When removing pipes from the tractor make sure all hydraulics are fully open or fully closed before
applying float on the tractor.
The wings are fitted with check valves on the rams which allows them to be depressurised without
letting the wings unfold.
The changeover tap for the wings and bout markers (4m, 4.8m and 6m versions only) is located on the
front of the chassis beneath the hopper access steps.
FREE-FLOW RETURN
Damage will occur
to either the fan motor seal or the oil cooler (oil coolers are only fitted to seed &
fertilizer machines) if the free-flow return hydraulic line is not connected to the tractor first .
Any movement of the fan or the coulters immediately pressurizes the free-flow return line. This includes
just lowering the machine to the floor to allow the coulters to “take some weight”. Doing this will
displace oil from the coulter rams and pressurize the free-flow line, which may result in component
damage.
When connecting the free-flow line it is necessary to observe the back pressure present. A gauge for this
reason is provided, mounted on the fan. The maximum return pressure is 15bar. Running with a pressure
higher than this will result in damage so it is then necessary to take steps to reduce the restrictions in the
free-flow line, usually at the point where it enters the tractor.
