Adjustments

4. Loosen locknuts retaining the left-hand bedbar pivot

housing (Fig. 2).

Note: Determine the left and right sides of the machine from the normal operating position.

After the cutting unit is unboxed, use the following procedures to ensure that the cutting units are adjusted properly.

1. Check each end of the reel for grease. Grease should be

visibly evident in the reel bearings.

2. Ensure that all nuts and bolts are securely fastened.

3. Position the lift roller to match the suspension.

• Upper position for standard transport height

• Lower position for increased transport height

4. Check to make sure that the bedknife and reel are

parallel; refer to Adjusting the Bedknife to the Reel, page 3.

Adjusting the Bedknife to the Reel

1. Remove cutting units from traction unit and position on

a level work surface.

5. Rotate flange nuts (Fig. 2, inset), on top and bottom of

frame tab, clockwise or counterclockwise to raise or lower end of bedbar, as required. Do not loosen bottom flange nut. Tighten flangenuts against frame tab when desired adjustment is attained.

6. Check adjustments by repeating steps 2 and 3.

7. When light contact on paper is evident at each end of

bedknife, tighten locknuts retaining pivot housing securely.

2. Make sure reel contact is removed by turning bedknife

adjustment knob counterclockwise (Fig. 2).

Leveling the Front Roller to the Reel

1. Position the cutting unit on a flat, level surface.

2. Place a 1/4 inch or thicker plate under the reel blades

and against the front face of the bedknife.

Note: Be sure that 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 (Fig. 4).

Note: A more aggressive setting will increase grass removal and provide a cleaner cut, but may cause increased scalping and marking.

down

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 I.D. dot which denotes the offset of the bolt. The dot indicates in which direction 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 eccentric bolt, Part No. 93-2573. Ensure that both front roller brackets are in the same hole.

5. To verify if 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 bolts and nuts securing the shield to each side

plate.

2. Adjust the shield to the desired position and secure the

fasteners.

3. Repeat this procedure on the remaining cutting units

and adjust the top bar.

Note: The shield can be raised for extremely wet conditions.

Adjusting the Top Bar

Adjust the top bar, under the rear shield, to ensure that clippings are cleanly discharged from the reel area.

1. Loosen the screws securing the top bar. Insert a 0.06 in.

(1.5 mm) feeler gauge between the top of the reel and bar and tighten the screws. Ensure that the bar and reel are an equal distance apart across the complete reel.

2. Repeat the settings on the remaining cutting units. Note: The bar is adjustable to compensate for changes in

turf conditions. The bar 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 the top shield height is changed, the reel wears, or the reel is sharpened by grinding.

profile. Therefore, benchsetting a cutting unit does not equal the effective (actual) height of cut you achieve. You need to 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.

2. Roller bracket bolt

3. Height-of-cut knob

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 bolts retaining the rear roller brackets (Fig. 5).

3. On the 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.

4. Place the bar across the front and rear rollers and adjust

the height-of-cut knob (Fig. 5) until the underside of the screw head engages the bedknife cutting edge.

Important Repeat this procedure on each end of the

bedknife and tighten the locknuts retaining the rear roller brackets on each end.

Note: The cutting units will deliver differing effective height of cuts 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 cutting units, and bedknife

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Cutting Unit Characteristics

The single knob bedknife-to-reel adjustment system incorporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing performance. The precise adjustment possible with the single knob/bedbar design gives the necessary control to provide a continual self-sharpening action—thus maintaining sharp cutting edges, ensuring good quality-of-cut, and greatly reducing the need for routine backlapping.

Page 6

Daily Adjustments of Cutting Unit

Prior to mowing each day, 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.

1. Lower the cutting units onto a hard surface, shut off the

engine, and remove the ignition key.

2. Slowly rotate the reel in a reverse direction, listening

for reel-to-bedknife contact. If no contact is evident, turn the bedknife adjusting knob clockwise, one click at a time, until light contact is felt and heard.

Note: The adjustment knob has detents corresponding to

0.0007 in. (0.018 mm) bedknife movement for each indexed position.

3. If excessive contact is felt, turn the bedknife adjusting

knob counterclockwise, one click at a time until no contact is evident. Then turn the bedknife adjusting knob one click at a time clockwise, until light contact is felt and heard.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

Greasing the Bearings and Bushings

Each cutting unit has 7 grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease.

The grease fitting locations and quantities are:

• Adjusting knob pivot point (Fig. 6)

• Reel bearings (2) (Fig. 6)

• Front and rear rollers (2 ea.) (Fig. 6)

Important Lubricating the cutting units immediately

after washing helps purge water out of the bearings and increases bearing life.

1. Wipe each grease fitting with a clean rag.

Important Light contact is preferred at all times. If

light contact is not maintained, the 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 be accelerated, 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 along the full length of the bedknife. If a file is occasionally run across the front edge to remove this burr, improved cutting can be obtained.

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 ensure smooth operation.

2. Grease the reel bearings (Fig. 6) until grease comes out

of the pressure relief.

3. Grease the front and rear roller bearings (Fig. 6) until

grease begins to show around the seal lips.

4. Grease the adjusting pivot point (Fig. 6).

Important Do not apply too much pressure or the

grease seals will be permanently damaged.

Backlapping the Cutting Units

Caution

Contact with the reels or other moving parts can result in personal injury.

Keep fingers, hands, and clothing away from the reels or other moving parts.

1. Position the machine on a clean, level surface, lower the

cutting units, stop the engine, engage the parking brake, and remove the ignition key.

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 3/8 in. 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 when the lapping operation is completed. This will remove any burrs or rough edges that may have built up on the cutting edge.
