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
machine. It is important to remember that the lower the
height of cut, the more critical these factors are.
Remember that the “effective” or actual height of cut de-
pends on cutting unit weight and turf conditions. Effec-
tive height of cut will be different than the bench set
height of cut.
Factors That Can Affect Quality of Cut
Factor Possible Problem/Correction
1. Engine maximum governed speed. Check maximum governed engine speed. Adjust
speed to specifications if necessary. If engine is not
running at specified maximum governed RPM, reel
speed settings may not match ground speed.
2. Reel speed and ground speed. Adjust reel speed to setting shown on REEL SPEED
SETTINGS graph for the number of reel blades (5 or 8)
and the desired ground speed (see Operator”s
Manual).
All reels should rotate at about the same speed. All
cutting units should have equal bedknife to reel
contact. If checking RPM, do not run reel too long
without cutting grass, or bedknife and/or reel may
overheat and “rifle”.
See other items in Troubleshooting section of Chapter
4 – Hydraulic System.
3. Cutting unit counter balance tension adjustment.
The counter balance spring on each cutting unit lift arm
can be adjusted to compensate for different turf
conditions. Decreased counter balance tension will
help keep the cutting units on the ground when
mowing at higher speeds, and it helps maintain a
uniform height of cut in rough conditions or in areas of
thatch build up. Increased counterbalance tension will
improve traction by increasing weight on the front tires.
Also, the spring may be adjusted at the cutting unit
pivot point. Raising the spring at the lift tab decreases
the cutting unit weight at the outboard end. Lowering
the spring at the lift tab increases the cutting unit
weight at the outboard end.
NOTE: Decreased counter balance tension may lower
the actual or ”effective” height of cut.
4. Tire pressure. Check each tire’s pressure. Adjust to pressures
specified in Specifications section of Chapter 6 –
Wheels and Brakes.
