Operation & Care
CHECKS BEFORE EACH USE
1. Check the mower and grass catcher to be sure they
are properly installed and all nuts, bolts and pins
are securely fastened.
A WARNING
Never operate the mower unless the mower deflec¬
tor or the entire grass catcher is completely install¬
ed.
2. Clear the lawn of all sticks, stones, wire and other
debris which may be caught or thrown by the
mower blades.
OPERATING THE GRASS CATCHER
^ WARNING
Do not work around the mower housing or grass
catcher until you are certain that the mower blades
have stopped rotating.
Never operate the unit with the grass bag cover or
discharge tube removed.
Also see warnings on page. 6.
The grass catcher collects grass or leaves as they are
discharged from the mower. It is operated by running the
tractor and mower. Consult the tractor operator’s manual
if you have any questions on tractor and mower opera¬
tion.
During operation, it is necessary to check the bag
contents at intervals. If the bag is full or nearly full, empty
it as described in "Empty the Grass Catcher". Otherwise,
the bag can overfill and quickly cause filling and plugging
of the discharge tube and mower.
Filling of the bag or plugging of the mower is easily
detected if the tube is kept reasonably clean. Simply
watch the flow of grass through the tube (occasionally) as
you mow. Always watch for objects in direction of travel.
Best results will usually be obtained with engine set at full
throttle. When the grass is heavy, run the engine at full
Speed and slow down the tractor ground speed.
Do not try to collect damp or wet grass. Wet grass will
stick to the mower. Wait until dew or rain has evaporated
before mowing.
When collecting leaves or mowing tall grass, raise the
mower to highest cutting height and make one pass over
the area to be cleared. Then lower the mower and make a
second pass to complete the mowing. In extremely tall or
heavy grass, it may also be necessary to cut only half the
width of the mower to prevent clogging of the mower and
discharge tube.

Operation & Care
EMPTY THE GRASS CATCHER
A WARNING
Before emptying grass catcher, always stop tractor,
disengage mower PTO drive, apply parking brake,
stop engine and remove key.
To empty the grass catcher, pull up on cover to unsnap
clips. Remove cover and set it aside. Then lift grass bag
assembly off hanger, folding bag back as necessary to
clear discharge tube. Turn bag assembly over to empty it
and then reinstall it on hanger. Tap cover a few times to
remove any material on the inside. Then place cover back
over bag assembly and push it firmly to lock clips to bag
frame.
AFTER EACH USE
After each use, empty the grass catcher as described
above. If the bag is wet, dry it. Store the grass catcher on
or off the tractor in a dry, enclosed area.
A WARNING
Never operate on slopes greater than 30 percent
(16.7°) which is a rise of three feet vertically in 10
feet horizontally.
£k WARNING
When mowing with the grass catcher, always use
the front counterweight.
A CAUTION
Do not allow gasoline or other petroleum products
to come in contact with the plastic grass discharge
tube. These products will cause the tube to become
brittle and crack.
OFF-SEASON STORAGE
To protect your grass catcher, store it in an enclosed dry
area. If stored in a garage, keep the bag assembly on a
shelf or hang it on a wall where the bag will not come in
contact with water or melted snow. Store the cover and
grass discharge tube in a similar manner to prevent
breakage. Clean the unit to remove all grass and dirt.
Coat all bare metal surfaces with paint or a light coat of
oil to prevent rusting.
A WARNING
When operating on slopes that are greater than 15
percent (8.5°) but less than 30 percent use rear
wheel weights (see your dealer). Use slow ground
speeds. Mow up and down the face of slopes and
never across the fact. Use caution when changing
directions and DO NOT STOP OR START.
