OPERATOR’S STATION
3.2 Operator Presence System
The Operator Presence System is a safety feature designed to deactivate or alarm selected systems when
the Operator is not seated at the operator’s station.
These systems include:
• Header Drive
• Engine and Transmission
3.2.1 Header Drive
• Requires the Operator to be seated in the seat in order to engage the header drive.
• Power is maintained to the header drive for five seconds after the Operator leaves the seat, and then the header
shuts down.
• After the header has shut down automatically, the HEADER DRIVE switch must be moved to OFF position and
back to the ON position again to restart the header.
3.2.2 Engine and Transmission
• The engine will not start when the HEADER DRIVE switch is engaged.
• The engine will shut down when the windrower is moving at 5 mph (8 km/h) or less and the Operator leaves the
seat. The CDM will flash “NO OPERATOR” on the upper line and “ENGINE SHUT DOWN 5...4...3...2...1...0” on
the lower line accompanied by a steady tone. At “0”, the engine shuts down.
• If the Operator leaves the seat and the transmission is not locked in NEUTRAL, after five seconds the lower
display will flash “NOT IN NEUTRAL” and an alarm will sound.
• When the seat is in between cab-forward and engine-forward positions, the engine will shut off if the transmission
is not locked in the NEUTRAL position. The lower display will flash “LOCK SEAT BASE” until the seat base is
locked into position.
