3-2 Operation And Tips On Mowing
To check the operation of the safety interlock harness
perform the following:
A. Start mower
B. While seated in the operator’s seat, rotate the
engagement handle of the collection system away
from the mower.
C. With the blower engaged, stand up from the
operator’s seat.
If the mower does not shut off, turn off mower
and refer to page 7 to verify proper installation of the
harness. If problem persists contact your local dealer.
Only qualified people familiar with this operator’s manual
and the mower’s operator’s manual should operate this
machine.
A. Perform BEFORE EACH USE the maintenance list in
paragraph 4-1.
B. Start mower.
C. With the mower at high idle speed, engage the mower
deck.
D. While seated in the operator’s seat, rotate the
engagement handle of the collection system away
from the mower. Continue to rotate the handle until it
stops in an over center position. With the blower
engaged, you can proceed to operate the control
levers of the mower.
If the collection system does not appear to be
collecting the grass clippings, disengage the deck
and blower, then, engage the parking brake and turn the
mower off. Proceed to section 3-3, and review the
section 2-6, in this manual.
This action will shut off the mower
which verifies proper installation of the harness.
D. Check the mower’s safety interlock, see mower’s
manual for more detail.
To obtain the maximum effectiveness from your
collection system the tips listed below should be
followed:
* Watch your speed- Normal conditions will allow a
speed of up to approximately 5 mph, but thick, heavy
damp conditions will require reduced ground speed.
* Mow with sharp blades- A sharp blade cuts cleaner.
* Wet grass and leaves will decrease effectiveness and
will increase horsepower requirements.
* Mow at higher cutting heights- Remove and mulch no
more than 2” of grass length with each mowing.
(Experts recommend not cutting off more than 1/3 of
the grass blade length at any given time.)

OPERATING INSTRUCTIONS
* Mow twice, at different height settings, (high, then low),
if grass is extra tall.
* Remember that horsepower requirements will vary with
the mowing conditions such as type and height of turf
grass, moisture content, amount of leaves, whether the
terrain is flat or hilly, etc.
A. To disengage the blower, rotate the engagement
handle towards the mower.
3-3 Disengagement Of The Blower
WARNING:
NOTE:
NOTE:
The blower will continue to spin. DO NOT
TOUCH the blower, pulleys, or the belt until the tractor is
turned off. DO NOT adjust the belt tension until the
mower is turned off. Refer to section 2-6 of the manual.
To determine when the collection bags are full,
follow the following steps:
A. Stop the forward movement of the mower.
B. Disengage the mower deck.
C. Disengage the blower.
D. Engage the parking brake.
E. Once the parking brake has been engaged, then and
only then, walk behind the mower and check the
collection bags by lifting the plastic hood. Load in
bags should not exceed the height of the installed
bag.
F. To release bags from frame, lift bag ring from tab on
bagger frame, slide bag out and turn bags over to
deposit clippings.
G. Follow steps on page 14 to re-attach bags back to the
bagger.
Do not allow collection bags to become over-
filled as potential damage may occur to your
equipment. Also, be sure to clean the hood screen as
needed.
Before each use:
1. Check blades and spindles to be sure that no foreign
objects, such as wire or steel strapping bands, are
wrapped around them.
2. Inspect blades for wear. Replace if necessary. If it is
necessary to sharpen the blades, remove the blades
from the spindles before sharpening. DO NOT
sharpen blades while still attached to the mower.
