Factors That Can Affect Cutting Performance
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.
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. Anti--scalp roller condition.
9. Grass conditions.

Remember that the "effective" or actual height--of--cut
depends on cutting deck weight and turf conditions.
Possible Problem/Correction
Check maximum governed engine speed. Adjust
engine speed to specifications if necessary (see
Chapter 3 -- Kubota 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 deck cutting chamber is in good
condition.
Keep underside of deck clean. Debris buildup will
reduce cutting performance.
Adjust deck as specified in the Operator's Manual.
Effective (actual) height--of--cut will be different than
the bench set height--of--cut.
Check lift arms for wear, damage or binding. Also,
inspect for bent or damaged pivot shafts.
Cutting deck adjustment should allow the rear of the
blade plane to be 5/16" (8 mm) higher than the front of
the blade plane.
All anti--scalp rollers should rotate freely. Replace
rollers or roller shafts 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.
