Hydraulic Hose Connections
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If injured,
seek immediate medical assistance from a doctor that is
familiar with this type of injury.
Connect the hose coming from the flow-control valve (1)
on the seeder to the pressurized side of the remote
circuit.
Connect return line to sump (2).
Check that the seed-cup shaft on the seeder is rotating in
the correct direction. When standing on the left-hand side
of seeder, the shaft should rotate counterclockwise. If
necessary, switch hoses at outlets.

NOTE: For tractors with open center hydraulic
systems, refer to your tractor manufacturer’s
recommendation before connecting the hydraulics on
this unit.
For future reference, refer to the plastic hose holder to
distinguish hoses.
