Operation

Attachments

This unit can use many different attachments.
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

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.
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. Depress 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.
