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
Factors That Can Affect Quality of Cut
Factor
Tire pressure
Governed engine speed
Reel bearing condition
Reel and bedknife sharpness
Bedknife to reel adjustment

cutting unit. 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
detailed adjustments and repair information.
Possible Problem/Correction
Check pressure of all tires. Pressure must be equal on
both front tires. Adjust pressure as necessary.
See General section in Chapter 6 – Wheels and
Brakes.
Check maximum governed engine speed. Adjust
engine to specifications if necessary.
See Adjustments section in Chapter 3 or 4 – Vanguard
or Perkins Engine.
Check bearings for wear and replace if necessary.
Make sure bearing housings are secured properly.
Keep bearings well lubricated.
See Reel and Bearing Removal and Installation.
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.
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 and bedknife (see Preparing Reel for
Grinding).
