side of the cutter deck (2); remove the linch- pins on the left and right front side of the cut- ter deck (2); and remove the linchpins on the front of the mower (2).

f.Turn front caster wheels outward.

h.To install reverse the process.

2.Changing a Blade:

a.Remove the Key from the ignition and dis- connect the spark plug.

b.Jack up the front of the mowing deck about one foot and block it in that position.

c.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.

d.Use a 1-1/8" socket wrench on the pulley side of the spindle to secure.

e.Remove the hex nut using a 1-1/8" wrench.

f.Remove the hex nut.

g.To replace the blade reverse the above pro- cess and tighten nut to 100-120 lb-ft.

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 a Blade.

a.Set the parking brake.

b.Clean any debris from the blades. Keep blades sharp and free of build up at all times.

a.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 conven- tional electric grinder or a hand file to sharpen the blades.

b.Replace any blade with severe nicks or dents that cannot be removed by filing.

c.Check the balance of the blade after sharp- ening by placing it on a blade balancer. Do not use un-balanced blades.

d.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.

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 covers 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 pul- leys deflects the belt about 1/2".

5.Changing the Spindle Assembly

a.Jack up the front of the mowing deck about one foot and block it in that position.

b.Make sure the blade clutch is disengaged.

c.Remove the deck cover.

d.Remove the drive belts. (See 3. Changing Blade Drive Belts.)

e.Remove the cutter blade. (See 2. Changing a Blade.)

f.Using a wrench or socket rachet remove four hex nuts, and the four hex head cap screws. Remove the spindle assembly.

B.Hydraulic Oil

WARNING:

Never overfill the hydraulic units. Damage can occur if the oil level is not within the proper oper- ating 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.
