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 7). Test the quality of cut by cutting a test swath before using the cutting unit to ensure that the finished cut is correct.
1. Slowly rotate the reel in a reverse direction, listening for reel-to-bedknife contact. Note: The adjustment knobs have detents corresponding to 0.018 mm (0.0007 inch) bedknife movement for each indexed position. Refer to Adjusting the Bedknife to the Reel (page 7). 2. Test the cutting performance by inserting a long strip of cutting performance paper (Toro Part 125-5610) between the reel and the bedknife, perpendicular to the bedknife (Figure 7).
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. 8. Turn the left bedbar adjuster clockwise until the shim can be slid through the reel to bedknife gap with light drag. 9.
3. Remove the 2 nuts securing each roller bracket and spacer to each side-plate mounting flange. 4. Lower the roller and screws from the side-plate mounting flanges and spacers. 5. Place the spacers onto the screws on the roller brackets. 6. Secure the roller bracket and spacers to underside of side plate mounting flanges with the nuts previously removed. 7. Verify that the bedknife-to-reel contact is correct. Tip the mower to expose the front and rear rollers and bedknife.
Adjusting the Height of Cut (HOC) ends of roller until the entire roller is parallel to the bedknife. Note: For heights of cut greater than 2.54 cm (1 inch) install the High Height-of-Cut Kit. 1. Loosen the locknuts securing the height-of-cut brackets to the cutting-unit side plates (Figure 14). g027266 Figure 16 Important: When set properly, the rear and front rollers will contact the gauge bar and the screw will be snug against the bedknife.

Use the following chart to determine which bedknife is best suited for the desired height of cut. Bedknife/Height of Cut Chart Bedknife Part No. Bedknife Lip Height Height of Cut Low HOC 121-3167 (18 inch) 5.6 mm 6.4 to 12.7 mm (Model 03489) 110-4084 (22 inch) (0.220 inch) (0.250 to 0.500 inch) 5.6 mm 6.4 to 12.7 mm (0.220 inch) (0.250 to 0.
Height-of-Cut Chart Terms Height-of-Cut Setting (HOC) This corresponds to 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 roller and the rear roller. g033036 Figure 18 1. Rear spacers 3. Aggressiveness of cut 2. Side-plate mounting flange Effective Height of Cut This is the actual height that the grass has been cut.
Maintenance Lubricating the Cutting Units Using the Kickstand when Tipping the Cutting Unit Regularly lubricate the 5 grease fittings of each cutting unit (Figure 21) 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.
Relief-Grinding the Reel 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 2 fairways, as any burrs will be removed, which may create improper reel to bedknife clearance and thus accelerate wear. The new reel has a land width of 1.3 to 1.5 mm (0.050 to 0.060 inch) and a 30° relief grind. When the land width gets larger than 3 mm (0.120 inch) wide, do the following: 1.
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.

Servicing the Bedbar Removing the Bedbar 1. Turn the bedbar-adjusting screws counterclockwise to back the bedknife away from the reel (Figure 28). g034113 Figure 26 2. Angle indicator 1. Bedknife (vertical) 2. Press the Alt Zero button on the angle indicator. 3. Place the angle-indicator mount on the edge of the bedknife so that the edge of the magnet is mated with the edge of the bedknife (Figure 27).

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 g279161 Figure 32 of the side-plate boss. Place a steel washer outside each of the nylon washers (Figure 30). 3. 1. Bedbar 2.
Servicing the HD Dual Point Adjusters (DPA) 1. 2. 3. Remove all parts (refer to the Installation Instructions for the HD DPA Kit and to Figure 34). Apply anti-seize compound to the inside of the bushing area on cutting unit center frame (Figure 34). Align the keys on flange bushings to the slots in the frame and install the bushings (Figure 34). 4. Install a wave washer onto the adjuster shaft and slide the adjuster shaft into the flange bushings in the frame of the cutting unit (Figure 34). 5.
16. Repeat this procedure on the other end of the cutting unit. Servicing the Roller 17. Adjust the bedknife to the reel; refer to Adjusting the Bedknife to the Reel (page 7). The Roller Rebuild Kit (Part No. 114-5430) and the Roller Rebuild Tool Kit (Part No. 115-0803) (Figure 35) are available for servicing the roller. The Roller Rebuild Kit includes all the bearings, bearing nuts, inner seals, and outer seals to rebuild a roller.
