•
Use the deck lift handle of the tractor to lower the
deck lift arms into the slots of the rear deck
hanger brackets.
•
Pull the deck support pins outward and maneuver
the deck as necessary to align the holes in the
deck lift arm with the pins. Refer to Figure 26.
•
When aligned, push each pin fully inward through
the lift arms to secure the arms in the rear hanger
bracket slots.
•
Route the 'V' belt rearward beneath the tractor
frame and install the belt in the pulley of the PTO
clutch.
•
Route the backside of the belt around the fixed
idler pulley of the deck. Refer to Figure 25.
•
Insert a 1/2 inch ratchet into the square hole of
the deck idler bracket. Refer to Figure 25.
•
Using the ratchet for leverage, pivot the idler
bracket rearward against the spring tension and
slide the backside of the belt onto the movable
idler pulley. Refer to Figure 25.
LEVELING THE MOWER DECK
When leveled correctly the mower deck should be
level side to side, and should be approximately a 1/8
to 1/4 inch lower in the front of the deck.
Side to Side Leveling
If the cutting deck appears to be mowing unevenly, a
side to side adjustment can be performed. Adjust if
necessary as follows:
•
With the tractor parked on a firm, level surface,
place the deck lift handle in the top notch (highest
position) and rotate both blades so that they are
perpendicular to the tractor frame.
•
Measure the distance from the outside left blade
tip to the ground and the distance from the
outside right blade tip to the ground. The
measurements should be equal. If they're not,
proceed to the next step.
•
Compare the two measurements as follows:
- Model ZT42—determine whether the right side
of the deck must be raised or lowered.
- Model ZT50—determine whether the left side
of the deck must be raised or lowered.
•
