I have a L2600 series tractor with a front end loader. I am trying to hook up a post driver. I have t'd the hydraulic line into the block for my line to raise the driver and run the outlet hose on the driver outlet to go back into the cavity of the tractor. The problem is that the only thing that moves when I use the driver is the 3 point hitch. Do I need to buy a another device to run the driver separately? Any help would be appreciated.
