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".
4.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. Chang- ing 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 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.

1.Adding Hydraulic Oil (use SAE20W 50)
a.Place the Mower on a level surface and engage the parking brake.
b.Stop the engine and remove the key from the ignition switch.
c.Clean the area around the Hydraulic Oil fill neck.
d.Remove the hydraulic fill cap and check the level. The correct level is up to the low- est hole of the oil tank fill neck.
e.Pour hydraulic oil into the reservoir up to the lowest hole in the oil tank fill neck, if necessary.
2.Draining Hydraulic Oil
Used hydraulic oil must be disposed of properly. Do not pour it down a drain or sewer, or dump it on open land, this creates an environmental hazard. Please be aware of the environment when disposing of used oil.
a.Place the Mower on a level surface and engage the parking brake.
b.Stop the engine and remove the key from the ignition switch.
c.Remove the mower deck. See section on Mower Deck.
d.Raise the seat forward to expose the hydraulic oil fill point.
e.Clean the area around the hydraulic fill oil cap.
f.Remove hydraulic fill oil cap.
g.Place a suitable container (at least 2 gal- lon) under the hydraulic reservoir and filter.
h.Remove the hydraulic filter to allow hydrau- lic oil to drain. Remove the drain plug from the bottom of the hydraulic oil tank to drain. Replace the plug.
i.Place a small pan under the pump motor frame. Remove fill oil cap from hydraulic reservoir for faster drainage. Remove nut
