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).
Rear Cutting Decks
For all heights of cut, the rear cutting deck should be
mounted in the rear mounting holes (Fig. 1).
1

Figure 1
1. Front deck mounting hole (upper)
2. Front deck mounting hole (lower)
3. Rear deck mounting hole
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 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.

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).

Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
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.
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.
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.
• Requires more horsepower to run.
• Tends to discharge further left and can tend to
windrow at lower heights of cut.
Warning
Do not use the high lift blade with the mulching
baffle. The blade could break, resulting in personal
injury or death.

Maintenance
Note: Determine the left and right sides of the machine from the normal operating position.
Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do any
maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
Greasing the Bearings
Each cutting deck has two grease fittings per spindle. Either
fitting can be used, which ever is more accessible. If
machine is operated under normal conditions, lubricate
blade spindle bearings (Fig. 6) with No. 2 general purpose
lithium base grease or molybdenum base grease, after every
50 hours of operation. Pump grease into fitting until a small
amount appears at bottom of spindle housing (under deck).
4. Release latch rod (Fig. 7) from front carrier frame

Adjusting the Blade Plane
Removing the Cutter Blade
Start with front adjustment (change one bracket at a time).
1. Remove height-of-cut bracket, (front, left, or right)
from deck frame (Fig. 11).
2. Adjust .060 in. shims and/or .030 in. shim between the
deck frame and bracket to achieve the desired height
setting (Fig. 11).

Figure 11
1. Height of cut bracket 2. Shims
3. Install height-of-cut bracket to deck frame with
remaining shims assembled below the height-of-cut
bracket.
4. Secure socket head bolt/spacer and flange nut.
Note: Socket head bolt/spacer are held together with
Loctite to prevent spacer from falling inside the deck
frame.
The blade must be replaced if a solid object is hit, the blade
is out of balance or if the blade is bent. Always use genuine
Toro replacement blades to be sure of safety and optimum
performance. Never use replacement blades made by other
manufacturers because they could be dangerous.
1. Raise cutting deck to highest position, shut the engine
off, and engage the parking brake. Block cutting deck to
prevent it from falling accidentally.
2. Grasp end of blade using a rag or thickly padded glove.
Remove blade bolt, anti-scalp cup, and blade from
spindle shaft (Fig. 12).

3. Install blade, sail facing toward cutting deck, with
anti-scalp cup and blade bolt (Fig. 12). Tighten blade
bolt to 85–110 ft.-lb. (115–149 N⋅m).
Danger
5. Verify 12 o’clock height and adjust if needed.
6. Determine if only one or both (right-hand and left-hand)
height-of-cut brackets need to be adjusted. If the 3 or 9
o’clock side is .150±.030 in. higher than the new front
height then no adjustment is needed for that side. Adjust
other side to within ±.030 in. of correct side.
7. Adjust right and/or left height-of-cut brackets by
repeating steps 1 thru 3.
8. Secure carriage bolts and flange nuts.
9. Again, verify 12, 3, and 9 o’clock heights.
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator’s or
bystander’s area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Never weld a broken or cracked blade.
• Always replace a worn or damaged blade.
13
Page 14
Inspecting and Sharpening the
Blade
1. Raise cutting deck to highest position, shut the engine
off, and engage the parking brake. Block cutting deck to
prevent it from falling accidentally. On the
Groundsmaster 3500, secure cutting deck service latch.
2. Examine cutting ends of the blade carefully, especially
where the flat and curved parts of the blade meet
(Fig. 13-A). Since sand and abrasive material can wear
away the metal that connects the flat and curved parts of
the blade, check the blade before using the machine. If
wear is noticed (Fig. 13-B), replace the blade; refer to
Removing the Cutter Blade, page 13.
Danger
SHARPEN AT THIS
ANGLE ONLY
END VIEW
Figure 14
4. To check blade for being straight and parallel, lay blade
on a level surface and check its ends. Ends of blade
must be slightly lower than the center, and cutting edge
must be lower than the heel of the blade. This blade will
produce good quality of cut and require minimal power
from the engine. By contrast a blade that is higher at the
ends than the center, or if cutting edge is higher than the
heel, the blade is bent or warped and must be replaced.
If the blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Fig. 13-C). eventually a piece of the blade may
break off and be thrown from under the housing,
possibly resulting in serious injury to yourself or
bystanders.
• Inspect the blade periodically for wear or
damage.
• Always replace a worn or damaged blade.
5. Install blade, sail facing toward cutting deck, with
anti-scalp cup and blade bolt. Tighten blade bolt to
85–110 ft.-lb. (115–149 N⋅m).
Blade Stopping Time
The blades of the cutting deck are to come to a complete
stop in approximately 5 seconds after the cutting deck
engagement switch is shut down.
Note: Make sure the decks are lowered onto a clean section
of turf or hard surface to avoid thrown dust and debris.
To verify this stopping time, have a second person stand
back from the deck at least 20 feet and watch the blades on
one of the cutting decks. Have the operator shut the cutting
decks down and record the time it takes for the blades to
come to a complete stop. If this time is greater than 7
seconds, the braking valve needs adjustment. Call your
Toro Distributor for assistance in making this adjustment.
Servicing the Rear Roller
After every 800 hours or annually, the cutting unit
roller assemblies must be dis–assembled, inspected,
re–greased and re–assembled. Roller seals should be
replaced and bearings should be inspected and replaced
if necessary.
Figure 13
3. Inspect cutting edges of all blades. Sharpen the cutting
edges if they are dull or nicked. Sharpen only the top of
the cutting edge and maintain the original cutting angle
to make sure of sharpness (Fig. 14). The blade will
remain balanced if same amount of metal is removed
from both cutting edges.
Disassembly
1. Remove mounting screws and nuts securing the scraper
to roller mounts (Fig. 15). Remove scraper and plates.
2. Remove mounting screws securing roller mounts to rear
of deck frame (Fig. 15). Remove roller mounts.
3. Remove the lower screws securing each end of roller to
roller mounts (Fig. 15).

Neither The Toro Company nor Toro Warranty Company is
liable for indirect, incidental or consequential damages in
connection with the use of the Toro Products covered by this
warranty, including any cost or expense of providing substitute equipment or service during reasonable periods of

below, if applicable, there is no other express warranty. All
implied warranties of merchantability and fitness for use are

System on your Product may be covered by a separate warranty
meeting requirements established by the U.S. Environmental
