Product Overview Operation Specifications Refer to your traction unit Operator’s Manual for detailed operation instructions. Before using the cutting unit each day, adjust the bedknife; refer to Adjusting the Bedknife to the Reel (page 8). Test the quality of cut by cutting a test swath before using the cutting unit to ensure that the finished cut is correct.
Note: The adjustment knobs have detents corresponding to 0.023 mm (0.0009 inch) bedknife movement for each indexed position. Refer to Adjusting the Bedknife to the Reel (page 8). 2. Test the cutting performance by inserting a long strip of cutting performance paper (Toro Part No. 125-5610) between the reel and the bedknife, perpendicular to the bedknife (Figure 10). Slowly rotate the reel forward; it should cut the paper. g031270 Figure 11 1. Lead-in chamfer on right end of bedknife 2. 6 mm (0.
Note: Adjusting 1 side of the cutting unit affects the other side, the 2 clicks will provide clearance for when the other side is adjusted. Note: If starting with a large gap, both sides should initially be drawn closer by alternately tightening the right and left sides. 7. Slowly rotate the reel so that the same blade that you checked on the right side is crossing the bedknife approximately 25 mm (1 inch) in from the end of the bedknife on the left side of the cutting unit.
Note: If excessive reel drag occurs, either backlap or grind the cutting unit to achieve the sharp edges needed for precision cutting. Adjusting the Rear Roller 1. Adjust the rear roller brackets (Figure 15) to the desired height-of-cut range by positioning the required amount of spacers below the side-plate mounting flange (Figure 15) per the HOC Chart. g020698 Figure 16 1. Side-plate mounting cap screws Adjusting the Height of Cut (HOC) g003324 Figure 15 1. Spacer 3. Side-plate mounting flange 2.
g011864 Figure 18 3. Nut 1. Gauge bar 2. Height-adjusting screw 3. Hook the screw head on the cutting edge of the bedknife and rest the rear end of the bar on the rear roller (Figure 19). 4. Rotate the adjusting screw until the front roller contacts the gauge bar (Figure 19). Adjust both ends of roller until the entire roller is parallel to the bedknife.

Height-of-Cut Chart Terms Height-of-Cut Setting (HOC) This is the desired height of cut. Bench-Set Height of Cut The bench-set height of cut is the height at which the top edge of the bedknife is set above a flat level surface that contacts the bottom of both the front and rear roller. g011863 Figure 22 1. Rear spacers 3. Aggressiveness of cut 2. Side-plate mounting flange Effective Height of Cut This is the actual height to which the grass has been cut.
Maintenance The lubrication points are the front roller (2), the rear roller (2), and the motor spline (1). Using the Kickstand When Tipping the Cutting Unit Note: Lubricating the cutting units immediately after washing helps purge water out of the bearings and increases bearing life.
Servicing the Bedknife The bedknife service limits are listed in the following chart. 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.

Edge of the magnet mated 4. Angle indicator with the edge of the bedknife 4. Remove each bedbar bolt, allowing the bedbar to be pulled downward and removed from machine bolt (Figure 31). Account for 2 nylon washers and 1 stamped steel washer on each end of the bedbar (Figure 32).
5. Tighten the spring-tension nut until the spring is collapsed, then back off 1/2 turn (Figure 33). A. Torque the 2 outer screws to 1 N∙m (10 in-lb); refer to Figure 34. B. Working form the center of the bedknife, torque the screws to 23 to 28 N∙m (200 to 250 in-lb); refer to Figure 34. g016648 Figure 33 1. Spring-tension nut 2. Spring Installing the Bedknife 1. g279162 Figure 35 Remove the rust, scale, and corrosion from the bedbar surface and apply a thin layer of oil to the bedbar surface.
Servicing the HD Dual Point Adjusters (DPA) 1. 2. Remove all parts (refer to the Installation Instructions for the HD DPA Kit (Model No. 120-7230) and to Figure 36). 3. Align the keys on flange bushings to the slots in the frame and install the bushings (Figure 36). 4. Install a wave washer onto the adjuster shaft and slide the adjuster shaft into the flange bushings in the cutting unit frame (Figure 36). 5. Secure the adjuster shaft with a flat washer and lock nut (Figure 36).
Servicing the Roller inner seals, and outer seals to rebuild a roller. The Roller Rebuild Tool Kit includes all the tools and the installation instructions required to rebuild a roller with the roller rebuild kit. Refer to your parts catalog or contact your authorized Toro distributor for assistance. The Roller Rebuild Kit (Part No. 114-5430) and the Roller Rebuild Tool Kit (Part No. 115-0803) (Figure 37) are available for servicing the roller.
