Maintenance - Troy-Bilt J609 Operator's Manual

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 top notch (highest 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 not, proceed
to the next step.
3. Loosen, but do not remove, the hex cap screw on the
left deck hanger bracket. See Figure 9.
4. To balance the deck turn the adjustment gear,
located immediately behind the hex cap screw,
clockwise/up or counterclockwise/down. See Figure 9. You will need an adjustable wrench for this step.
5. The deck is properly balanced when both blade tip measurements, taken earlier, are equal.
6. Retighten the hex cap screw on the left deck hanger bracket when proper adjustment is achieved.
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. The brake disc can be
found on the right side of the transmission in the rear of
the tractor. Adjust if necessary as follows:
1. Looking at the transmission from the right side of the
tractor, locate the compression spring and brake disc.
See Figure 10.
2. Loosen, but do not remove, the hex nut found on the
right side of the brake assembly. See Figure 10.
3. Using a feeler gauge, set the gap between the brake
disc and the brake puck at .011".
4. Re-tighten the hex nut loosened earlier.
