SECTION 7:  SERVICE & ADJUSTMENTS
Replacing Drive Belt
Remove two shoulder screws securing the front 
drive cover to the mower deck. See Figure 11.
Figure 11
Press inward on the sides of the front drive cover 
and release the tabs that secure the front drive 
cover to the height adjuster brackets. Remove drive 
cover from the mower.
Using a torx wrench, loosen the screw holding the 
belt tension spring to the transmission. See Figure 
11
. Do not remove the screw completely. As you 
loosen the screw, tension on the belt will release. 
Push the transmission up a little and slide the belt 
off the transmission pulley.
Lift the mower to access the belt from the underside 
of the mower.
Slide the belt off the engine pulley and around the 
blade. See Figure 12 .
Replace with the new belt, working around the 
blade. Make sure the belt is firmly seated on the 
engine pulley while pulling from the other side and 
sliding it around the transmission pulley. 
Put the mower down with all four wheels firmly 
placed on one level. 
Tighten the screw, loosened earlier, to secure the 
belt tension spring to the transmission, and 
reassemble the front drive cover.

Replacing Rear Flap 
To remove rear flap, cut off the flat end of the wire 
rod which secures it to the deck. See Figure 13 . 
Attach the new flap and new rod to deck, bending 
the ends of the new rod over to secure to deck.

Adjusting Handle Height
Your mower is shipped with the handle in the higher 
height position. 
Remove the starter rope from the rope guide.
Remove the upper handle by removing the hand 
knobs and carriage bolts. Lay the upper handle out 
of the way, being careful not to bend or kink cables.
Remove the hairpin clips from the weld pins on the 
handle brackets. Refer to Figure 3 
Remove the carriage bolts and wing nuts from the 
handle brackets. Press out on the legs of the lower 
handle. Remove lower handle from the mower.
Turn the lower handle around so the notch on the 
bottom of the lower handle is facing forward as 
shown in Figure 14 . Reassemble, placing the 
bottom holes in the handle over the weld pins in the 
handle mounting bracket.
WARNING: 
Use a thick piece of rag to 
handle the blade while sliding the belt in the 
next step. Make sure the engine does not start 
at all while doing this job.
