Mulching Kit
The mulching kit consists of 3 baffles, a discharge cover and 10 carriage bolts and nuts.
Kits are HM600—39.55150 and HM720—39.55151 . To install the mulching kit, simply
turn the deck upside down or if mounted on the tractor (with park bake engaged and
ignition key removed), tilt the deck to the servicing position and install the kit according
to the drawing below.
NOTE: 1-The longest baffle goes in the center.
2-The deepest baffle goes to the left (discharge) side.
3-The saw-toothed edges will be facing the ground in mowing
position when installed.
4-Check for blade clearance. The saw-tooth edges should extend
beyond the end of the blade at least 1/4 inch. Slight reshaping of
baffles may be necessary for proper fit.
If the deck has been used, make sure it is clean before installation of parts. Blades do
not have to be removed for the installation but it is important that the blades are sharp
and in good condition. Low lift or mulch blades are recommended for mulching. Install
all parts before tightening the bolts. Once all parts are in place, tighten all ten bolts
(Torque to 14-16 ft/lbs.) A 1/2" box end wrench or socket drive is recommended in
order to tighten the bolts securely.
Mulching procedures may vary greatly due to climate, type of grass and soil conditions.
Some trial and error may prove helpful in getting the best results. In general it is best to
mow frequently and in dry conditions. Leaves are usually cut up and dispersed better
when some grass is cut in the mulching process. Generally a little more power is
required for mulching. When grass is tender, heavy, and/or wet, frequent deck cleaning
may be necessary. After mowing for a few minutes, turn the engine off, raise the deck,
and make a quick check on all ten bolts to assure that they are tight!
