Question on hooking up hydraulics

Recommended Posts


I'm trying to hook up the hydraulics on a loader. This isn't on one of my simplicity's but I figured someone familiar with hydraulics on here might be able to help as it likely pertains to any tractor. The loader has a double acting cylinder on the bucket but the loader cylinders are single acting. Someone gave me a new 2 spool control valve they bought but didn't use. It is a 3 position, 4 way valve. I'm not certain on how to hook the circuit up. The new valve has the inlet port on one side and the outlet on the other side. Beside the outlet port there is a steel plug, plugging a port which I figure is the power beyond port as the valve has this feature. Then there are the 4 work ports on top and they are marked A B C D. I'm guessing I would hook the hoses from the dual acting bucket cylinder to the A and B port. I'm not sure about the single acting loader cylinders. As this is a 4 way valve but the loader cylinders are single acting, would I run the hoses from the 2 cylinders to a tee and install them in the C port and then run a return line from the D port back to the tank? Or am I completely off on my assumptions?

Your best bet is to go to mytractorforum.com there is a section that deals with hydraulics. There is a gentleman or 2 that are very knowledgable that will respond early am. You want to get this right or you could blow your pump which is very expensive. I could chime in but I'll leave it to the experts. Be patient

Was back out at the tractor. Hooked the loader cylinder hoses to port A and ran a return hose from port B back to reservoir. Attached the hoses for the bucket cylinder to C and D ports and it works 100%.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
