Adjusting the Carrier Frame
(Groundsmaster 3500 only)
The front and rear cutting decks require different mounting
positions.
The front cutting deck has two mounting positions
depending on what height-of-cut and degree of deck
rotation is desired. The rear cutting deck has one mounting
position for proper alignment with the sidewinder under
frame.
Front Cutting Decks
1. For heights of cut in the 3/4 to 3 inch range, the front
carrier frames should be mounted in the lower front
mounting holes (Fig. 1).
Note: This permits more up travel of the cutting decks
relative to tractor when approaching quick uphill changes
in terrain. It does however limit the clearance of the
chamber to carrier when cresting sharp knolls.
2. For heights of cut in the 2–1/2 to 4 inch range, the front
carrier frames should be mounted in the upper front
mounting holes (Fig. 1).
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.
Rear Cutting Decks
For all heights of cut, the rear cutting deck should be
mounted in the rear mounting holes (Fig. 1).

Adjusting the Height of Cut
Important This cutting deck often cuts approximately
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 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 cutting deck to ground, stop engine, and remove
key from ignition switch.
2. Loosen capscrew securing each height of cut bracket to
height of cut plate (front and each side) (Fig. 2).
3. Beginning with front adjustment, remove capscrew.

4. While supporting chamber, remove spacer (Fig. 2).
5. Move chamber to desired height-of-cut and install
spacer into designated height-of-cut hole and slot
(Fig. 3).

6. Position tapped plate in line with spacer.
7. Install capscrew finger tight.
8. Repeat steps 4–7 for each side adjustment.
9. Tighten all three capscrews to 30 ft.-lb. (41 N⋅m).
Note: Adjustments of more than 1-1/2 inch may require
temporary assembly to an intermediate height to prevent
binding (e.g. changing from 1.25 in. to 2.75 in.
height-of-cut).
Adjusting the Roller Scraper
(Optional)
The optional rear roller scraper is designed to work best
when there is an even gap of .020–.040 inches between the
scraper and roller.
1. Loosen the top 2 mounting screws and the lower 2
flange nuts (Fig. 4).

is achieved between the rod and the roller.
3. Secure the mounting screws and flange nuts to 30 ft.-lb.
(41 N⋅m) in an alternating sequence.

8
Installing the Mulching Baffle
(Optional)
1. Thoroughly clean debris from mounting holes on rear
wall and left side wall of chamber.
2. Install mulching baffle in rear opening and secure with
5 flange head screws (Fig. 5).
1m–5421
Figure 5
1. Mulching baffle
3. Verify that mulching baffle does not interfere with
either tip of blade and does not protrude inside the
surface of the rear chamber wall.
Do not use the high lift blade with the mulching
baffle. The blade could break, resulting in personal
injury or death.

Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Operating Tips
Blade Selection
Standard Angled Sail
The blade generally performs best in lower heights of cut
(3/4 to 2–1/2 inch). The optional high lift parallel sail blade
performs better in the higher heights of cut (2 to 4 inch).
Attributes:
•Discharge remains more even at lower heights of
cut.
•Discharge has less tendency to throw left and thus a
cleaner look around bunkers and fairways.
•Lower power requirement at lower heights and
dense turf.
High Lift Parallel Sail
The blade generally performs better in the higher heights of
cut (2 to 4 inch).
Attributes:
•More lift and higher discharge velocity.
•Sparse or limp turf is picked up significantly at
higher heights of cut.
•Wet or sticky clippings are discharged more
efficiently reducing congestion in deck.
•Requires more horsepower to run.
•Tends to discharge further left and can tend to
windrow at lower heights of cut.
Do not use the high lift blade with the mulching
baffle. The blade could break, resulting in personal
injury or death.
Warning
Mow When Grass is Dry
Mow either in the late morning to avoid the dew, which
causes grass clumping, or in late afternoon to avoid the
damage that can be caused by direct sunlight on the
sensitive, freshly mowed grass.
Select the Proper Height-of-Cut Setting to
Suit Conditions
Remove approximately one inch or no more than 1/3 of the
grass blade when cutting. In exceptionally lush and dense
grass you may have to raise your height–of–cut setting
another notch.
Always Start Mowing with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases. Make sure
blade is in good condition and a full sail is present.
Check Condition of Deck
Make sure cutting chambers are in good condition.
Straighten any bends in chamber components to assure
correct blade tip/chamber clearance.
After Operating
To ensure optimum performance, clean underside of mower
housing. If residue is allowed to build up in mower
housing, cutting performance will decrease.
