Proper Mulching
Mulching consists of a mower deck which cuts and recuts
clippings into tiny particles and which then blows them
down INTO the lawn. These tiny particles decompose rapidly
into by-products your lawn can use. UNDER PROPER
CONDITIONS, your mulching mower will virtually eliminate
noticeable clippings on the lawn surface.
NOTE: When mulching under heavy cutting conditions, a
rumbling sound may be present and is normal.
Mulching Requires EXCELLENT Mowing Conditions
Mulching mowers cannot function properly if the grass is
wet, or if the grass is simply to high to cut. Even more than
normal mowing, mulching requires that the grass be dry and
the appropriate amount is cut.
Do not use the mower as a mulching mower during the first
two or three mowings in the spring. The long grass blades,
quick growth, and often wetter conditions are more suitable
for broadcasting (side-discharging) or grass bagging
operation.
Engine Speed & Ground Speed for Mulching
Use full engine throttle matched with a slow ground speed
so that clippings will be finely cut. Ground speed while
mulching should be HALF of the speed that would be
used when broadcasting (side discharging) under similar
conditions. Since mulching requires more horsepower
than broadcasting, using a slower ground speed is vitally
important for proper mulching operation.
How Much Grass to Mulch
The best mulching action typically results from cutting only
the top 1/2 inch to 3/4 inch of grass blade. This provides
short clippings which decompose properly (much more
quickly than longer clippings). The ideal cutting height will
vary with climate, time of year, and quality of your lawn. We
recommend that you experiment with both the cutting height
and ground speed until you achieve the best cut. Start with
a high cutting height and using progressively lower settings
until you find a cutting height that is matched to your
mowing conditions and preferences.
