Note: All accessories and kits are 1 per cutting unit unless otherwise specified.
Operation 4. Turn the right bedbar adjuster clockwise until you feel light pressure (i.e. drag) on the shim, then back off the bedbar adjuster two clicks and remove the shim. (Since adjusting one side of the cutting unit affects the other side, the two clicks will provide clearance for when the other side is adjusted) Note: Determine the left and right sides of the machine from the normal operating position.
Adjusting the Rear Roller 1. Adjust the rear roller brackets (Figure 13) to the desired height of cut range by positioning the required amount of spacers below the side plate mounting flange (Figure 13) per the HOC Chart. g020698 Figure 14 1. Side plate mounting cap screws Figure 13 1. Spacer 3. Side plate mounting flange 2. Roller bracket Height-of-Cut Chart Terms 2. Raise rear of cutting unit and place a block under bedknife.

Adjusting the Height of Cut 1. Loosen locknuts securing height-of-cut brackets to cutting unit side plates (Figure 16). Figure 18 Figure 16 1. Adjusting screw 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. 3. Height-of-cut bracket 2. Locknut 2. Loosen nut on gauge bar (Figure 17) and set adjusting screw to desired height-of-cut.
Cutting Unit Characteristics 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 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 2. Using a rag or thickly padded glove, hold on to the reel blade and try to move the reel assembly side to side (Figure 26). Lubrication Each cutting unit has (6) grease fittings (Figure 24) that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. The lubrication points are front roller (2), rear roller (2) and reel bearing (2). Note: Lubricating cutting units immediately after washing helps purge water out of bearings and increases bearing life. 1.
Servicing the Bedbar Removing the Bedbar 1. Turn bedbar adjuster screws, counterclockwise, to back bedknife away from reel (Figure 28). Figure 30 1. Bedbar bolt 2. Nut Assembling the Bedbar 1. Install bedbar, positioning mounting ears between washer and bedbar adjuster. 2. Secure bedbar to each side plate with bedbar bolts (nuts on bolts) and 6 washers. A nylon washer is to be positioned on each side of side plate boss. Place a steel washer outside each of the nylon washers (Figure 30).
Servicing the HD Dual Point Adjusters (DPA) 4. Install a wave washer onto the adjuster shaft and slide the adjuster shaft into the flange bushings in the cutting unit frame (Figure 32). 1. Remove all parts (refer to Installation Instructions for HD DPA Kit Model No. 120–7230 and to Figure 32). 5. Secure the adjuster shaft with a flat washer and lock nut (Figure 32). Torque the lock nut to 20 to 27 N-m (15 to 20 ft-lb). 2.
Servicing the Roller bearings, bearing nuts, 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.
