this all worked for me, and i need to tell everyone. 6 months ago we bought a fully hydraulic loader to fit our d17. then the hard part. we got a pump and reseivor off a gleaner f at a salvage yard, custom made everything to mount and drive the pump. mounted the tank on the loader frame,then came the valves. northern hydraulic has a joystick valve that we mounted on a homemade bracket. i even plumbed another valve so i have live 2-way outlets on the back. finally got it all put together today and it all worked just like the plan. using salvage parts, new valves and hoses total cost was less than $800.
