Toro 74601 - Tire Pressure; Leveling the Mower from Side-To-Side

30
Tire Pressure
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every 50
operating hours or monthly, whichever occurs first
(Fig. 35). Check the tires when they are cold to get the most
accurate pressure reading.
Rear Tires: 13 psi (90 kPa)
Front Tires (castor wheels): 35 psi (139 kPa)

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 30.
3. Set the height-of-cut at 3 in. (76 mm).
4. Carefully rotate the blade(s) from side to side (Fig. 36).
Measure between the outside cutting edges and the flat
surface (Fig. 36). If both measurements are not within
3/16 in. (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. 37). To level the blade(s), reposition the
leveling bracket(s) in a different hole and install the
washer and hairpin cotter. (Fig. 37). A front hole lowers
the blade height and a rear hole raises its height. Adjust
both sides as required.
