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.
Figure 6 Figure 4 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 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.

Cap screw 6 Adjusting the Rear Shield Mount the Counter Weights No Parts Required No Parts Required Procedure Procedure Under most conditions, best dispersion is attained when the rear shield is closed (front discharge). When conditions are heavy or wet, rear shield may be opened. All cutting units are shipped with the counter weight mounted to the left end of the cutting unit.
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.
8 Adjust the Turf Compensation Spring No Parts Required Procedure Tractors are setup at the factory appropriately for most fairway mowing applications. Figure 14 1. Lift chain The following adjustments are available for fine-tuning of the machine to the application: 2. Snapper pin The Turf Compensation Spring (Figure 16) transfers weight from the front to rear roller. This helps to reduce a wave pattern in the turf, also known as bobbing. 8. Coat the spline of the reel motor with clean grease. 9.
Note: As gap (C) between spring bracket and washer increases, cutting unit ground clearance decreases and carrier frame/cutting unit rotation angle (B) increases.
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) 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. Note: All accessories and kits are 1 per cutting unit unless otherwise specified. Grass Basket Kit: A series of clipping collection baskets attached to the front of the cutting units to collect grass clippings.
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 18 4. Check for light contact at other end of reel using paper and adjust as required. 5.
6. Re-secure roller bracket and spacers to underside of side plate mounting flanges with nuts previously removed. 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. 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 22). Figure 24 Figure 22 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 26) 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.
Maintenance Lubrication Each cutting unit has (6) grease fittings (Figure 27) that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. Figure 28 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 31). Figure 33 1. Bedbar bolt 2. Nut 3.
