Troubleshooting
There are a number of factors that can contribute to un-
satisfactory quality of cut, some of which may be turf
conditions. Turf conditions such as excessive thatch,
“sponginess” or attempting to cut off too much grass
height may not always be overcome by adjusting the
mower. It is important to remember that the lower the
height–of–cut, the more critical these factors are. See
Adjustments and Service and Repairs sections for de-
tailed adjustments and repair information.
Factors That Can Affect Quality of Cut
Factor Possible Problem/Correction
Governed engine speed Check maximum governed engine speed. Adjust
engine to specifications if necessary.
See Adjustments section in Chapter 3 – Engine.
Reel bearing condition Check and replace bearings if necessary. Make sure
bearing housings are secured properly.
See Reel and Reel Bearings in the Service and
Repairs section.
Reel and bedknife sharpness A reel and/or bedknife that has rounded cutting edges
or ”rifling (grooved or wavy appearance) cannot be
corrected by tightening the bedknife to reel contact.
Grind reel to remove taper and/or rifling. Grind
bedknife to sharpen and/or remove rifling.
The most common cause of rifling is bedknife to reel
contact that is too tight.
A new bedknife must be ground or backlapped
after installation to the bedbar.
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).
Slightly dull cutting edges may be corrected by
backlapping (see Backlapping).
Excessively dull cutting edges must be corrected by
grinding the reel to and bedknife (see Preparing Reel
for Grinding).
Drum parallel to reel Check and adjust as necessary. The Drum must be
leveled so it is parallel with the reel before setting the
height–of–cut.
See Leveling Rear Drum to Reel in Adjustments
section.
