DPA Cutting Unit Characteristics
Greensmaster 3120
17230SL Rev C
Never install or work on or near a cutting unit or cutting unit
suspension with the engine running. Always stop the engine and
remove the key before working on or near a cutting unit.
The dual point adjust (DPA) 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 this design gives
the necessary control to provide a continual self-sharpening action. This feature
maintains sharp cutting edges, assures good quality of cut and greatly reduces
the need for routine backlapping. In addition, the rear roller positioning system
allows for various height-of-cut ranges and aggressiveness of cut selections.
If a cutting unit is determined to be out of adjustment, complete the following
procedures in the specified order to adjust the cutting unit properly.
1.
Adjust the bedknife to reel contact; refer to the Cutting Unit Operator's
Manual.
Note: If one of the cutting unit side plates is removed during cutting unit
service or maintenance, check to make sure the rear roller is level (parallel
to the reel) before adjusting the rear roller; refer to
(page
7–12).
2.
Determine desired height-of-cut range and adjust the rear roller accordingly;
refer to the Cutting Unit Operator's Manual.
3. Adjust the height-of-cut; refer to the Cutting Unit Operator's Manual.
4. Adjust the cut-off bar; refer to the Cutting Unit Operator's Manual
