6.3.6 Driving the Windrower
WARNING
Before starting engine, securely fasten your
seat belt and ensure trainer’s seat belt is
fastened if occupied. The seat belt can help
insure your safety if it is used and
maintained.
WARNING
• Avoid driving the machine with header
removed. Removing header decreases
the weight on drive wheels, reducing
steering control.
• If necessary to drive machine with
header removed, use transmission "field
speed" range, do not exceed 1500 rpm
engine speed and avoid loose gravel and
slopes.
• Never use windrower as a towing vehicle
when header is removed, except as
instructed in Section 6.3.8.2 Towing
Header with Windrower. There is
insufficient weight on the drive wheels to
provide steering control.
• Because of windrower shape
characteristics, a roll-over protected
(ROPS) cab is not required. If operating
with header removed, be aware that the
cab structure will not withstand a roll-
over.
CAUTION
HYDROSTATIC STEERING
The machine is steered hydrostatically, that
is, turning the steering wheel varies the
hydraulic flow to one drive wheel relative to
the other drive wheel. The reaction of this
type of steering is different than
conventional steering mechanisms.
IMPORTANT
With the engine running, moving the
ground speed lever out of N-DETENT
unlocks steering. Any movement of
steering wheel will then cause the
machine to move, even if the ground
speed lever has not been moved forward
or rearward from the neutral position.
Hydrostatic steering is more sensitive than
mechanical steering.
Steering is opposite to normal when
driving in reverse.
The brakes are only on when the GSL is
in N-DETENT and the steering wheel is
centered and locked.
DANGER
• Never move ground speed lever or
steering wheel until you are sure all
bystanders have cleared the area.
• Be sure area is clear before making
turns, ends of header travel in a large
arc.
• Check the operation of all controls in a
safe, clear area before starting work. Be
sure you know the capacity and
operating characteristics of this machine.
• Do not allow riders in or on the machine.
• Operate only while seated in the
operator's position.
• Never attempt to get on or off a moving
windrower.
• Avoid sudden starts and stops.
