OPERATION
The safe operation of this machine is the
responsibility of the operator. The operator
should be familiar with the tractor and all at-
tachments that will be used before starting
operation. Refer to and read safety informa-
tion on pages 6 through 11.
CONTROLS AND SWITCHES
Know your controls and how to stop tractor,
engine and attachments quickly in an emer-
gency.
•
Stop tractor by moving steering levers
to neutral position (refer to section on
steering lever operation, page 19-20).
•
Stop engine by turning key to “OFF”
position.
•
Disengage power to attachments by
moving PTO switch to “OFF” (down)
position.
Operating this unit is not difficult once you
master the use of the controls. We recommend
you equip the tractor with the attachment you
will be using and practice in a fl at open area
at a medium throttle setting until you are com-
fortable with the controls.
Before operating this machine be
sure the operator-presence safety
system works. The engine should
not run without the operator in the
seat if the PTO switch is on or either
steering lever is in the run position.
Several safety switches are incorporated in
the unit’s design to prevent it from being start-
ed out of neutral or with the PTO engaged. All
controls must be in the “OFF” or neutral posi-
tion before the unit can be started. There is a
safety switch under the operator’s seat that
will cause the engine to stop should the oper-
ator leave the seat with any control engaged.
