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".

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. Chang-
ing a Blade.)

f.

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

g.

Reverse the process to install the spindle 
assembly.

B.Hydrostatic Dive System

1.

Your zero turn riding mower is equipped with 
dual integrated hydrostatic pumps, motors, and 
planetary gear reduction transaxles that are 
sealed and do not require service, maintenance, 
or adjustments.

C.Electrical Circuit

Danger:

Read General Safety Precautions Nos. 9 and 10.

1.

Battery: The battery is located beneath the 
operator’s seat. If so equipped, remove the 
fillcaps and check the level of the liquid elec-
trolyte in the battery every 50 operating hours. 
If the level in any of the six cells has dropped 
below the bottom of the split ring inside the fill 
hole, refill the cell with distilled water. To keep 
the outside of the battery clean, brush on a 
strong solution of bicarbonate of soda and 
water and rinse with clean water. Keep the 
contacts and cable ends clean with a wire 
brush and make sure the connections are 
tight. Coat the terminals with petroleum jelly 
to prevent corrosion.

2.

Battery Removal

Warning:

When removing the cables from the battery 

follow these steps to avoid a short between 
the wrench and the frame.

a. Remove the negative (black) cable.
b.

Remove the positive (red) cable.

c.

Release the hold down straps.

d. Remove the battery without tipping.

3.

Battery Storage: When storing the mower for 
long periods of time the following guidelines 
should be performed.

a.

Disconnect the battery cables from the ter-
minals and remove the battery.

b.

Clean the battery before storing. A dirty 
battery will lose its charge over time.
