4420 combine with 4wd question

My brother went to look at a 4420 combine with 4wd today. I didn't think that combination was possible. I thought that the only a hydro machine could have a 4wd axle.

Is that a factory option or aftermarket?

What drives the rear axle and controls the speed?

Anybody have experience with one these?

Since its rained just about every day since labor day here in PA, 4wd might be nice to have. lol
 
I was harvesting in the mid 80 with a 4400. One bad fall when we were trying tracks and other things to get the crop harvested I heard of a man here in Southern Illinois who was fitting the front drive axle of a military vehicle to the rear of the 4400. The way I remember it he was drilling through the transmision case and installing a drive shaft to run to the rear axle.I do not know how successful these were or how many he made. I only heard about it one time.
 
I know of a fellow that put some type of truck axle under the rear of an old case combine along with a second engine and transmission to push. Never saw it for myself(was still in diapers), but was told it would throw rooster tails from one end of the field to the other. The push axle was turning more than a little faster than the front drive tires. He got his crop and then a little custom harvesting that wet fall. I'm only in my thirties but have way more experience with mud, combines, tow boat ropes, and very long cables than someone my age should have. Learned a valuable lesson a few years ago. We modified the combine with piggy back hydro coolers, 67x34x30 tires with the huge forresty lugs like on skidders, and mudhog ofcourse. That's just enough to get you far enough out there that nothing can get to you. Couldn't run with much more than 100bu in the grain tank. We were running the grain cart on the 8440 and it was only able to pull a bushel per engine hp. the only place to could build up a little steam was where the water was over the pto shaft. It was a miserable experience, but we got that bottom harvested. Got hung on the ridge above the bottom, and was hung for 7hrs. That's the day I aquired a 100ft 1 inch cable. Also had to bring in a dozer to push mud down to find hard dirt so the 8440 could get a bite. That has been five years ago and that spot has never recovered. Sorry, I got started rambling about combine mods and mud, but talk of rwa units on harvesters gets me thinking about those good old days.
 
I have heard of them but do not know for sure who made them. They apparently had their own heavy hydraulic pump to drive them. I'm guessing they had a flow control valve of some kind to control the speed. A few were sold in this area. Mike
 
I have a 4400 4x4 with rice and cane tires up front and about like new long bar thread tire in the back, with the mud hog on. Let me tell you, that thing will go through a lot.
 
That'd be a great idea if we lived far enough north that we could count on a freeze to last long enough to hold equipment up. You'd have to know the land and then make the decision to wait or dive into the mud and get it.
 

I just purchased a 4420 with Powered Rear Wheel Drive. I think it is probably the only one out there. Plus it only has 2800 hours on it.
