Locate shield forward/back and up/ down to provide the best overall coverage for the tractor operator. Use a spirit level to level the shield before marking. Mark frame location with a pencil on each side of the ROPS bar; and mark vertical ROPS location on the shield frame. 4. Position protective shield (#5) on a flat work surface. Locate one of the flatbars (#4) next to the pencil marks to determine which set of holes will clear the vertical marks for the ROPS location. Mark hole location and drill two 1/4" diameter holes through the shield frame. Similarly mark and drill two additional holes for the lower clamp location. 5. Attach shield to the inside surface of the ROPS bar with 1/4" x 4" cap screw (#6), 1/4" flat washer (#3), 1/4" lockwasher (#2), and 1/4" nut (#6). NOTE: To determine the best location for the protective shield, the cutter should be connected to the tractor, parallel arms should be fully extended and the deck should be approximately horizontally level.

CAUTION The breakaway cylinder is designed to bypass hydraulic fluid under high pressure when cutter head or parallel arms strike an object during forward movement. Do not use a standard hydraulic cylinder for the breakaway cylinder or damage could occur to the unit. The breakaway cylinder is used to prevent structural damage to the cutter head and parallel arms. If cutter head strikes an object during forward movement, the breakaway cylinder extends - allowing the parallel arms and cutter deck to freely pivot 90 degrees to the rear. The breakaway cylinder should be installed as shown in Figure 6-2. Make sure the rod end of the cylinder is mounted to the pivot lug as shown. Connect both hoses from cylinder to a remote duplex outlet on the tractor. Pressure Shut Down Valve Operation Refer to Figure 6-2: Standard pressure shut down valves inherently leaks a small amount of oil allowing the deck to drift back during field operation. When needed, reset cutter deck forward using tractor control levers. Optional pressure shut down valves are available that will greatly reduces the frequency of deck drift but they will require continuous force against the deck to move it back. Deck does not pivot back as freely as it does when using standard pressure shut down valves. See Land Pride’s Parts Manual No. 316-111P for ordering either the standard or optional pressure shut down valves. Order only genuine Land Parts from your local Land Pride Dealer. IMPORTANT: A 1/2" bolt is installed for shipping purposes only. This bolt must be remove before connecting the hydraulic hoses to the tractor. Section 6: Hydraulic Plumbing Remote Cylinder Plumbing For Tractor Control Figure 6-1 27974 Breakaway Cylinder Installation Figure 6-2 Tractor Control Refer to Figure 6-1: “ARM 1”, “ARM 2”, and “Deck Pivot” cylinders are connected directly to the tractor's remote duplex outlets as shown and are controlled by the tractor operator. See “Tractor Control” on page 19 for assembly and set-up instructions. See Figure 6-6 on page 39 for hydraulic plumbing of the deck motor. 24633 Important: Locate and Remove 1/2" Shipping Bolt Before Connecting Hydraulic Hoses. 38 Section 6: Hydraulic Plumbing RCP2660, RCPM2660, RCP3060 and RCPM3060 Parallel Arm Rotary Cutter 316-111M 10/11/12 Table of Contents Solenoid Control Refer to “Solenoid Control” on page 19 for assembly and set-up instructions. Solenoid Plumbing The flow control valve diverts excess oil back to the tractor. It is important to know the tractor’s rated GPM flow (15 GPM & under or 16 GPM and above) and to plumb the flow control valve accordingly. For a detailed description of plumbing, see Flow Control Valve Plumbing on page 21. Float Control Valve (15 GPM & Under) Refer to Figure 6-3: This arrangement requires a check valve between the tee and return line. Make certain the check valve is plumbed correctly so that oil can flow towards the tee fitting in the direction shown by the arrow. Make sure the lines connected between the tractor and flow control valve are set-up to flow oil in the direction shown by the arrows. Float Control Valve (16 GPM & Above) Refer to Figure 6-4: This arrangement requires a return to tractor sump line. Make certain all three lines connected to the tractor flow oil in the direction shown by the arrows. Hydraulic Cylinder Plumbing Refer to Figure 6-5: Make sure “ARM 1”, “ARM 2”, and “Deck Pivot” cylinders are plumbed to ports (SA, SB, SC, SD, SE, and SF) at the solenoid control box as shown.
