Leveling The Mower From Side-To-Side; Adjusting The Front-To-Rear Blade Slope - Toro 74701 Operator's Manual

Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 35).
Important
The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the stiffener and blade bolt (Fig. 35). Torque the
blade bolt to 80–100 ft.-lb. (108–136 N m).
Leveling the Mower from
Side-to-Side
The mower blades must be level from side to side. Check
the side-to-side level any time you install the mower or
when you see an uneven cut on your lawn.
1. Position the mower on a flat surface. Disengage the
PTO, set the parking brake, stop the engine, and remove
the key. Disconnect the spark plug wire(s) from the
spark plug(s).
2. Check the air pressure of all four tires. If needed, adjust
to the recommended inflation; refer to Tire Pressure,
page 28.
3. Set the height-of-cut at 3 inch (76 mm).
4. Carefully rotate the blade(s) from side to side (Fig. 38).
Measure between the outside cutting edges and the flat
surface (Fig. 38). If both measurements are not within
3/16 inch (4.75 mm), an adjustment is required; refer to
steps 5 and 6.

5. Remove the hairpin cotter and washer from the leveling
bracket (Fig. 39). To level the blade(s), reposition the
leveling bracket(s) in a different hole and install the
washer and hairpin cotter (Fig. 39). A front hole lowers
the blade height and a rear hole raises its height. Adjust
both sides as required.
6. Check the front-to-rear blade slope; refer to Adjusting
the Front-to-Rear Blade Slope, page 30.

Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade level any time you install the
mower. If the front of the mower is more than 5/16 inch
(7.9 mm) lower than the rear of the mower, adjust the blade
level using the following instructions:
1. Position the mower on a flat surface. Disengage the
PTO, set the parking brake, stop the engine, and remove
the key. Disconnect the spark plug wire(s) from the
spark plug(s).
2. Check the air pressure of all four tires. If needed, adjust
to the recommended inflation; refer to Tire Pressure,
page 28.
3. Check and adjust the side-to-side blade level if you
have not checked the setting; refer to Leveling the
Mower from Side-to-Side, page 30.
