ATTACHMENTS
This unit can use many different attachments. See the attachment
page in this book. This unit can pull attachments like a lawn
sweeper, a lawn aerator, a hopper spreader or a small trailer. This
unit can not use attachments that engage the ground like a plow, a
disk harrow, or a cultivator.
For all pull
−
behind attachments or trailers, the maximum gross
weight is 250 pounds. Gross weight is the weight of the attachment
or trailer and any load that might be on or in it.
Do not operate on a slope that is greater than 10 degrees when
using a pull
−
behind attachment or trailer. We have included a slope
guide in this book to help you determine the slope on which you will
be operating your unit. Never allow someone to stand or ride on or
in an attachment or trailer.
ELECTRICAL SAFETY SYSTEM
The electrical system has three primary components; an Operator
Presence System, a Select Reverse
t
System, and a Run-Mow
System.
Operator Presence System (Seat)
The seat has an Operator Presence System to shut off the engine
when the operator leaves the seat. This system is not intended for
regular use in stopping the engine or the blade(s). Before leaving the
seat, move the blade rotation control to the DISENGAGE position,
shift to neutral, set the parking brake and stop the engine.
Select Reverse
t
System
The
Select Reverse
t
system will allow the mower blade(s) to
continue to rotate when traveling in reverse. See “How To Operate
The Ignition Key Switch” and “How To Start The Engine” for further
details.
How To Check The Safety Interlock Switches
To check the function of the safety interlock switches, follow the
steps below.
1. Check the
blade rotation control
switch.
Sit in the seat. De-
press the clutch/brake pedal. Move the blade rotation control to
the ENGAGE position. Turn the ignition switch to the START
position. The engine should not start. If the engine starts, the
switch is defective and must be replaced.
2. Check the
clutch/brake switch.
Sit in the seat. Move the
blade rotation control to the DISENGAGE position.
DO NOT
depress the clutch/brake pedal. Turn the ignition switch to the
START position. The engine should not start. If the engine
starts, the switch is defective and must be replaced.
3. Check the
Operator Presence System switch.
DO NOT
sit
in the seat. Depress the clutch/brake pedal. Move the
blade
rotation control
to the DISENGAGE position. Turn the ignition
switch to the START position. The engine should not start. If
the engine starts, the switch is defective and must be replaced.
4. Check the
Select Reverse
t
switch.
Sit in the seat. Depress
the clutch/brake pedal. Move the blade rotation control to the
DISENGAGE position. Start the engine and move the drive
control to the reverse (R) position. With the engine running,
move the blade rotation control to the ENGAGE position. The
engine should stop running. If the engine continues to run, the
Select Reverse
t
switch
is defective and must be replaced.
HOW TO OPERATE THE IGNITION KEY SWITCH
Use the ignition key switch to start and stop the engine. When you
start the engine and release the ignition key, the ignition key switch
will automatically default to the recommended RUN
−
MOW position
for normal mowing.
START
−
Use this position to start the engine.
RUN-MOW
−
When you start the engine and release the ignition
key, the ignition key switch will automatically default to the
recommended
RUN-MOW
position for normal mowing. In the
RUN-MOW
position, the system will stop the engine and the
blade(s) when the speed control pedal/shift lever is put in the
reverse position.
SELECT REVERSE
t
−
The optional
Select Reverse
t
position will allow the mower blade(s) to continue to rotate when
traveling in reverse. Always go back to the recommended
RUN-MOW position for normal mowing when operation in
Select
Reverse
t
is not absolutely necessary. NEVER use the
Select
Reverse
t
option if children are on or near the property.
WARNING: Operators are strongly discouraged
from using this option unless the operator de-
cides such operation is absolutely necessary and
that safe precautions are taken. Never use the Select Re-
verse
t
option if children are on or near the property. Always
look down and behind before and while backing. After using
the Select Reverse
t
position, move the ignition key back to
the RUN-MOW position.
