Factor
Possible Problem/Correction
Bedknife to reel adjustment
Check bedknife to reel contact daily. The bedknife
must have light contact across the entire reel. No
contact will dull the cutting edges. Excessive contact
accelerates wear of both edges. Quality of cut is
adversely affected by both conditions (see Bedknife to
Reel Adjustment in the Cutting Unit Operator’s
Manual).
Slightly dull cutting edges may be corrected by
backlapping (see Backlapping in this chapter of this
manual).
Excessively dull cutting edges must be corrected by
grinding the reel and bedknife (see Preparing Reel for
Grinding in this chapter of this manual).
Rear roller adjustment
Height−of−cut
Adjust the rear roller brackets to hi or low position
depending on the height-of-cut range desired.
See Rear Roller Adjustment in the Cutting Unit
Operator’s Manual.
“Effective” or actual height−of−cut depends on the
cutting unit weight and turf conditions. Effective
height−of−cut will be different from the bench set
height−of−cut.
See Height−of−Cut Adjustment in the Cutting Unit
Operator’s Manual.
Proper bedknife selection for height−of−cut desired
Stability of bedbar
If the bedknife is too thick for effective height−of−cut,
poor quality of cut will result.
Make sure bedbar pivot bolts are seated securely.
Check condition of the bushings in the side plates.
See Bedbar Removal and Installation in this chapter of
this manual.
Number of reel blades
Use correct number of blades for clip frequency and
optimum height−of−cut range.
Cutting unit alignment and pull frame ground following Check pull frames and lift arms for damage, binding, or
bushing wear. Repair if necessary.
Roller condition
Make sure rollers rotate freely. Repair bearings as
necessary.
See Roller Bearing Replacement in the Service and
Repairs section in this chapter of this manual.
Cutting Unit drop speed and sequence
Rear cutting unit must drop after front cutting units.
See Rear Lift Cylinder Flow Control Valve in Chapter 4
