1. A Warning The presence of air in the hydrau lic circuits will cause the implement to oper ate erratically and is potentially very dan gerous when folding wings or transporting the implement Depth Control The depth control circuit consists of master slave cylinders in series Generally the depth control system will be factory primed If not refer Hydraulics Sys tems section of this manual Wing Fold A hydraulic circuit is employed to fold the wings from the working position for transport or storage This circuit is inde pendent of the depth control circuit The wing fold circuit consists of a number of non phasing double acting cylinders con nected in parallel A Generally the wing fold system will be facto ry primed If not refer Hydraulics Systems section of this manual Connector Bars The connector bars linking the rear wheel assemblies to the front cas tor wheels are factory set to a nominal length The length of the connector bars may require adjustment in order to level the implement front to rear on each wheel set To adjust length use the large spanner sup plied to release lock nut at the rear and ro tate the central shaft Do an initial level check while machine is resting on the transport stands when lifting off the stands the front and back wheels should touch the ground simultaneously For more infor mation refer Field Operation Frame Ad justments section of this manual

17. Circuit The depth control circuit found on the im plement consists of a master slave rephas ing cylinder system connected in series The master slave system means that the rod end of the largest master cylinder is con nected to the base of the first slave cylinder and then the rod of the first slave cylinder is connected to the base of the second slave cylinder The sizes of the cylinders and rods are matched such that a certain extension of the larger cylinder will displace a volume of fluid from the rod end which will match the volume required by the next cylinder at its base end to extend the same distance These rephasing cylinders have a valve with in the piston that allows oil to pass through the piston when it is fully extended or re tracted The benefits of this feature are twofold i e the cylinders are able to re synchronize re phase compensating for any leakage in ternal or external and at the same time purge air from the cylinders and hoses back to the tractor Note With these rephasing cylinders it is NOT necessary to remove hoses or fittings to achieve bleeding of the depth control cir cuits 1295 s dyd Single fold Depth control Circuit Priming the Depth Control Circuit Note Ensure the tractor s hydraulic flow rate to the implement is between 60 and 120I min
