This increases the area for the rear grass baskets.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Making Adjustments Adjusting the Bedknife to the Reel Use this procedure to set the bedknife to the reel and to check the condition of the reel and bedknife and their interaction. After completing this procedure, always test the cutting unit performance under your field conditions. You may need to make further adjustments to obtain optimal cutting performance. Figure 9 1. Kickstand 4.
6. Secure the roller bracket and spacers to the underside of the side-plate mounting flanges with the nuts previously removed. 11. From this position (1 click in and shim not passing through) turn the bedbar adjusters clockwise 2 clicks each. Note: Each click turned moves the bedknife 0.018 mm (0.0007 inch). Do not overtighten the adjusting screws. 7. Verify that the bedknife-to-reel contact is correct. Tip the mower to expose the front and rear rollers and the bedknife. 12.
Rear Spacers Height-of-Cut Chart Terms The number of rear spacers determines the aggressiveness of cut for the cutting unit. For a given height of cut, adding spacers below the side-plate mounting flange increases the aggressiveness of the cutting unit. All cutting units on a given machine must be set to the same aggressiveness of cut (number of rear spacers, Part No. 106-3925); otherwise, the after-cut appearance could be negatively affected (Figure 13).

Adjusting the Height of Cut Note: For heights of cut greater than 2.5 cm (1 inch) install the High Height-of-Cut Kit. 1. Loosen locknuts securing height-of-cut brackets to cutting-unit side plates (Figure 15). Figure 17 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. Figure 15 1. Adjusting screw 3. Height-of-cut bracket 6.

Checking and Adjusting the Cutting Unit The dual-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 dual-knob/bedbar design gives the necessary control to provide a continual self-sharpening action—thus maintaining sharp cutting edges, ensuring a good quality of cut, and greatly reducing the need for routine back lapping.
Servicing the Bedknife The bedknife service limits are listed in the following charts. Important: Operating the cutting unit with the bedknife below the service limit may result in poor after-cut appearance and reduce the structural integrity of the bedknife for impacts.

Maintenance Servicing the Bedbar Lubricating the Machine Removing the Bedbar 1. Turn the bedbar adjusting screws counterclockwise to back the bedknife away from the reel (Figure 24). Regularly lubricate the 5 grease fittings of each cutting unit (Figure 23) with No. 2 lithium grease. There are 2 lubrication points on the front roller, 2 on the rear roller, and 1 at the reel-motor spline.
Assembling the Bedbar 1. Install the bedbar, positioning the mounting ears between the washer and the bedbar adjuster. 2. Secure the bedbar to each side plate with the bedbar bolts (nuts on bolts) and the 6 washers. Note: Position a nylon washer on each side of the side-plate boss. Place a steel washer outside each of the nylon washers (Figure 26). 3. Torque bedbar bolts to 37 to 45 N-m (27 to 33 ft-lb).
