Troubleshooting; Factors That Can Affect Quality Of Cut - Toro Groundsmaster 4100-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 machine.

Factors That Can Affect Quality of Cut

Factor
1. Maximum governed engine speed.
2. Blade speed.
3. Tire pressure.
4. Cutting 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.
Cutting Deck
Remember that the "effective" or actual height--of--cut
depends on cutting deck weight, tire pressures, hydrau-
lic 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
speed to specifications if necessary (see Chapter 3 --
Kubota Diesel Engine).
All deck blades should rotate at the same speed.
See items in Troubleshooting Section of Chapter 4 --
Hydraulic System.
Check air pressure of each tire including castor tires.
Adjust to pressures specified in Operator's Manual.
Sharpen cutting blades if their cutting edges are dull or
nicked.
Inspect blade sail for wear or damage. Replace blade if
needed.
Make sure that cutting chambers are in good condition.
Keep underside of deck clean. Debris buildup will
reduce cutting performance.
Make sure all deck height--of--cut adjustments are the
same. Adjust deck as specified in the Operator's
Manual.
Check lift arms and cutting deck pivot linkages for
wear, damage or binding. Also, inspect for bent or
damaged pivot shafts.
All rollers and caster wheels should rotate freely.
Replace bearings, shafts or rollers if worn or damaged.
Mow when grass is dry for best cutting results. Also,
remove only 1" (25 mm) or 1/3 of the grass blade when
cutting.
