OPERATION
Driving the Windrower
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 half maximum engine
speed and avoid loose gravel and slopes.
· Never use windrower as a towing vehicle
when header is removed. 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.
Remember:
· With the engine running and the variable
speed lever in neutral, the machine will
move if the steering wheel is turned.
· Hydrostatic steering is more sensitive than
mechanical steering.
· Steering is opposite to normal when driving
in reverse.
CAUTION: 1. Never move variable
speed lever or steering wheel until
you are sure all bystanders have
cleared the area.
2. Be sure area is clear before making turns,
ends of header travel in a large arc.
3. 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.
4. Do not allow riders in or on the machine.
5. Operate only while seated in the operator's
position.
6. Never attempt to get on or off a moving
windrower.
7. Avoid sudden starts and stops.
8. Avoid inclines, ditches and fences.
9.
Reduce speed when turning, crossing
slopes, or travelling over rough ground.
10. Do not allow anyone to stand behind the
machine while operating. Foreign objects
may be forcibly ejected.
