2.
Usea 15A6" wrench to hold the hex nut on top of the spindle
assembly when loosening the hex nut securing the blade.
A block of wood may be placed between the deck housing
and the cutting edge of the blade to help in breaking loose
the hex nut securing the blade. See Fig. 7-7.

When reinstalling the blades, be sure they are installed so that
the wings are pointing upward toward the top of the deck.
4.
Tighten the blade nuts to 70-90 ft. Ibs.
5.
Reinstall the deck (refer to Deck Installation on page 28).
Transmission DriveBelt
If the transmission drive belt becomes worn and causes the drive
transmissions to slip, the drive belt must be replaced. To replace
the drive belt, proceed as follows:
1.
Remove the deck drive belt from the PTOclutch on the bottom
of the engine following the instructions in Deck Removal.
2.
From beneath the rear of the tractor, insert a %" drive ratchet
into the square hole of the drive idler bracket. SeeFig. 7-8.

3.
Using the ratchet for leverage, pivot the idler bracket and idler
pulley away from the backside of the 'V" belt; then lift the belt
offand above the engine pulley and offthe idler pulley.
4.
With the belt loose, lift the belt off, up and over the two
transmission drive pulleys. Remove the belt from the
engine and idler pulleys.
5.
Loop the new belt and slide over and onto the two
transmission pulleys.
6.
Route the belt above the idler bracket back to the engine
drive pulley. Lift the belt over the PTOpulley and above the
engine drive pulley.
7.
Using the ratchet for leverage, pivot the idler bracket and
idler pulley against the spring tension; then slip the belt
down into the engine drive pulley and onto the idler pulley.
8.
Releasethe idler bracket so that the idler pulley tightens
against the back side of the belt and tensions the drive belt.
9.
Reinstall the deck drive belt.
TractorCreeping
Creeping
is the slight forward
or backward
movement
of the
tractor when the engine is running
at high idle and the drive
control
levers are opened
out in the neutral
position.
If after operating
the tractor for some time, it begins to creep
while in the neutral
position,
adjust the transmission
control
rods
as follows.
1.
Place the front of the tractor
against an immovable
object
(e.g. wall, post, etc.).
2.
Jack up the rear of the tractor so that both rear wheels are
approximately
one inch of the ground.
3.
With the engine
running
at high idle and the drive control
levers opened
out in the neutral
position,
and the parking
brake disengaged,
check the rear wheels for rotation.
4.
If only one wheel
is rotating,
locate the transmission
control
rod beneath
the frame at the front of the rear tire. If
both wheels rotate, locate both control
rods. See Fig. 7-9.
