7.4 Hydraulic Plumbing – Option 1
Hydraulic Plumbing - Option 1 requires the optional switch box for manual control of the
Linear Roll functions.
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the valves are mounted on the sprayer, the hydraulic hoses and fittings can be
installed (plumbed).
2. Install tee fittings on the TR and TL port fittings at the HARDI block.
3. Connect pressure and tank lines to the HARDI block (P1 & T1). Connect the other end of
the hoses to the NORAC block.
4. Connect the “B” line hoses to TL1 and TR1 port fittings at the HARDI block. Connect the
other end of the hoses to the NORAC block.
5. The “A” ports on the NORAC block are plugged.
6. Install Rexroth one-way restrictors (GSU2.38.100; HARDI part number 78211900) onto the
left tilt (TL) and right tilt (RT) lines as shown in Figure 23. The restrictor should be
oriented with the free flow towards the tilt cylinder and control flow towards the HARDI
manifold.
