Revision A
Spin Turning
Hydrostatic steering provides significantly more maneuverability than mechanical steering.
CAUTION
Be sure area is clear before making turns. Although windrower pivots on the spot, the ends of the header travel faster
and in a large arc.

1. Move the ground speed lever (GSL) (A) out of PARK towards
the seat and hold.
2. Slowly turn the steering wheel in the desired direction of
turn. The windrower will pivot between the drive wheels.
3. To increase the turn radius, slowly move the GSL away from
NEUTRAL. Remember that this will increase ground speed
as well.
4. To stop the turn, slowly turn the steering wheel back to its
centered position.
Stopping
CAUTION
Park on a flat, level surface with the ground speed lever in PARK position and the steering wheel in locked position
(centered). Wait for the HPT to beep and display a red P symbol to confirm the park brakes have engaged.
WARNING
Do NOT move ground speed lever rapidly back to NEUTRAL. You may be thrown forward by a sudden stop and wheels
may skid, reducing steering control. Always wear a seat belt when operating windrower.

five minutes to cool hot engine parts (and allow
turbocharger to slow down while engine oil pressure is
available).

Avoid unnecessary idling. Stop the engine if it will be idling
for longer than five minutes.
NOTE:
Brakes are automatically engaged when steering wheel is
locked in PARK position.
