Using our 856 every day. Yesterday my son started the tractor to haul manure, and no hydraulics. The 3 point is up and will not lower, and feels spongy in the raised position. Also there are no auxiliary hydraulics. There is nothing. Drained the rear end, pulled the hitch pump,and checked it and it seems fine. No chewed up pump gears, drive gears, or blown seals. Hydraulic pump flows a lot of oil when spun by an electric drill immersed in a pail of oil. Hydraulic pump drive gear is fine and the PTO works good. I figured the next step would be the relief valve, but why doesn"t the 3 point lower?
