HYDRAULIC VALVE
There are two adjustable settings on the valve
• Floor speed control
• Floor pressure relief setting
Floor speed control
(See illustration No III)
The floor should not be moving when the indicator is against the slow stop. To adjust, undo the
bolt on the clamp and turn the control lever till the floor stops moving.
Floor pressure setting
This is the adjustable cartridge on the bottom of the valve. This valve will divert the oil from going
to the floor motor, it will instead go back to the tractor. The oil is diverted when the floor is
getting overloaded and will go back to the floor motor once the elevator has cleared the load
against it. To get more pressure to the floor, undo the locking nut on the valve, then screw the
knob clockwise ½ a turn at a time, then run the wagon to check if this is the correct setting for
your tractor and loading. To get less pressure to the floor, turn the knob anti clockwise.
You may need to screw the valve in:
• The first time you use the wagon and the load does not come forward.
• If you travel further and get more compacting.
• If you load the wagon at night and it rains. This will make the load heavier.
• If you change pits and the second pit has heavier silage.
If you screw the valve right in and leave it there, you will have very little protection on the floor.
If you then have a jam there is a good chance, you will do damage to the machine.
The motors and valve on the wagon are sized and set to meet the size load the wagon can carry
with the average tractor oil flow and pressure that could be pulling the wagon. With smaller
wagons, you can get away with a tractor that may not be up to specifications with flows and
pressure, but when you get up to the larger wagons, if the tractor has not got the performance or
not working to its specifications, then the wagon may not feed out as expected.
