Traveling/Working Circuit
Set the traveling/working changeover switch to
the "Working" position, and then shift the
mower unit up/down lever to the "UP" position
Thanks to the functions of the proximity
sensors and electro-magnetic check valves,
the mower units #4 and #5 stop at the working
positions.
