Loosely install the 2 reel motor mounting cap screws to the left side plate of the cutting unit (Figure 7).
Product Overview Specifications Tractors These cutting units will mount on the Reelmaster 5510 & 5610 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 9 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. 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. Note: The position of the rear roller to the reel is controlled by the machining tolerances of the assembled components and paralleling is not required.

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 14). Figure 16 Figure 14 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 18) 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 19). Figure 19 1.
Maintenance Lubrication Each cutting unit has (6) grease fittings (Figure 21) that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. Figure 22 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 25). Figure 27 1. Bedbar bolt 2. Nut 3.
