Toro 30072, Operator'S Manual, Page: 35 / 44

Important:
The sail part of the blade must be
pointing upward, toward the inside of the mower
to ensure proper cutting (Figure 43).
2. Install the blade stiffener, flat washer and blade bolt
(Figure 43).
3. Torque the blade bolt to 85-110 ft-lb (115-140 N-m).
Correcting the Mower Quality
of Cut
Note:
Tire air pressure is critical in these procedures.
Make sure all tires have correct pressure.
If one side of the mower cuts lower than the other,
correct it as follows:
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Adjust the tire pressure in the traction unit tires to
specifications.
4. Check that the blades are not bent; refer to Checking
for a Bent Blade.
5. Set the height-of-cut to the 2-1/2 inch (64 mm)
position; refer to Adjusting the Height-of-Cut.
6. Ensure that the mower support rods are resting on
the frame cushions.
Checking the Mower Deck Front-to-Rear
Pitch
1. Check the tire pressure on both deck and traction
unit.
2. Position one blade front-to-rear (Figure 46). Measure
at C and D locations from a level surface to the
cutting edge of the blade tips (Figure 46).
3. The mower should be 1/8 to 5/8 inch (3 to 16 mm)
lower at C than in the rear at D .

4. If an adjustment is necessary, move an equal number
of thrust washers on both castor wheel forks. Move
the thrust washers from the top of the carrier frame
mounting tube to the bottom to raise the front of the
mower. Move the thrust washers from the bottom
of the mounting tube to the top to lower the front
of the mower (Figure 47).
5. Check the side-to-side setting of the mower deck.
