Troy-Bilt HYDROSTATIC LAWN TRACTOR - HORSE 769-06304 - Manual (Page 21)

Balance the deck by using a wrench to turn the adjustment 4.
gear (found immediately behind the hex cap screw just
loosened) clockwise/up or counterclockwise/down.
The deck is properly balanced when both blade tip
measurements taken earlier are equal.
Retighten the hex cap screw on the left deck hanger
5.
bracket when proper adjustment is achieved.
Seat Adjustment
Refer to the Set-Up and Assembly section of this manual for seat
adjustment instructions.
Parking Brake Adjustment
WARNING! Never attempt to adjust the brakes
while the engine is running. Always disengage PTO,
move shift lever into neutral position, stop engine
and remove key to prevent unintended starting.
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, the brake is in need of
adjustment. See an authorized Troybilt Service Dealer to have
your brakes properly adjusted.
Front To Rear
The front of the cutting deck is supported by a stabilizer bar that
can be adjusted to level the deck from front to rear. The front of
the deck should be between ¼-inch and 3⁄8-inch lower than the
rear of the deck. Adjust if necessary as follows:
With the tractor parked on a firm, level surface, place the 1.
lever for lifting the platform on the second to the top notch
(second highest position) and rotate the blade as close to
the discharge channel that is parallel to the tractor.
Measure the distance from the front of the blade tip to
2.
the ground and the rear of the blade tip to the ground.
The first measurement taken should be between ¼” and
3⁄8” less than the second measurement. Determine the
approximate distance necessary for proper adjustment and
proceed, if necessary, to the next step.
Locate the jam nut and lock nut on the front side of the
3.
stabilizer bracket. See Fig. 6-3 After loosening the jam nut:
Tighten the lock nut to raise the front of the deck;
Loosen the lock nut to lower the front of the deck.
Retighten the jam nut loosened earlier when proper 4.
adjustment is achieved.
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:
With the tractor parked on a firm, level surface, place the 1.
deck lift lever in the second from the top notch (second
highest position) and rotate both blades so that they are
perpendicular with the tractor.
Measure the distance from the outside of the left blade
2.
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.
Loosen, but do NOT remove, the hex cap screw on the left
3.
deck hanger bracket. See Fig. 6-4.
