!CAUTION!

If you are going to use a closed center tractor hydraulic system to power your Land Pride Backhoe, A Power Beyond and Closed Center Kit must be purchased from your Land Pride Dealer, then you must carefully follow the directions below.

Refer to Figure 1-2:

1.Adjust Valve Bypass for Closed Center Conversion only (Kit #340-084A).

b.Loosen locknut and turn socket head screw in approximately four complete turns, then tighten locknut.

c.Replace cover nut. Be sure to replace the washer along with the cover nut as it acts as a gasket.

2.Installing the Closed Center Sleeve.

a.Return hose must be connected to the return section of the valve at point “A” and with the other end to the tractor.

b.Remove plug at point “B” and install the closed center sleeve (#1). Use the plug (#2) that was removed to plug the sleeve.
