Factors That Can Affect Quality of Cut
There are a number of factors that can contribute to unsatisfactory quality of cut,
some of which may be turf conditions. The turf conditions such as the excessive
thatch, sponginess, or attempting to cut off too much grass height may not
always be overcome by adjusting the cutting unit or machine. It is important to
remember that the lower the height-of-cut, the more critical these factors are.
Remember that the effective or actual height-of-cut depends on the cutting unit
weight, tire pressures, hydraulic counterbalance settings, and turf conditions.
Factor Possible Problem/Correction
Maximum governed engine speed Check that the engine is running at the correct
high-idle speed.
Always mow at high engine speed.
Blade speed All the cutting unit blades should rotate at the
same speed.
Tire pressure
Check the air pressure of all the traction unit
tires. Adjust to the pressures specified in the
traction unit
Operator’s Manual .
Ensure that the rotary cutting unit
semi-pneumatic caster wheel tires are
not worn or damaged to the point they do not
hold air.
For Model 02835 flail mower, check the air
pressure of the pneumatic caster wheel tires.
Adjust to the pressure specified in the flail
mower
Operator’s Manual .
Blade condition Sharpen the blades if their cutting edges are
dull or nicked.
Inspect the blade sail for wear or damage.
Replace the blade if necessary.
Mower housing condition Ensure that the cutting chamber is in good
condition.
Keep the underside of the deck clean. The
unwanted material buildup can reduce the
cutting performance.
Height-of-cut Adjust the deck as specified in the cutting
unit
Operator’s Manual . The effective (actual)
height-of-cut may be different than the bench
set height-of-cut.
Cutting deck alignment and ground following Check the lift arms for wear, damage, or
binding. Also, inspect for bent or damaged
pivot shafts.
Roller and castor wheel operation All rollers and caster wheels should rotate
freely. Replace the bearings if they are worn
or damaged.
Grass conditions Mow when the grass is dry for best cutting
results. Also, remove only 2.5 cm (1 inch) or
1/3 of the grass blade when cutting.
Machine traction speed Mowing at too fast of a traction speed will
result in poor after cut appearance and missed
patches of grass.
