Adjusting The Height Of Cut; Checking The Interlock Switches - Toro Groundsmaster 4500-D Operator's Manual

Adjusting the Height of Cut

Important:
The cutting units often cut
approximately 6 mm (1/4 inch) lower than a reel
cutting unit with the same bench setting. It
may be necessary to set the cutting-unit bench
measurement at 6 mm (1/4 inch) above that of reel
cutting units cutting in the same area.
Important:
Access to the rear cutting units is
greatly improved by removing the cutting unit
from the machine.
1. Park the machine on a level surface, engage
the parking brake, lower the cutting unit to the
ground, shut off the engine, and remove the key.
2. Loosen the bolt securing each height-of-cut
bracket to the height-of-cut plate (front and each
side) as shown in

bolt.

9. Torque all 3 bolts to 41 N∙m (30 ft-lb). Always
tighten the front bolt first.
Note:
Adjustments of more than 3.8 cm (1-1/2
inches) may require temporary assembly to an
intermediate height to prevent binding (e.g.,
changing from 3.1 to 7 cm (1-1/4 to 2-3/4 inches)
height of cut).
