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,
uneven ground conditions, “sponginess” or attempting
to cut off too much grass height may not always be over-
come by adjusting the machine.
Remember that the “effective” or actual height−of−cut
depends on cutting unit weight, tire pressures, hydraulic
counterbalance settings, and turf conditions. Effective
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.
Maximum governed engine speed.
Check maximum governed engine speed. Adjust
speed to specifications if necessary.
2.
Blade speed.
All deck blades should rotate at the same speed.
See items in Troubleshooting Section of Chapter 4 −
Hydraulic System.
3.
4.
Tire pressure.
Check air pressure of each tire including castor tires.
Adjust to pressures specified in Operator’s Manual.
Blade condition.
Sharpen blades if their cutting edges are dull or nicked.
Inspect blade sail for wear or damage. Replace blade if
needed.
5.
Mower housing condition.
Make sure that cutting chambers are in good condition.
Keep underside of deck clean. Debris buildup will
reduce cutting performance.
6.
7.
Height−of−cut.
Make sure all cutting units are set at the same
height−of−cut. Set units as specified in the Operator’s
Manual.
Cutting unit alignment and ground following.
Check lift arms and cutting unit pivot linkages for wear,
damage, or binding. Also, inspect for bent or damaged
pivot shafts.
8.
9.
Roller and castor wheel condition.
Grass conditions.
All rollers and caster wheels should rotate freely.
Replace bearings if worn or damaged.
Mow when grass is dry for best cutting results. Also,
remove only 1” (2.5 cm) or 1/3 of the grass blade when
cutting.
