Hi,
I would like to hook up a hydraulic motor in the existing hydraulic system that which is used to raise the trailer unit, is it possible? if yes then how to do? If not,then how to hook pto pump and a motor on the other rotating equipment in the tractor.
Thanks

If I am reading this right, you want to run two circuits off of one set of hydraulic aux lines. First you still want to raise the trailer. And second, you want to run a hydraulic motor.

Yes, you can do this. The simplest way is to install a manually operated diverter valve. This has the advantage of no modifications to your tractor.

The next best way is to install a 12v solenoid operated diverter valve. You can get power from either the cab or 7-pin connector behind the cab. Be sure to use a fuse. The 7-pin connector is attractive because you could rig a small box with a cord that runs through the back window, and would be easily transferred to other tractors. The circuit that runs without electrical power should either be the one that runs most, is the most critical and can't afford a power glitch to stop, or needs to work with other tractors that don't have a switch installed.

If the motor can only run in one direction you can install a one-way valve to short the motor if the aux lever is pushed the wrong way. (commonly done on rotating broom and pavement grinding attachments) If the motor needs a tank/vent line make sure to vent that separately and don't use the "return" line, as inadvertently applying system pressure could blow the shaft seal out. Cold oil could also create enough pressure to blow a seal out.

Thanks Zebra,
We will not use the trailer when the motor in use or will not use motor when trailer in use and the trailer has an single acting cylinder.
