Correcting The Mower Quality-Of-Cut - Toro 74568TE Operator's Manual

Note: If the blade stays in a horizontal position, the
blade is balanced and can be used.
1. Blade
3. If the blade is not balanced, file some metal off the end
of the sail area only (Figure 79).
4. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft (Figure 82).
Important: The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt (Figure 82).
Note: The spring-disk cone must be installed toward
the bolt head (Figure 82).
3. Torque the blade bolt to 115 to 150 N-m (85 to
110 ft-lb).

Correcting the Mower
Quality-of-Cut
If one deck blade cuts lower than the other, correct it as
follows:
Note: Tire air pressure is critical in these procedures; make
sure the rear tires have the correct pressure.
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. Disconnect the spark plug wire(s) from the spark
plug(s).
4. Adjust the tire pressure in the rear tires to 83 to 97 kPa
(12 to 14 psi).
5. Check that the blades and spindle shafts are not bent;
refer to Checking for Bent Blades (page 54).
6. Set the height-of-cut to the 7.6 cm (3 inches) position;
refer to Adjusting the Height-of-Cut (page 25).
Checking the Mower Deck Side-to-Side
Height
1. Adjust the rear-tire pressure.
2. Ensure that the blades are not bent; refer to Checking
for Bent Blades (page 54).
3. Position the blades side-to-side.
4. Measure at the B and C locations from a level surface
to the cutting edge of blade tips (Figure 83).
1. Measure from a level
surface
5. The difference between measurements B and C should
be no more than 6 mm (1/4 inch).
Note: If it is not correct, refer to Changing the Mower
Deck Side-to-Side Height (page 56).
