Service Dealer’s Guide to Great Quality of Cut 5 - 3
Troubleshooting Quality of Cut
7. Verify that there is not a gage wheel or roller
pushing the grass down before the blade can cut
it.
8. Excessive toe in on front tires can push the grass
down to the point where the mower might have
difficulty pulling it up to cut it. Check and adjust as
needed.
9. Blades that are short or have worn sails do not
provide the air flow to stand the grass up. Replace
worn blades.
10. The grass may be compacted after being cut. The
rear tires and rollers or gage wheels on the rear of
the mower will knock the grass down, too. What
may appear to be a streak may be grass that the
tires or gage wheels did not hit. If so, the rest of
the grass will straighten up in a day or so and the
lawn will be level. To test for this, brush the grass
with your hand to see if it is level. If so, the
problem could be compaction. This occurs
frequently when the grass is too wet or too dry.
11. On multi-blade decks, what is described as a
streak can result from two of the blades not being
aligned, and therefore cutting at two different
heights; this is actually a stair step cut. On multiple
blade mowers the blade tips should be in line
within 1/8 inch. See the operator's manual or the
section "Checking and Adjusting the Blade Level"
of this manual for instructions on checking and
repairing this problem.
Uncut Grass
1. Verify the correct blade is being used. Some
models have different blades for mulching versus
bagging.
2. Check the blade pitch. See the Operator's Manual
or the section "Checking and Adjusting the Blade
Level" of this manual for adjustment instructions.
3. Try a lower height of cut and slower ground
speed.
Windrow
1. Wet or extremely lush grass windrowing can
usually be resolved by following the general
suggestions.
2. Dry grass windrowing indicates the operator is
trying to process too much grass at one time. One
or more of the general suggestions should resolve
this problem.
3. If side discharging, ensure grass is being thrown
into the previously-cut area.
