The maximum weight of a towed trailer should be 
less than 300 lbs (138kg).  Secure the trailer with an 
appropriately sized clevis pin (A, Figure 9) and clip 
(B).

Excessive towed loads can cause loss of traction 
and loss of control on slopes.  Reduce towed weight 
when operating on slopes.  The surface being driven 
on greatly impacts traction and stability.  Wet or 
slippery surfaces can greatly reduce traction and the 
ability to stop or turn.  Carefully evaluate the surface 
conditions before operating the unit and trailer, and 
never operate on slopes greater than 10°.  See 
SLOPE OPERATION and TOWED EQUIPMENT in 
the safety section of this manual for additional safety 
information.

Operation

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 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 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. 

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.

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.
