GENERAL OPERATION
Operation - 30
Weight Transfer
The weight transfer system transfers weight from the
attachment to the front wheels of the power unit when
the front hitch is in float or assists in lifting the attach
-
ment. Transferring weight from the attachment to the
power unit increases the traction control, improves
hillside maneuverability, aids in lifting the attachment,
reduces steering effort, and lessens the attachment
resistance when in contact with the ground.
The operator can select different transfer rates by
selecting one of the four positions from no weight
transfer (0) to maximum weight transfer (3). Set the
weight transfer to 0 when attaching or detaching any
attachment.
To set the weight transfer, raise the front hitch to
its maximum height and move the weight transfer
select lever to the desired position.
Selecting the proper amount of weight to transfer
depends on attachments, ground conditions, and
operator preference. A lightweight attachment (e.g.
LA162 power blower) will not go down with full
weight transfer on. With full weight transfer on, and
mowing in the float position, the mower may not
come down quickly enough when going through
uneven terrain. Power unit speed or weight transfer
rate must be reduced.
Roll-Over Protection System (ROPS)
WARNING
Keep the ROPS locked in the upright position and
the seat belt securely fastened during operation.
Failure to do so could result in serious injury or
loss of life.
The 3400 is equipped with a fold down ROPS that
allows the power unit to access areas of low over-
head clearance. Lower the roll bar only when abso-
lutely necessary and raise the roll bar to the upright
position as soon as clearance allows.
WARNING
Do not wear a seat belt when the roll bar has
been lowered to the down position.
To lower the roll bar:
1. Remove the pins from the front holes (1) of the
right and left hinge plates.
2. Fold the roll bar down and install the pins in the
rear holes (2) of the hinge plates to lock in place.

To raise the roll bar:
1. Remove the pins from the rear holes (2) of the
right and left hinge plates.
2. Raise the roll bar to the upright position and install
the pins in the front holes (1) of the hinge plates to
lock in place.
12 Volt 4-Pin Auxiliary Outlets (Optional
Accessory)
Certain attachments require a 12 volt auxiliary
outlet. Plug the attachment’s 12 volt power cord into
the 12 volt 4-pin outlet. The actions of the front 12
volt outlet are controlled by an on/off switch and two
momentary on buttons on the SDLA handle. The
actions of the rear 12 volt outlet are controlled by an
on/off switch and a momentary on/off/on switch on
the side dash panel beside the SDLA control. The
momentary buttons or switch are used for control-
ling movement that is only used for a brief time. The
on/off switches are used to activate equipment or
select different functions.
