•
If the timing belt was installed correctly and the timing
arrows were positioned as shown in Figure 7-5, the cut-
ting blades should be in the position shown in Figure
7-6.
•
Reinstall the PTO belt onto the RH spindle drive pulley
and re-install the deck as described in "Re-installing the
Cutting Deck" below.
Reinstalling the Cutting Deck
There are two methods for reinstalling the mower deck
on the tractor. One method involves rotating the PTO belt
idler bracket to relieve enough belt tension to allow the
belt to be placed in either the PTO pulley or the fixed idler
pulley. Because that method is difficult, we recommend
using the second method of rolling the belt onto the PTO
pulley.
Install the cutting deck as follows:
•
From the right side of the tractor, slide the deck under
the tractor and align the rear deck hanger brackets with
the deck lift arms.
•
Slide the deck forward and place the deck front hanger
rod into the slots of the deck front hanger bracket. Then
slide the deck rearward so that the front hanger rod is
at the front of the slots.
•
Using the deck lift lever, lower the deck lift arms. From
either side of the tractor, pull the support pin in the
deck rear hanger bracket outward, align the deck lift
arm hole with the deck support pin and release the pin
so that it goes through the deck lift arm. Repeat on the
other side of the tractor to secure the deck.
•
After first making sure the deck belt is properly
engaged in all of the deck pulleys, route the deck belt
forward through the center of the front deck hanger
rod and toward the PTO pulley on the bottom of the
engine.
•
Using the deck lift handle, raise the deck to the posi-
tion that gives you the most horizontal run of the belt
between the deck pulleys and the PTO pulley on the
bottom of the engine.
•
Sitting in front of the tractor, facing rearward, make
certain the belt is not twisted; then reach beneath the
tractor to grasp the belt and pull it toward the PTO
pulley.

NOTE: References to left and right are from the front of the
tractor in the following instructions.
•
Pull the right side of the belt forward and place the nar-
row V side of the belt into the PTO pulley.
•
While holding the belt and pulley together, rotate the
pulley to the left. Continue holding and rotating the
pulley and belt until the belt is fully rolled into the PTO
pulley. See Figure 7-7.

WARNING: Use caution to prevent pinching
your fingers when rolling the belt onto the PTO
pulley.
Checking the Cutting Blade Timing
During normal operation the timing of the cutting blades
can be altered by abnormal loads on one, or both, cutting
blades. Regularly check the timing arrows on the spindle
assemblies to make certain they are 90° from each other.
If the timing arrows are not 90° from each other, proceed
as follows:
•
Remove the deck from the tractor. Remove the idler
bracket backstop. Refer to Figure 7-4.
•
Pivot the idler bracket/idler pulley to relieve the tension
on the timing belt, and reposition the drive pulley
and/or timing pulley to achieve the 90° orientation of
the timing arrows.
•
Re-install the idler bracket backstop and position so
that there is a 1/8" gap between the backstop and idler
bracket. Tighten the hex screw and flange lock nut to
secure in the adjusted position.
