Troubleshooting; Factors That Can Affect Quality Of Cut - Toro Groundsmaster 3280-D Service Manual

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 cutting deck or machine.

Factors That Can Affect Quality of Cut

Factor
1. Maximum governed engine speed.
2. Blade speed.
3. Tire pressure.
4. Blade condition.
5. Mower housing condition.
6. Height−of−cut.
7. Cutting deck alignment and ground following.
8. Roller and castor wheel condition.
9. Grass conditions.
Groundsmaster 3280−D/3320
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.
Possible Problem/Correction
Check maximum governed engine speed. Adjust
engine speed to specifications if necessary (see
Chapter 3 − Gasoline Engine or Chapter 4 − Diesel
Engine).
All cutting deck blades should rotate at the same
speed.
Check air pressure of all tires including castor tires.
Adjust to pressures specified in Operator's Manual.
Sharpen blades if their cutting edges are dull or nicked.
Inspect blade sail for wear or damage. Replace blade if
needed.
Make sure that cutting chamber is in good condition.
Keep underside of deck clean. Debris buildup will
reduce cutting performance.
Make sure all cutting deck height−of−cut adjustments
are the same. Adjust deck as specified in the Cutting
Unit Operator's Manual.
Check lift arms for wear, damage or binding. Also,
inspect for bent or damaged pivot shafts.
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.
