I've got a '76 John Deere 4430 powershift. It seems as if the hydraulic system shut down. I currently have no power steering and the hydraulic remotes don't work. We've tested the hydraulic pump and it is pumping oil. It appears as if the hydraulic oil is being dumped somewhere in the system and is not making it's way to the power steering system and hydraulic remotes. Also, the tractor shifts hard from 7th gear to 8th gear. I wonder if the problem might be a stuck valve somewhere in the system or if I might be looking at a much bigger problem to contend with. i.e. transmission or having to split the tractor. Does this sound like a simple repair or a major repair. Any insight would be most appreciative, Thank you. Jack
