Cub Cadet Fabricated Deck InDirect Injection Diesel Hydraulic Oil, Changing the Blade Drive Belts

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 un-balanced blades.

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- anced—REPLACE.

3.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.Remove tension of the PTO belt by moving the belt tensioning rod. Loosen the belt retaining bolt.

d.Using a 1/2" socket breaker bar or socket rachet insert the male end into the 1/2" opening in the lower idler arm assembly and pull the idler arm clockwise. While holding the idler arm back, loosen the blade drive belt from the pulley and slide the belt away from the pulley.

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".

B.Hydraulic Oil

WARNING:

Never overfill the hydraulic units. Damage can occur if the oil level is not within the proper operating range.

Note: When adding hydraulic oil, do so in small quantities and recheck the oil level before adding more. It is important that you do not overfill the reservoir to allow for fluid expansion.
