Adjusting the Bedknife to Reel Contact

Adjusting the Bedknife Daily

Prior to mowing each day, or as required, check each cutting unit to verify proper bedknife-to-reel contact. Perform this check even though quality of cut is acceptable.

Lower the cutting units onto a hard surface.
Shut off the machine as follows:
- Gas units: Shut off the engine and disconnect the spark-plug wire.
- Electric units: Turn off the machine and disconnect the battery connector (T-handle).
Slowly rotate the reel in a reverse direction, listening for reel-to-bedknife contact.
- If no contact is evident, turn the bedbar adjusting screws clockwise (Figure 9), 1 click at a time, until you feel and hear light contact.
  Figure 9
  1. Bedbar adjusting screw
  Note: The reel must cut one sheet of paper, when inserted at a right angle to the bedknife, at both ends and the center of the reel.
  
  Note: The bedbar adjusting screws have detents corresponding to 0.018 mm (0.0007 inch) bedknife movement for each indexed position.
- If excessive contact/reel drag is evident, you need to backlap, reface the front of the bedknife, or regrind the cutting unit to achieve the sharp edges needed for precision cutting (Refer to the Toro Manual for Sharpening Reel and Rotary Mowers, Form No. 09168SL).
Important: Light contact is preferred at all times. If you do not maintain light contact, the bedknife/reel edges will not sufficiently self-sharpen, and dull cutting edges will result after a period of operation. If you maintain excessive contact, bedknife/reel wear will be accelerated, uneven wear can result, and the quality of cut may decline.

Note: For eFlex cutting units, the reel-to-bedknife contact has a significant impact on energy consumption. Very light contact is best for cutting performance and battery consumption.

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. Occasionally run a file across the front edge to remove this burr to improve cutting.After extended running, a ridge eventually develops at both ends of the bedknife. Round off these notches or file them flush with the cutting edge of the bedknife to ensure smooth operation.

Adjusting the Bedknife after Grinding, Backlapping, or Disassembly

Use this procedure after grinding, backlapping, or disassembling the reel. This is not a daily adjustment.

Note: For eFlex cutting units, the reel-to-bedknife contact has a significant impact on energy consumption. Very light contact is best for cutting performance and battery consumption.

Position the cutting unit on a flat, level work surface.
Tip the cutting unit to expose the bedknife and reel.

Note: Ensure that the nuts on the back of the bedbar adjusting screws are not resting on the work surface (Figure 8).
Rotate the reel so that 1 of the blades crosses the bedknife edge between the first and second bedknife screw heads located on the right side of the cutting unit.
Make and identifying mark on the blade where it crosses the bedknife edge.

Note: Doing this will make later adjustments easier.
Insert a 0.05 mm (0.002 inch) shim between the blade and the bedknife edge at the point marked in step 4.
Turn the right bedbar adjusting screw (Figure 9) until you feel light pressure on the shim when sliding it side-to-side. Remove the shim.
For the left side of the cutting unit, slowly rotate the reel so that the closest blade crosses the bedknife edge between the first and second screw heads.
Repeat steps 4 through 6 for the left side of the cutting unit and left bedbar adjusting screw.
Repeat steps 5 and 6 until there is light pressure at the contact points on both the left and right sides of the cutting unit.
To obtain light contact between the reel and bedknife, turn each bedbar adjusting screw clockwise 3 click.

Note: Each click on the bedbar adjusting screw moves the bedknife 0.018 mm (0.0007 inches). Do not overtighten the adjusting screws.Turning the adjusting screw clockwise moves the bedknife edge closer to the reel. Turning the adjusting screw counterclockwise moves the bedknife edge away from the reel.
Test the cutting performance by inserting a long strip of cutting performance paper between the reel and bedknife, perpendicular to the reel and bedknife (Figure 10). Slowly rotate the reel forward to cut the paper.

Figure 10

Note: If excessive contact/reel drag is evident, you may need to backlap or grind the reel and bedknife to achieve the sharp edges needed for precision cutting.

Grinding the Bedknife

Relief-Grinding the Reel

The new reel has a land width of 0.76 to 1.27 mm (0.030 to 0.050 inch) and a 30 degree relief grind.

When the land width gets larger than 3 mm (0.120 inch) wide, do the following:

Apply a 30 degree relief grind on all reel blades until the land width is 0.76 to 1.27 mm (0.030 to 0.050 inch) wide (Figure 11.
Figure 11
1. 30 degrees
2. 1.3 mm (0.050 inch)
Spin grind the reel to achieve <0.025 mm (0.001 inch) reel run-out.

Note: This causes the land width to grow slightly.

Note: To extend the longevity of the sharpness of the edge of the reel and the bedknife—after grinding the reel and/or the bedknife—check the reel to bedknife contact again after cutting 6 greens, as any burrs will be removed, which may create improper reel to bedknife clearance and thus accelerate wear.

Checking the Top Grind Angle

The angle that you use to grind your bedknives is very important.

Use the angle indicator and the angle-indicator mount to check the angle that your grinder produces and then correct for any grinder inaccuracy.

Place the angle indicator on the bottom side of the bedknife as shown in Figure 12.
Figure 12
1. Bedknife (vertical)
2. Angle indicator
Press the Alt Zero button on the angle indicator.
Place the angle-indicator mount on the edge of the bedknife so that the edge of the magnet mates with the edge of the bedknife (Figure 13).

Note: The digital display should be visible from the same side during this step as it was in step 1.

Position the spacer below the sideplate-mounting flange when the height-of-cut settings range from 3 mm to 25 mm (1/8 inch to 1 inch) as shown inFigure 15.
Figure 15
1. Sideplate-mounting flange
2. Spacer
3. Roller bracket

Raise the rear of the cutting unit and place a block under the bedknife.
Remove the 2 nuts securing each roller bracket and spacer to each sideplate mounting flange.
Lower the roller and screws from the sideplate mounting flanges and spacers.
Place the spacers onto the screws above of below the roller brackets, as required (Figure 14 or Figure 15).
Secure the roller bracket and spacers to the underside of the mounting flanges with the nuts previously removed.
Verify that the bedknife-to-reel contact is correct. Tip the mower to expose the front and rear rollers and the bedknife.

Note: The position of the rear roller to the reel is controlled by the machining tolerances of the assembled components and paralleling is not required. A limited amount of adjustment is possible by setting the cutting unit on a surface plate and loosening the sideplate mounting bolts (Figure 16). Adjust and tighten the bolts when finished.
Figure 16
1. Sideplate-mounting bolts
Important: Whenever you must tip the cutting unit to expose the bedknife/reel, prop up the rear of the cutting unit to ensure that the nuts on the back end of the bedbar adjusting screws are not resting on the work surface (Figure 8).

Adjusting the Height of Cut

This cutting unit comes standard with the Edgemax Micro-cut bedknife and standard bedbar. The effective height of cut depends on previous mower configurations and turf conditions (i.e., roller type, bedknife behind center distance, soft or firm greens, season conditions). Set the initial height of cut 0.25 mm to 0.38 mm (0.010 to 0.015 inch) higher than the previous greensmower setup and adjust it to match conditions.

Note: For heights of cut greater than 13 mm (0.500 inch), install the high-height-of-cut kit.

Use the following chart to determine which bedknife is best suited for the desired height of cut.

Recommended Bedknife/Height of Cut Chart
Bedknife	Part Number	Height of Cut

Adjusting the Cut-Off Bar

Adjust the cut-off bar to ensure that the clippings are cleanly discharged from the reel area, as follows:

Note: The bar is adjustable to compensate for changes in turf conditions. Adjust the bar closer to the reel when the turf is extremely dry. By contrast, adjust the bar further away from the reel when the turf conditions are wet. The bar should be parallel to the reel to ensure optimum performance. Adjust it after sharpening the reel on a reel grinder.

Loosen the screws securing the top bar (Figure 23) to the cutting unit.
Figure 23
1. Cut-off bar
Insert a 1.5 mm (0.060 inch) feeler gauge between the top of the reel and the bar and tighten the screws.

Important: Ensure that the bar and reel are equal distance apart across the complete reel.

Servicing the Bedbar/Bedknife

Only a properly trained mechanic should service the bedbar and bedknife to prevent damage to the reel, bedbar, or bedknife. Take the cutting unit to your authorized Toro distributor for service. Refer to the Service Manual for your traction unit for complete instructions, special tools, and diagrams for servicing the bedknife. Should you need to remove or assemble the bedbar yourself, the instructions and specifications for servicing the bedknife are provided below.

Important: Always follow the bedknife procedures detailed in your Service Manual when servicing the bedknife. Failure to install and grind the bed knife correctly can damage to the reel, bedbar, or bedknife.

Backlapping the Reel

Danger

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

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

Stay away from the reel while backlapping.
Never use a short-handled paint brush for backlapping. For handle assembly parts, contact your authorized Toro distributor.

You can backlap the reels either by leaving the cutting unit on the traction unit or removing the cutting unit completely from the traction unit. If you leave the cutting unit on the traction unit, move the hex coupler between the main drive and cutting unit drive to the decoupled position to prevent excessive wear to the reel brake.

Position the machine on a clean, level surface.
Shut off the machine as follows:
- Gasoline units: Shut off the engine and disconnect the spark-plug wire.
- Electric units: Turn off the machine and disconnect the battery connector (T-handle).
Engage the parking brake.
Connect the backlapping machine to the cutting unit by connecting a 1/2-inch hex socket to the reel pulley output shaft on the left side of the cutting unit.

Note: Additional instructions and procedures on backlapping are available in the Toro Sharpening Reel and Rotary Mowers Manual (Form No. 80-300PT).

Note: For a better cutting edge, run a file across the front face of the bedknife when you complete the lapping operation. This removes any burrs or rough edges that may have built up on the cutting edge. A very light file touch may be necessary on the top edge to break the burr off completely from the cutting edge.

Note: If you leave the cutting unit attached to the machine during backlapping, couple the hex shaft of the machine back to the cutting unit.
