Adjusting The Height-Of-Cut - Toro 30807 Operator's Manual

2. Front deck mounting hole
(lower)
2. For heights of cut in the 6.3 to 10 cm (2-1/2 to 4 inch)
range, mount the front carrier frames in the upper
front mounting holes (Figure 16).
Note: This increases the chamber to carrier clearance
due to the higher position of the cutting chamber, but
will cause the cutting deck to reach their maximum up
travel sooner.
Adjusting the Rear Cutting Deck
The front and rear cutting decks require different mounting
positions. The rear cutting deck has one mounting position
for proper alignment with the sidewinder under frame.
For all heights of cut, mount the rear cutting deck in the rear
mounting holes (Figure 16).

Adjusting the Height-of-Cut

No Parts Required
Procedure
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

4. While supporting the chamber, remove the spacer
(Figure 17).
5. Move the chamber to the desired height-of-cut and
install a spacer into the designated height-of-cut hole
and slot (Figure 18).
6. Position the tapped plate in line with the spacer.
7. Install the bolt finger tight.
8. Repeat steps 4-7 for each side adjustment.
9. Tighten all three 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 (1.25 to 2.75 inch) height-of-cut).
