Troubleshooting; Factors That Can Affect Quality Of Cut - Toro Groundsmaster 3505-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,
"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.

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 unit alignment and ground following.
8. Roller condition.
Cutting Units
Remember that the "effective" or actual height--of--cut
depends on cutting unit weight and turf conditions. Ef-
fective 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.
All deck blades should rotate at the same speed.
See items in Troubleshooting Section of Chapter 4 --
Hydraulic System.
Check each tire's pressure. Adjust to pressures
specified in Traction Unit 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 chambers are in good condition.
Keep underside of deck clean. Debris buildup will
reduce cutting performance.
Make sure all cutting units are set at the same
height--of--cut. Set units as specified in the Cutting Unit
Operator's Manual.
Check lift arms and cutting unit pivot linkages for wear,
damage or binding. Also inspect for bent or damaged
pivot shafts.
All rollers should rotate freely. Replace bearings if worn
or damaged.
