Section 5: Maintenance & Lubrication
Belt Maintenance
Refer to Figure 5-17 and Figure 5-18 on page 43:
Replace belts that show signs of severe cuts, tears,
excessive weather checking and cracking or burns
caused by slipping. Slight raveling of belt covering does
not indicate belt damage. Trim ravelings with a sharp
knife.
Inspect belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against
the bottom of the groove. Replace pulley when this is the
case, otherwise belt will lose power and slip excessively.
Never pry a belt onto a pulley as this will cut or damage
the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition
in a very short time.
Deck Drive Belt Removal & Installation
Refer to Figure 5-17 on page 43:
1. Park mower on a flat surface.
2. Make sure blade engagement switch is (OFF),
control levers are fully (OUT), park brake is (ON) and
engine switch key is (OFF) and removed.
3. Place deck height in the lowest position.
4. Remove deck belt covers and raise floor panel.
5. Pull hitch pin (#11).
6. Release deck belt tension by putting a 3/4" socket
wrench on the over-center-release bolt (#10) and
turning counterclockwise. This will relieve the
tension on the tension idler spring (#6).
7. Pull tension idler (#5) to the left of the machine to
provide maximum belt clearance.
8. Remove existing deck drive belt (#3).
9. Route new deck drive belt (#3) as shown in
Figure 5-17.
10. Re-tension the tension idler (#5) by turning the
over-center-release bolt (#10) clockwise. Check belt
tension per the "Deck Drive Belt Adjustment" on
page 26.
11. Re-install hitch pin (#11).
12. Re-install deck belt covers and lower floor panel.

WARNING
Make sure engine and engine muffler is completely cooled
before working on and around the drive belt. Severe burns to
the body could result if engine and muffler have not cooled.
3. Place deck height in the lowest position.
4. Remove deck drive belt (#3) from deck drive pulley
(#1) as outlined in "Deck Drive Belt Removal &
Installation" instructions on this page. This belt does
not need to be removed from any of the deck pulleys
shown in Figure 5-17.
5. Release tension on ground drive belt (#4) by pulling
on pump idler arm (#6) and carefully removing belt
from pump tension idler (#5). Use caution when
releasing idler arm as pump idler spring (#7) is in
tension and will snap the arm back into position.
6. Slide ground drive belt (#4) off the two pump
pulleys (#8) and remove from mower.
7. Slide new belt over pump pulleys (#8) and ground
drive pulley (#2).
8. Pull on pump idler arm (#6) and slide belt onto pump
tension idler (#5). Make certain to keep fingers
from getting between the belt and the pulley
when pulley is released and tension is
re-established.
9. Re-install deck drive belt (#3) on deck drive
pulley (#1). Make sure the belt is routed properly on
all deck pulleys.
10. Re-tension deck belt idler per the "Deck Drive Belt
