1 Inspection Parts needed for this procedure: 1 Cutting unit Procedure Figure 3 After the cutting unit is removed from the box, inspect the following: 1. Pivot rod 1. Check each end of the reel for grease. Grease should be visibly evident in the reel bearings and internal splines of the reel shaft. 2. Tipper support bracket w/roller Note: The tipper bracket w/roller and the tipper support brackets are not required when operating the DPA cutting units (Figure 3). They may be removed if desired. 2.
the bracket should be rotated to the left 10 degrees from vertical (Figure 4). Figure 6 4. Tighten all the U-bolt nuts to 38–48 ft-lbs. 5. Mount a lift chain to each chain bracket with a screw, washer and nut, positioning as shown in Figure 7 Figure 4 2. On lift arms #2 and #3, position the brackets and U-bolts 15 inches behind the center line of the pivot knuckle (Figure 5). Rotate the brackets 45 degrees to the outboard side of the machine. Figure 7 1. Lift chain 2.
sure the nuts on the back end of the bedbar adjusting screws are not resting on the work surface (Figure 8). Figure 9 1. Rear shield 2. Cap screw Figure 8 1. Cutting unit kickstand 6 5 Mount the Counter Weights Adjusting the Rear Shield No Parts Required No Parts Required Procedure All cutting units are shipped with the counter weight mounted to the left end of the cutting unit. Use the following diagram to determine the position of the counter weights and reel motors.
7 Installing the Cutting Units Parts needed for this procedure: 5/7 Large O-ring Procedure 1. Insert a thrust washer onto horizontal shaft of pivot knuckle as shown in Figure 13. Figure 11 1. Counter weight 2. On right end of cutting unit, remove the plastic plug from the bearing housing (Figure 12). 3. Remove the 2 cap screws from the right side plate (Figure 12). Figure 13 1. Carrier frame 2. Pivot knuckle 3. Lift arm steering plate 2.
Figure 14 1. Lift chain 2. Snapper pin 8. Coat the spline of the reel motor with clean grease. 9. Oil the reel motor O-ring and install it onto the motor flange. 10. Install the motor by rotating it clockwise so that the motor flanges clear the cap screws (Figure 15). Rotate the motor counterclockwise until the flanges encircle the cap screws then tighten the cap screws Important: Make sure the reel motor hoses are not twisted, kinked or in the risk of being pinched. Figure 15 1. Reel drive motor 2.
Product Overview Specifications Tractors These cutting units will mount on the Reelmaster 6500 & 6700 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 .250 inch (3 mm) to 1.00 inch (25 mm). Bench height of cut range with the High Height of Cut Kit installed is 1.00 inch (25 mm) to 2.00 inches (51 mm).
Cutting Unit Accessories and Kits (see parts catalog for part numbers) however, effective height of cut is raised and quality of cut is reduced. Scrapers (Wiehle, Shoulder, Rear roller, Full Front Roller): Fixed scrapers for all optional rollers are available for reducing grass build up on rollers which can affect height of cut settings. Roller Rebuild Kit: Includes all the bearings, bearing nuts, inner seals and outer seals required to rebuild a roller.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Adjustments Adjusting the Bedknife to the Reel Bedknife to reel adjustment is accomplished by loosening or tightening bedbar adjusting screws, located on top of mower. Figure 17 4. Check for light contact at other end of reel using paper and adjust as required. 5.
Paspalum, Zoysia) while cool season grasses (Bent, Bluegrass, Rye) may require normal to more aggressive setups. More aggressive setups cut more grass off by allowing the spinning reel to pull more grass up into the bedknife. 6. Re-secure roller bracket and spacers to underside of side plate mounting flanges with nuts previously removed. 7. Verify that bedknife to reel contact is correct. Tip mower to expose front and rear rollers and bedknife.

Adjusting the Height of Cut Note: For heights of cut greater than 1.00" the High Height of Cut Kit must be installed. 1. Loosen locknuts securing height-of-cut arms to cutting unit side plates (Figure 21). Figure 23 Figure 21 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. Adjusting screw 1. Height-of-cut arm 2. Locknut 2.
Cutting Unit Characteristics Note: Over time, the chamfer (Figure 25) will need to be reground as it is only designed to last 40% of the bedknife life. The dual knob bedknife-to-reel adjustment system incorporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing performance.
Note: The recommended top and front bedknife grind angle is 3 to 7 degrees (Figure 26). Figure 26 1.
Maintenance Lubrication Each cutting unit has (6) grease fittings (Figure 28) that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. Figure 29 The lubrication points are front roller (2), rear roller (2) and reel bearing (2). 1. Bedknife adjusting knob Note: Lubricating cutting units immediately after washing helps purge water out of bearings and increases bearing life. 2.
Note: Reel bearings do not require preload. Over tightening reel bearing adjuster nut will damage reel bearings. 4. Retighten set screw securing bearing adjusting nut to bearing housing. Torque to 12-15 in-lb. Servicing the Bedbar Removing the Bedbar 1. Turn bedbar adjuster screws, counterclockwise, to back bedknife away from reel (Figure 32). Figure 34 1. Bedbar bolt 2. Nut 3.

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 distributor for assistance. A Roller Rebuild Kit, Part No. 114–5430 and a Roller Rebuild Tool Kit, Part No. 115–0803 (Figure 36) are available for servicing the roller. The Roller Rebuild Kit includes all the bearings, bearing nuts, Figure 36 1. 2. 3.
