening the Blade:
a.Set the parking brake.
b.Clean any debris from the blades. Keep blades sharp and free of build up at all times.
c.Sharpen blades evenly at the original 30° angle to maintain balanced cutting blades. Do not sharpen the underside of the blades. Use a electric blade sharpener, a conventional electric grinder or a hand file to sharpen the blades.
d.Replace any blade with severe nicks or dents that cannot be removed by filing.
e.Check the balance of the blade after sharpening by placing it on a blade bal- ancer. Do not use
f.If the blade dips on one end, file stock off of the cutting surface on that end.
Note: Blades that cannot be easily bal-
4.Changing the Blade Drive Belts:
a.Set the parking brake. Remove ignition key and both spark plug caps.
b.Unscrew the wing nuts from the deck cov- ers and remove both covers.
c.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 counter- clockwise. While holding the idler arm back, loosen the blade drive belt from the pulley and slide the belt away from the pul- ley.
d.Remove tension of the PTO belt by moving the belt tensioning rod. Loosen the belt retaining bolt.
e.Pull the tensioner pulley away from the belt and remove the PTO belt then remove the blade drive belt.
f.Reverse the process to install the belt.
Note: When replacing belts do not over- tighten. Adjust the idler pulley so that a ten- pound pull with a spring scale between two pulleys deflects the belt about 1/2".
