Adjusting Height-Of-Cut - Toro 30140 Operator's Manual

Danger
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in place,
you and others are exposed to blade contact and
thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
Never put your hands or feet under the mower.
Never try to clear discharge area or mower
blades unless you release the bail and the power
take off (PTO) is off. Also pull the wire off the
spark plug(s).

Adjusting Height-of-Cut

This machine has a 1 to 4-1/4 inch (26 to 108 mm) range
for height-of-cut. This can be achieved by adjusting blade
spacers, rear axle height and front caster spacers. Use the
Height-of-Cut chart on page 24 to select the combination
required
Adjusting the Blade Height
Blades are adjusted by using the four, 1/4 inch (6 mm)
spacers found on the blade spindle bolts. This allows a
range, in 1/4 inch (6 mm) increments, of cutting height in
any axle position. The same number of blade spacers must
be used on all blades to achieve a level cut (two above and
two below, one above and three below, etc.).
1. Stop engine and remove spark plug wire(s).
2. Hold blade bolt and remove nut. Slide bolt down,
through spindle, and change spacers as required
(Fig. 23).
3. Insert bolt, add extra spacer(s), and secure with thin
washer and nut (Fig. 23).
4. Torque blade bolt to 75–80 ft–lb (101–108 N m).

Adjusting the Axle Height
Desired height-of-cut range can be obtained by adjusting
the rear axle and placing caster spacers above or below the
caster arm (see chart).
1. Stop engine and remove spark plug wire(s).
2. Loosen but do not remove the 2 axle pivot bolts and the
2 axle adjustment bolts (Fig. 24).
3. Place a jack under the rear center of the engine frame.
Raise the back end of the engine frame up enough to
remove front 2 axle adjustment bolts (Fig. 24).
4. Raise or lower the engine frame with the jack, so that
front 2 axle adjustment bolts can be installed in the
desired hole location (Fig. 24). A tapered punch can be
used to help align the holes.
5. Tighten all 4 bolts and lower the unit.
6. Adjust control rods and brake linkages as required.
Refer to Servicing the Brake on page 32 and Installing
the Traction Control Rod on page 15.
Important It will be necessary to adjust control rods
and brake linkage when changing axle positions for proper
traction and brake function.
