Characteristics

CAUTION

Never install or work on the cutting units or lift arms with the engine running. Always stop en- gine and remove key first.

The dual knob bedknife–to–reel adjustment system in- corporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing perfor- mance. The precise adjustment possible with this de- sign 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 two height-of-cut ranges.

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 parallel to the reel.

2.Determine desired height of cut range and install rear roller mounting shim accordingly.

3.Adjust the height-of-cut.

4.Adjust the cut-off bar.

See Cutting Unit Operator’s Manual for adjustment pro- cedures for the cutting units on the Greensmaster 3150.
