. After the adjustment is accomplished, check to see if the reel can pinch paper when inserted from the front and cut the paper when inserted at a right angle to the bedknife (Figure 5). 1 Note: It should be possible to cut the paper with minimum contact between the bedknife and the reel blades. Should excessive reel drag be evident, it will be either necessary to backlap or regrind the cutting unit to achieve the sharp edges needed for precision cutting (refer to the Toro Reel Sharpening Manual).
Important: Whenever the cutting unit has to be tipped to expose bedknife/reel, prop up rear of cutting unit to make sure nuts on back end of bedbar adjusting screws are not resting on work surface (Figure 3). 5 Figure 7 1. Sideplate mounting flange Adjusting the Height of Cut 3. Roller bracket 2. Spacer No Parts Required To adjust rear roller proceed as follows: Procedure 1. Raise the rear of the cutting unit and place a block under the bedknife.
4. Rotate the adjusting screw until the roller contacts the front of the gauge bar. Adjust both ends of the roller until the entire roller is parallel to the bedknife. Important: When set properly, the rear and front rollers will contact the gauge bar and the screw will be snug against the bedknife. This ensures that the height-of-cut is identical at both ends of the bedknife. 5. Tighten the nuts to secure the adjustment. Do not overtighten them. Tighten them only enough to remove play from the washer.
7 Installing the Target Plate No Parts Required Procedure If you will be using the cutting unit on an eFlex traction unit, install the provided target plate as described in the eFlex Traction Unit Operator’s Manual. If you will be using the cutting unit on gas powered machines, you do not need the target plate. If you will be using the cutting unit on both gas units and the eFlex machines, you can install the target plate and leave it installed regardless of which machine you use it on.
Product Overview Specifications Tractors These cutting units will mount on the appropriate size Flex and eFlex Traction Units. Height of Cut Cutting height is adjusted on the front roller by two vertical screws and held by two locking cap screws Height Of Cut Range Standard bench height of cut range is .062 inch (1.6 mm) to .500 inch (12.7 mm). Bench height of cut range with the High Height of Cut Kit installed is .285 inch (7 mm) to 1.00 inch (25 mm).
Operation 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.
. Install the belt. 12. Ensure that the compression spring is applying tension to the belt (Figure 14). 13. Tighten the bearing housing nut. 14. Install the belt cover. Figure 14 1.

Remove the belt (Figure 14). 6.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Servicing the Bedbar Removing the Bedbar 1. Turn the bedbar adjusting screw, counterclockwise, to back the bedknife away from the reel (Figure 16). 3 g016970 4 1 Figure 18 1. Bedbar bolt 2. Nut 2 3. Steel washer 4. Nylon washer Assembling the Bedbar 1. Install the bedbar, positioning the mounting ears between the washer and bedbar adjuster. g014641 2.
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. A very light file touch may be necessary on the top edge to break the burr off completely from the cutting edge. 2 Note: If the cutting unit was left attached to the machine during backlapping remember to couple the hex shaft of the machine back to the cutting unit. 1 g014642 Figure 19 1.
