I have a friend that had his JD 4430 throw a rod. Broke the block. The trouble is the tractor is about one mile back into a hilly pasture. I need to get it pulled out to the road to haul it. There are some 8-10% slopes that we will have to go up and down.
So I want to supply the steering and brakes from the tow tractor. The supply is easy. The line comes off the high pressure line on the right side an goes straight up to the hydraulic dampener and then on to the steering/brakes. The return side has me a little stumped. The steering metering valve has a small rubber line that comes down to just above the clutch valve for its return IRC. Where does the brake valve return too??? Do I even have to worry about it??? IF the brakes are kept slightly depressed to hold back while it is being pulled will there be any return oil form the brake valve??? I think there would only be a small flow just when the brakes are released. Once the pressure on the brake pistons is dumped there would not be any oil flowing. So if this is true than what little oil would be returned would just add to the JD 4430 sump level. The tow tractor would loose some but it would not be enough to worry about just from the brakes.
Am I remembering this correctly??? Do any of you have an easier way???
