Set-Up Instructions

ADJUST THE TURF
COMPENSATION SPRING
The turf compensation spring (Fig. 5), connecting the
carrier frame to the cutting unit controls the amount of
fore-aft rotation available, and the amount of ground
clearance in transport and turn around.
The turf compensation spring also transfers weight from
the front to the rear roller. This helps reduce a wave
pattern in the turf.
IMPORTANT: Make spring adjustments with the
cutting unit mounted to the traction unit and lowered
to the shop floor. Refer to the traction unit operator’s
manual for mounting instructions.
1. Tighten the lock nut on the rear of the spring rod
until the gap (C) between the rear of the spring
bracket and front of the washer is 1/2” (13 mm)
(Fig. 5).
2. Tighten the hex nuts on the front end of the spring
rod until the compressed length (A) of the spring is
8” (203 mm) (Fig. 5).
NOTE: When cutting rough or undulating turf,
increase the compressed length (A) of the spring to
B=1/2” (216 mm) and the gap (C) between the rear
of the spring bracket and the front of the washer to
1-1/4” (32 mm) (Fig. 5).
NOTE: As the compressed spring length (A)
DECREASES, weight transfer from the front roller
to the rear roller INCREASES and the carrier
frame/cutting unit rotation angle (B) DECREASES.
NOTE: As the gap (C) between the spring bracket
and washer INCREASES, cutting unit ground
clearance DECREASES and the carrier
frame/cutting unit rotation angle (B) INCREASES.

IMPORTANT. To insure proper setting of height of
cut, these procedures must be followed in this order:
A. Adjusting (Parallel) the bedknife to the reel
B. Setting cutting unit attitude
C. Leveling the front roller
D. Finalizing height of cut
IMPORTANT: Each cutting unit must be set
consistently. Minor differences in either 1) height of
cut, 2) attitude, 3) bedknife wear or 4) Reel blade
wear, between cutting units, may result in negative
after-cut appearance.
NOTE: The cutting unit has been set at the factory at
1.59 cm (5/8”) height of cut and with a cutting unit
attitude of 2 degrees. Also, the bedknife has been
retracted from the reel to prevent shipping damage.
Verity the setting to ensure changes did not occur during
shipment.
A. ADJUSTING (PARALLEL) THE BEDKNIFE
TO THE REEL
IMPORTANT. The reel and bedknife must be
parallel to an even cut of grass, and that the reel and
bedknife wear evenly.
NOTE: Toro recommends light contact between the reel
and bedknife. However, for dry and/or sparse conditions
a .001–.002” (.03–05 mm) clearance may be required to
prevent heat buildup, which can cause uneven wear in
the reel and bedknife.
NOTE: A 3/4-inch (19 mm) wrench is needed to rotate
the bedknife adjustment knob. Each notch on the knob
will move the bedknife 0.0005 inches (.013 mm) closer
to the reel (Fig. 6).
1. Rotate the cutting unit backward to gain access to
reel and bedknife (Fig. 7).
2. While slowly rotating the reel in the mowing
direction, turn the bedknife adjusting knob
clockwise until you hear light contact between the
reel and bedknife.
Figure 6
1. Bedknife adjusting knob
3. Insert a 3-cm wide piece of newspaper
perpendicular to the bedknife, and then turn the reel
slowly in the mowing direction to see if the reel
cuts the paperódo this on both ends of the bedknife
(Fig. 7).
Figure 7
4. If paper is cut on both ends, the bedknife is parallel
to the reel. If not go to steps 5 through 8.
NOTE: If the reel makes contact on both sides of
the bedknife but still does not cut paper, the cutting
unit may need to be backlapped (refer to
Backlapping) and/or reel and bedknife may need to
be reground (refer to Toro manual for Sharpening
Reel and Rotary Mowers, Form No. 80-30OPT).

4. Bottom adjusting nut
5. Loosen the pivot hub lock nuts to allow
movement of the pivot hub (Fig. 8).
6. If the paper was not cut on the left side: loosen
the bottom adjusting nut on the pivot hub, then
turn the top adjusting nut clockwise to pull the
pivot hub up. OR If paper was not cut on the right
side: loosen the top adjusting nut on the pivot hub,
then turn the bottom adjusting nut counterclockwise
to push the pivot hub down (Fig. 8).
NOTE: To reduce thread play, always tighten the
bottom adjusting nut last.
7. Recheck the reel-to-bedknife contact on both ends
of the bedknife, and repeat step 6 as necessary.
NOTE: Reel-to-bedknife contact may become too
tight or too loose after the previous adjustment,
therefore, turn the bedknife adjustment knob,
accordingly, for lighter contact.
8. Retighten the pivot hub lock nuts.
NOTE: Recheck whether the paper still cuts on
both ends of the reel to insure the bedknife did not
move when tightening the pivot hub lock nuts.
B. SETTING CUTTING UNIT ATTITUDE
IMPORTANT: Cutting unit “attitude” has a
significant impact on the performance of the cutting
unit. Attitude refers to the angle of the knife relative
to the ground (Fig. 8). Adjustable front and rear
brackets allow for variable adjustment of the cutting
unit attitude within the height-of-cut range. All
cutting units on a machine must be set to the same
attitude. If they arenít, the after-cut appearance will
be negatively affected.
Figure 9
1. Attitude
The best cutting unit attitude depends on your turf
conditions and desired results. Experience with the
cutting unit on your turf will determine the best setting
to use. Cutting unit attitude can be adjusted throughout
the cutting season to allow for various turf conditions.
In general, less aggressive attitudes (example: 2 degrees)
are more appropriate for warm season grasses while cool
season grasses may require more aggressive attitudes
(example: 6 degrees). More aggressive attitudes cut more
grass off by allowing the spinning reel to pull more grass
up into the bedknife. An angle that is too flat (attitude
less than 1 degree) may allow the bedbar or other parts
of the cutting unit to drag in the turf causing tufting.
Therefore, minimum recommended attitude is 1 degree.
For setting consistent cutting unit attitude, Toro strongly
recommends using a two-screw gauge bar, Toro part no.

SETTING ATTITUDE FOR NEW CUTTING
UNITS:
Table 1 lists dimensions for setting up a new cutting unit
with attitudes of 2, 4, 6 and 8 degrees.
NOTE: The second screw setting will change
throughout the life of the bedknife and reel due to wear
even if the height of cut is not changed. Therefore, after
initial set up use Checking and Adjusting Attitude for
Used Cutting Unit procedure.
1. Using a two-screw gauge bar, Toro part no. 98-
1852, set the first screw to the desired height of cut.
This setting is from the bar face to the underside of
the screw head (Fig. 10).
2. Set the front bracket height “B” using the
approximate dimension given by Table 1. This
measurement is between the bottom surface of the
middle casting and the top surface of the rod casting
(Fig. 11).
Figure 11
3. Set the rear support bracket and side plate using the
approximate dimensions given by Table 1. The rear
support bracket is either in the top or bottom
location, and the side plate location can be in holes
1 through 4, with 1 being the top hole (Fig. 12).
Figure 12
1. Rear support bracket
2. Side plate holes
4. With the cutting unit rotated vertical, place gauge
bar across front and rear rollers. The first screw
head should fit snugly over the edge of the
bedknife. The end of the second screw should
contact the bottom of the bedknife (Fig. 13). If there
is a gap between the front roller and the gauge bar,
lower the front roller until it contacts the gauge bar.
Verify front roller (attitude) at each end of the
bedknife.
NOTE: At this time leave a small gap between the
rear roller and gauge bar.

CHECKING OR ADJUSTING ATTITUDE FOR
USED CUTTING UNITS
NOTE: As a starting point for adjusting cutting unit
attitude, the cutting unit may be set up using the
dimensions from TABLE 1. However, because of wear
on the bedknife and reel, either the First or Second
Method must be used to insure the correct setting of the
attitude.
FIRST METHOD (Angle Indicator):
1. Rotate the cutting unit backward to gain access to
the reel and bedknife.
2. Place an angle indicator, Toro part no. 99-3503, on
the bedknife and record the bedknife angle
(Fig. 15).
Figure 15
1. Bedknife angle
3. Using a two-screw gauge bar, Toro part no. 98-
1852, set the first screw to desired height of cut.
4. Place the gauge bar across the front and rear rollers.
The first screw head needs to fit snugly over the
edge of the bedknife, while the gauge bar contacts
the front roller (Fig. 16).
NOTE: The rear roller does not have to contact the
gauge bar.
5. Place an angle indicator on the gauge bar and
record the gauge bar angle (Fig. 16).

7. Adjust the front roller to your desired cutting unit
attitude.
NOTE: Moving the front roller down will decrease
your cutting unit attitude, while moving the front
roller up will increase cutting unit attitude.
8. Set the second screw to transfer your desired cutting
unit attitude to the remaining cutting units on the
machine.
SECOND METHOD (Screw Height
Difference):
1. Rotate the cutting unit backwards to gain access to
reel and bedknife.
2. Using a two-screw gauge bar, Toro part no. 98-
1852, set the first screw to the desired height of cut.
3. Place the gauge bar across the front and rear rollers.
The first screw head needs to fit snugly over the
edge of the bedknife, while the gauge bar contacts
the front roller (Fig. 17).
NOTE: The rear roller does not have to contact the
gauge bar.
Figure 17
1. 1st screw
4. Switch first screw on the gauge bar so both screw
heads are pointed in the same direction (Fig. 18).
5. Place the gauge bar on the bedknife so both screws
contact the bedknife while the gauge bar contacts
the front and rear rollers (Fig. 18).
NOTE: Both screws must contact the flat surface of
the bedknife.

9. Put the first screw back to the normal position
(screw head hooks over bedknife) and set to desired
height cut (Fig. 17)
10. Place the gauge bar across front and rear rollers.
While the first screw head fits snugly over edge of
the bedknife and the second screw contacts the
bedknife, adjust the front roller until contacts the
gauge bar (Fig. 17).
11. Use your gauge bar to set the cutting unit attitude to
of the remaining cutting units on the machine.
C. LEVELING THE FRONT ROLLER
IMPORTANT: Toro strongly recommends the use of
a leveling plate when setting up or adjusting any reel-
type cutting unit. The leveling plate will help to
ensure accurate and consistent adjustments. Contact
your local Toro Distributor to order a leveling plate.
1. Position the cutting unit on a flat surface.
2. Position a 1/2” (13 mm) or thicker bar under the
reel blades and against the cutting edge of the
bedknife. Make sure the bar covers the full length
of the reel blades. The rear roller should not contact
the surface (Fig. 20).

3. Rock the cutting unit forward (on the reel blades
and steel bar) until the front roller contacts the flat
surface. The reel blades and bedknife must maintain
contact with the bar (Fig. 20).
4. Adjust the front brackets until both ends of the
roller are in contact with the level surface. Use a
piece of newspaper or visually check whether any
gap exists between the roller ends and the flat
surface (Fig. 21).
5. Tighten the top and bottom nuts of the front roller
brackets to 55–65 ft-lbs. (75-88 Nm).
6. Recheck roller contact with newspaper to ensure
roller has not changed position and is parallel with
the reel and bedknife.
Figure 21
D. FINALIZING HEIGHT OF CUT
IMPORTANT. Adjusting (Parallel) the bedknife to
the reel, setting the cutting unit attitude, and leveling
the front roller must be completed before finalizing
height of cut.
1. Using a two-screw gauge bar, Toro part no. 98-
1852, set the first screw to the desired height of cut.
This setting is from the bar face to the underside of
the screw head (Fig. 22).

3. If there is a gap between the rear roller and the
gauge bar, or if the rear roller will not let you put
the gauge bar on the bedknife, proceed as follows:
4. Loosen the lock nuts on the rear side brackets
(Fig. 24).
Figure 24
1. Locknut (both sides)
5. To reduce thread play, turn the rear adjusting screw
clockwise until a slight gap exists between the rear
roller and gauge bar. Then turn the rear adjusting
screw counterclockwise until the rear roller contacts
the gauge bar. After adjustment, verify that the
gauge bar contacts the rear roller on both ends of
the bedknife.
NOTE: Make sure the gauge bar is in contact with
the front roller at all times to keep correct cutting
unit attitude.
6. Slide the gauge bar toward the end of the cutting
unit to remove it. The gauge bar can now be useed
to set the remaining cutting units on the machine.

NOTE: When backlapping, the front units all operate
together, and the rear units operate together.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brake, and move the Enable/Disable switch to the
disable position.
2. Unlock and raise the seat to expose controls.
3. Open the control cover and turn the height-of-cut
selection knob to position “P” (Fig. 25).
Figure 25
1. Height-of-cut Selector Knob
NOTE: Backlapping speed may be increased by
moving the height-of-cut selection knob toward “A’.
Each position will increase speed approximately 60
rpm. After changing selector, wait 30 seconds for
the system to respond to the new speed target.
4. Make initial reel-to-bedknife adjustments
appropriate for backlapping on all cutting units that
are to be backlapped.
5. Start the engine and run it at idle speed.
DANGER: To avoid personal injury, never your
place hands or feet in the reel area while the engine
is running. Changing engine speed while
backlapping may cause reels to stall. Never change
engine speed while backlapping. Only backlap at
idle engine speed. Never attempt to turn reels by
hand or foot while the engine is running.
6. Select either the front or rear on the backlap switch
to backlap either the front or rear reels.
DANGER: To avoid personal injury, be certain that
you are clear of the cutting units before proceeding.
7. Move the Enable/Disable switch to the Enable
position. Move the Lower Mow / Lift control
forward to start backlapping operation on
designated reels.
8. Apply lapping compound with a long-handle brush
(Toro Part No. 29-9100). Never use a short handled
brush (Fig. 26).
Figure 26
1. Long handle brush
9. If reels stall or become erratic while backlapping,
the reel control light will begin to blink and the
reels will turn off. If this occurs, turn the height-of-
cut selection knob one position closer to “A’. Then,
toggle the Enable/Disable switch to the disable

LUBRICATION
Each cutting unit has (7) grease fittings (Fig. 26) that
must be lubricated regularly with No. 2 General Purpose
Lithium Base Grease.
The lubrication points are front roller (2), rear roller (2),
reel bearing (2) and bedknife adjuster.
IMPORTANT. Lubricating cutting units immediately
after washing helps purge water out of bearings and
increases bearing life.
1. Wipe each grease fitting with a clean cloth.
2. Apply grease until pressure is felt against the
handle.
NOTE: Apply grease to reel-bearing cavities until a
small amount is evident at the inboard reel seal.
3. Wipe away excess grease.

REEL BEARING ADJUSTMENT
To insure long life of the reel bearings, periodically
check if reel end play exits. The reel bearings can be
checked and adjusted as follows:
1. Loosen reel-to-bedknife contact by turning the
bedknife adjusting knob (Fig. 28) counter
-clockwise until no contact exists.

1. Bedknife adjusting knob
2. Hold on to the reel shaft and try to move the reel
assembly side to side (Fig. 29).
Figure 29
3. If end play exists, proceeded as follows:
A. Loosen the set screw securing the bearing
adjusting nut to the bearing housing located on
the left side of the cutting unit (Fig. 30).
B. Using a spanner wrench, slowly tighten the
reel bearing adjustment nut until no end play of
the reel exists. If the adjusting nut does not
eliminate reel end play, replace the reel
bearings.
NOTE: Reel bearings do not require pre-load.
Over tightening the reel bearing adjuster nut
will damage the reel bearings.
C. Retighten the set screw securing the bearing
adjusting nut to the bearing housing.
