2. To lower the front of the deck, loosen the outer nut then
loosen (thread outward) the nut, away from the front
hanger bracket. See Figure 6-6. When proper adjustment is
achieved, re-tighten the outer nut.
Leveling the Deck (Side-to-Side)
If the cutting deck appears to be mowing unevenly, a side to side
adjustment can be performed. Adjust if necessary as follows:
1. With the tractor parked on a firm, level surface, place the
deck lift lever in the middle position and rotate both blades
so that they are perpendicular with the tractor.
2. Measure the distance from the outside of the left blade
tip to the ground and the distance from the outside of the
right blade tip to the ground. Both measurements taken
should be equal. If they're not, proceed to the next step.
3. Under the rear fenders inside the wheels there is a lift
adjustment rod for each side of the deck. See Figure 6-7.
Figure 6-7
4. Minor side-to-side adjustments should be made using
primarily the left adjustment rod.
5. To raise the left side of the deck, loosen the upper nut on the
end of the lift rod, then turn the lower nut clockwise. When
the proper adjustment is achieved, tighten the upper nut to
secure in place. To lower the left side of the deck, loosen the
upper nut on the end of the lift rod, then turn the lower nut
counterclockwise. When the proper adjustment is achieved,
tighten the upper nut to 25-30 ft-lbs. to secure in place.
6. The deck is properly leveled when both blade tip
measurements taken earlier are equal.
Adjusting the Deck Height
The height of the deck can be adjusted to ensure that the setting
on your deck height lever is accurate. To adjust the deck height
proceed as follows:
1. Park the tractor on a firm, level surface and place the deck
lift lever in the highest position (4") and rotate the blade
nearest the discharge chute so that it is perpendicular with
the tractor.
2. Measure the distance from the outside of the left blade
tip to the ground and the distance from the outside of the
right blade tip to the ground. Both measurements taken
should be 4". If they're not, proceed to the next step.
3. Using the right and left lift rods, raise or lower the
necessary side of the deck until both sides are measured at
4" from the pavement.
Adjusting the Deck Wheels
WARNING!:
Keep hands and feet away from the
discharge opening of the cutting deck.
NOTE: The deck wheels are an anti-scalp feature of the deck and
are not designed to support the weight of the cutting deck.
The deck wheels should be approximately 1⁄4-1⁄2" above the
ground when the deck is set in the desired height setting. To
adjust the deck wheels see the Assembly & Set-Up section for
instructions.
Seat Adjustment
Refer to the Assembly & Set-Up section of this manual for seat
adjustment instructions.
WARNING!
Before operating the tractor, make
sure the seat is engaged in the seat-stop. Engage the
parking brake. Stand behind the machine and pull
back on seat until it clicks into place.
Parking Brake Adjustment
If the tractor does not come to a complete stop when the brake
pedal is completely depressed, or if the tractor's rear wheels
can roll with the parking brake applied (and the hydrostatic
relief valve open), the brake is in need of adjustment. See your
authorized dealer to have the brake adjusted.
Wheel Alignment
If your tractor pulls to one side or is out of alignment, a wheel
alignment might be necessary. Take your tractor to an authorized
service dealer to have the wheels properly aligned.
