Adjusting The Height Of Cut; Checking The Interlock Switches - Toro Groundsmaster 4300-D Operator's Manual

Adjusting the Height of Cut

Important:
This cutting deck often cuts
approximately 6 mm (1/4 inch) lower than a reel
cutting unit with the same bench setting. It may
be necessary to have these rotary cutting deck's
bench set 6 mm (1/4 inch) above that of reels
cutting in the same area.
Important:
Access to the rear cutting units is
greatly improved by removing the cutting unit
from the tractor. If the unit is equipped with a
Sidewinder®, sidewind the cutting units to the
right, remove the rear cutting unit, and slide it out
to the right side.
1. Lower the cutting deck to the ground, shut off the
engine, and remove the key from ignition switch.
2. Loosen the bolt securing each height-of-cut
bracket to the height-of-cut plate (front and each
side) as shown in

inches) may require temporary assembly to an
intermediate height to prevent binding (e.g.,
changing from 3.1 to 7 cm (1.25 to 2.75 inches)
height of cut).
