Adjustments
Note: Determine the left and right sides of
themachine from the normal operating position.
After the cutting unit is unboxed, use the following
procedures to assure the cutting unit is adjusted
properly.
1. Check each end of the reel for grease. Grease
should be visibly evident in the reel bearings.
2. Insure that all nuts and bolts are securely fastened.
3. Position the lift roller to match suspension.
•Upper position for standard support height
•Lower position increased support height
4. Check to make sure the bedknife and reel are
parallel. Refer to Adjusting The Bedknife To The
Reel, next.
Adjusting the Bedknife to the
Reel
1. Remove the cutting units from the traction unit
and position them on a level work surface.
2. Move the bedknife closer to the reel blades by
loosening the bottom adjusting screw on each side
of the cutting unit, then tightening the top
adjusting screw on each side of the cutting unit.
:Use only a M13 wrench, 8 to 15 cm
length when adjusting the bedknife screws. A
longer wrench will provide too much leverage and
may distort the mounting plate for the adjustment
screws.
3. After adjusting the bedknife to the reel, make sure
that both the top and bottom adjusting screws are
secured on both ends of the cutting unit.
4. After the adjustment, check to see if the reel can
pinch paper when inserted from the front and cut
paper when inserted at a right angle. It should be
possible to cut paper with minimum contact
between the bedknife and the reel blades.

Choosing Cutting Unit Attitude
There are four positions for the front roller brackets.
Position 1:
Least aggressive; use for very soft and tender turf.
Height-of-cut range: 2.4mm–21.3mm

Position 2:
Standard position; use for most conditions.
Height-of-cut range: 2.4mm–18.3mm
Position 2
Note: The top frame hole and top bracket hole
will yield position 2 (standard position).
Position 3:
More aggressive; use on firm turf or higher height of
cuts.
Height-of-cut range: 2.4mm–15.7mm
Position 3
Position 4:
Most aggressive; use only on very firm greens or at
the higher heights of cut.
Height-of-cut range: 2.4mm–12.7mm
Position 4
Note: Amore aggressive setting will increase
grass removal and provide a cleaner cut, but may
cause increased scalping and marking.
Note: Amore aggressive setting will be required
to compensate for reel wear.
Leveling the Front Roller to the
Reel
1. Position the cutting unit on a flat, level surface.
2. Position a 6 mm or thicker plate under the reel
blades and against the front face of the bedknife.
Note:Be sure the plate covers the full length of
the reel blades and three blades contact the plate.
3. Loosen the locknuts retaining the right-front roller
bracket.
Figure 4
1. Right front roller bracket
2. Upper right roller mounting bolt
4. While holding the reel securely on the plate and
maintaining pressure on the front roller, rotate the
upper right roller mounting bolt (Fig. 4). This
mounting bolt has an offset, which when rotated,
acts as an eccentric (cam) to raise or lower the
roller. On the bolt head there is an internal
diameter dot that denotes the offset of the bolt.
The dot indicates the direction in which the right
end of the roller moves when the bolt is turned.
Note: If additional adjustment is required, replace
one screw on the left-hand bracket with another
bolt, part no. 93-2573. Make sure that both front
roller brackets are in the same hole.
5. To verify whether the roller is level, try inserting a
piece of paper under each end of the roller.
6. When the roller is level, tighten the nuts securely.

Adjusting the Top Shield Height
1. Loosen the bolts and nuts securing the shield to
each side plate.
2. Adjust the shield to the desired position and
secure the fasteners
3. Repeat the procedure on the remaining cutting
units and adjust the top bar.
Note: The shield can be raised for extreme wet
conditions.
Adjusting the Top Bar
Adjust the top bar, under the rear shield, to assure
clippings are cleanly discharged from the reel area.
1. Loosen the screws securing the top bar. Insert a
1.5mm feeler gauge between the top of the reel
and the bar and tighten the screws. Assure the bar
and reel are equal distance apart across the
complete reel.
2. Repeat adjusting the settings on the remaining
cutting units.
Note: The bar is adjustable to compensate for
changes in turf conditions. It should be adjusted
closer to the reel when the turf is extremely wet.
By contrast, adjust the bar further away from the
reel when turf conditions are dry. The bar should
be adjusted whenever you change the top shield
height, the reel wears, or the reel is sharpened by
grinding.
Adjusting the Height of Cut
1. Verify that the front roller is level and the
bedknife-to-reel contact is correct.
2. Turn the cutting unit over (90°) and rest it on the
rear roller and top rear tabs. Loosen the locknuts
on the capscrews that retain the rear roller
brackets (Fig 5).
3. On a gauge bar (Part no. 13-8199), set the head of
the screw to the desired height of cut (Fig 5). This
measurement is from the bar face to the underside
of the screw head.
Figure 5
1. Guage bar
2. Roller bracket bolt
3. Height-of-cut knob
4. Lower the cutting units onto a hard surface, shut
off the engine, and remove the ignition key.
5. Place the bar across the front and rear rollers and
adjust the height-of-cut knob until the underside
of the screw head engages the bedknife cutting
edge.
: Repeat the procedure on each end of the
bedknife and tighten locknuts that retain rear roller
brackets on each end.
Note: The cutting units will deliver differing effective
heights of cut, depending on their configuration.
Effective cutting height may be influenced by the
following factors: turf conditions, roller profiles,
cutting unit attitude, cutting unit accessories, weight
of the cutting units and bedknife profile. Therefore,
bench setting a cutting unit does not equal the
effective (actual) height of cut you achieve. You must
determine how to adjust your cutter on the bench to
achieve a comparable height of cut to a cutting unit of
a different configuration, model, or brand

Operation
Note: Determine the left and right sides of
themachine from the normal operating position.
Cutting Unit Daily Adjustiments
Prior to each day's mowing, or as required, each
cutting unit must be checked to verify proper
bedknife-to-reel contact. This must be performed
even though quality of cut is acceptable.
:Light contact is preferred at all times. If
light contact is not maintained, bedknife/reel edges
will not sufficiently self-sharpen and dull cutting
edges will result after a period of operation. If
excessive contact is maintained, bedknife/reel wear
will accelerate, uneven wear can result, and quality of
cut may be adversely affected.
Note: As the reel blades continue to run against the
bedknife, a slight burr will appear on the front cutting
edge surface the full length of the bedknife. Running a
file across the front edge to remove this burr will
improve cutting.
After extended running, a ridge will eventually
develop at both ends of the bedknife. These notches
must be rounded off or filed flush with the cutting
edge of the bedknife to assure smooth operation.
Maintenance
Note: Determine the left and right sides of
themachine from the normal operating position.
Greasing Bearings and
Bushings
Each cutting unit has (6) grease fittings that must be
lubricated regularly with No. 2 General Purpose
Lithium Base Grease.
The grease fitting locations and quantities are:
•Reel bearings (2) (Fig. 6)
•Front and rear rollers (2 ea.) (Fig. 6).
: Lubricating the cutting units
immediately after washing helps purge water from the
bearings and increases bearing life.
1. Wipe each grease fitting with a clean cloth
2. Apply grease until pressure is felt against the
handle.
: Do not apply too much pressure
or grease seals will be permanently damaged.
3. Wipe away excess grease.
Figure 6
Backlapping the Cutting Units
1. Position the machine on a clean, level surface,
lower the cutting units, stop the engine, engage
the parking brake and remove the key from the
ignition switch.
2. Remove the reel motors from the cutting units and
disconnect and remove the cutting units from the
lift arms.
3. Connect the backlapping machine to the cutting
unit by inserting a piece of 9mm square stock into
the splined coupling at the right end of the cutting
unit.
Note: Additional instructions and procedures on
backlapping are available in the TORO Sharpening
Reel & Rotary Mowers Manual Form No. 80-300PT.
Note:For a better cutting edge, run a file across the
front face of the bedknife after completing the lapping
operation. This will remove any burrs or rough edges
that may have built up on the cutting edge.
