Adjusting The Height-Of-Cut; Adjusting The Rollers - Toro 30722 Operator's Manual

Adjusting the Height-of-Cut

The height of cut is adjustable from 25 to 102 mm (1 to
4 inches) in 13 mm (1/2 inch) increments, by adding or
removing an equal number of spacers from the front and
rear castor forks. The height-of-cut chart below gives the
combinations of spacers to use for all height-of-cut settings.
Height-of-Cut
Setting
25 mm (1 inch)
38 mm (1–1/2
inches)
51 mm (2 inches)
64 mm (2–1/2
inches)
76 mm (3 inches)
89 mm (3–1/2
inches)
102 mm (4 inches)
Note: A more optimum cutting appearance of the turf can
be achieved in the lower heights-of-cut by lowering the rear of
the cutting unit. Accomplish this by relocating the rear castor
wheel axles in the upper hole of the caster forks (Figure 14).
Place the axles into the lower castor fork holes for higher
height-of-cut settings where optimum cutting appearance is
not required.
Important: Do not attempt to cut off more than
25 mm (1 inch) of the grass blades in the 25 mm (1
inch) height-of-cut setting with the rear of the cutting
unit lowered, as this may cause the engine to labor
excessively.
1. Start the engine and raise the cutting unit so that the
front caster height-of-cut can be changed. Stop the
engine after the cutting unit is raised. The rear castor
height-of-cut can be changed with the cutting unit
lowered.
2. Remove the tensioning cap from the spindle shaft.
Slide the spacers onto the castor spindle to get the
desired height-of-cut (Fig. 18 and 19). Then slide the
washer (Figure 14) onto the spindle.
3. Push the castor spindle through the front castor arm,
install the other thrust washer and remaining spacers
onto the spindle, and install the tensioning cap to
secure the assembly (Figure 14).

Adjusting the Rollers

Note: If the cutting unit is to be used in the 25 or 38 mm
(1 or 1-1/2 inches) height-of-cut setting, the internal rollers
must be repositioned in the top bracket holes.
1. Remove the cotter pins securing the roller shafts to
the underside of the deck.
