Help on JD 4430!!! Exteranl hydraulic supply??

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???
 
I would take 2 tractors of equal size chain one to the front,chain the other to the back longest chains you can get,put tractor in tow one in front pulls and tractor in back is just there for brakes both tractors same gear.We retrieved a big Massey this spring this way off a big hill
 
I think I would use a solid pole from one tractor drawbar to another, and tow the 4430 backwards. As long as there is steering, I think you would be OK ,but I don't know the hills you are dealing with.

Good luck and be safe.
 
Several things to know. The biggest is the JD 4430 tractor has full hydrostatic steering. So without hydraulics you have a few turns of the steering wheel and your done steering. I am not worried about braking in that I know you can use two tractors to tow and stop the towed tractor. I need steering because part of the farm trail/road is 12 foot wide with a 20 foot drop off down a limestone bluff.

Then the steering and brakes are fed off the same supply line. So If I do not get both to return to the tractor supplying the hydraulic pressure it will slowly add oil to the JD 4430 hydraulics stealing oil form the other tractor.

I may just build a lift for one of the big tractors and just carry the entire front end. I made one years ago for my JD 5020. A heavy cross link for the lift arms with a heavy square tube hooked to the top link mount then back across the cross link. So when you raised the three point hitch you raise the end of the tube/boom.

I am also going to measure how wide the tires are to the outside. My brother's end loader has an 100 inch bucket on it. We have moved smaller tractors by just scooping the rear tires into the bucket and then chaining the tractor so it can't roll out of the bucket. Then just let the front end roll along while carrying the rear end half. For you AC buffs it is a 945 Fiat Allis loader. About a 7 yard machine. I wish he had forks for it and then it would be easy.
 
Disconnect the lines to the "steering motor" and connect it up to some long hoses plugged into a pair of hydraulic remote ports on the tow tractor and steer it with associated SCV lever. I have done that several times with tractors and combines, the last being an 8820 which we'd removed the engine from at the shop and needed to move it to the "boneyard" area. A little awkward, but simple and effective.

As others have said, it can be "held back" by another tractor.
 
Yes, how long the steering "lasts" towing those is always interesting. Some you can steer a long time, some it seems the hydraulics bleed off and you are left with nothing after one turn!
 
I just backed my 4440 up to my dead 4240,hooked a chain around the front axle to
my quick hitch,picked it up and drove home.
 
Tow bar. Bolt it directly to the front axle and pull with a tractor at least as heavy as the 4450. Gives you braking action and direction control. Ben

A 4440 was a bit much for my loader, but I bet that 945 would make short order of the job.

Use the big loader and scoop the front end up. We do this with the loaders to move the 2 cylinder around. Strap the front into the bucket for safety and away you go. Good luck
 
We use to hook a chain over the top of the center of a quick hitch,then cross them and go down under the front weights,place a 8X8" block of wood between the chain and the front weights, raise the front of the tractor up to get the wheels off the ground, then ran another chain from the draw bar of the tow tractor to the front end of the dead one, being careful not to turn too tight..and above all make sure the transmission stays in Tow..have some one in there making sure...This works well...
 
Or borrow a trailer from some one, drag the dead tractor
Onto the trailer and tow the trailer with a farm tractor. Have a customer that's how he moves his escavator, low boy pulled by a 3690 mf with dual wheels.
