Deck Installation

To install the mower deck, proceed as follows:
1. While holding the deck front hanger rod upward, carefully
slide the deck underneath the right side of the tractor.
2. While still holding the front hanger rod, slide the deck
forward until the front hanger rod can be lowered into the
slots of the front deck bracket.
3. Lower the front hanger rod into the slots of the front deck
bracket, then slide the deck rearward.
4. Maneuver the deck so that the slots in the two rear deck
hanger brackets approximately align with the deck lift arms
of the tractor. Refer to Fig. 7-5.
5. Use the tractor deck lift handle to lower the deck lift arms
into the slots of the rear deck hanger brackets.
6. Pull the deck support pins outward and maneuver the deck
as necessary to align the holes in the deck lift arms with the
pins. Refer to Fig. 7-5.
7. When aligned, push each pin fully inward through the lift
arms to secure the arms in the rear hanger bracket slots.
8. Make certain the 'V' belt is in the spindle pulleys on the
deck; then route the belt rearward beneath the tractor
frame, above the transmission tube(s), to the PTO pulley on
the bottom of the engine.
9. Install the 'V' belt onto the PTO pulley using one of the
following two methods.
WARNING!
may be extremely hot, and could cause serious burns.
Use extreme caution when near the muffler. Allow
the muffler to fully cool before installing the belt.
Using the Idler Pulley to Tension the Belt.
1. Using the deck lift handle, raise the deck to the position that
provides the most horizontal run of the belt between the deck
idler pulleys and the PTO pulley on the bottom of the engine.
2. Install the belt in the PTO pulley on the bottom of the engine.
3. Route the backside of the belt around the fixed idler pulley
of the deck. Refer to Fig. 7-3.
4. Working from the middle of the tractor, pivot the idler
bracket/movable pulley rearward against the spring
tension and slide the backside of the belt onto the movable
idler pulley. Refer to Fig. 7-3.
Rolling the Belt into the PTO Pulley.
1. Using the deck lift handle, raise the deck to the position that
provides the most horizontal run of the belt between the deck
idler pulleys and the PTO pulley on the bottom of the engine.
2. Make certain the belt is in the spindle pulleys of the deck,
and that the backside of the belt is against both the fixed
and movable idler pulleys. Refer to Fig. 7-3.
3. Sitting behind the tractor, facing forward, make certain the
belt is not twisted; then reach beneath the tractor to grasp

Mower Blade Care
WARNING!
Before performing any maintenance,
place the PTO switch in the "OFF" position, engage the
parking brake lever, turn the ignition key to the "OFF"
position and remove the key from the switch. Protect
your hands by using heavy gloves when handling the
blades. When servicing the mower deck, be careful not
to cut yourself on the sharpened blades.
The cutting blades must be kept sharp at all times. Sharpen the
cutting edges of the blades evenly so that the blades remain
balanced and the same angle of sharpness is maintained.
If the cutting edge of a blade has already been sharpened many
times, or if any metal separation is present, it is recommended
that new blades be installed. New blades are available at your
authorized dealer.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor, (refer to Deck
Removal on page 29) then gently flip the deck over to
expose its underside.
