safety circuit is also tripped when the parking brake has not
been applied and the driver rises from the seat.
Drive to the blades is stopped when the safety circuit is
tripped. There is a short delay to prevent stopping if the driver
bounces on the seat.
When the safety circuit has stopped the drive to the
cutting unit, the control must be pushed and pulled out
again to start the blades. Drive to the blades can be
