Neat tractor, but WAY overpriced as far as I am concerned.

Nice build. I often wonder how much they sink into a build like this.

The Case drive system solves all the 4x4 problems I've read about. Plus you can use the lift side of the valve for the steering with dual cylinders. I've really considered throwing one together.

If he just plumbed up the hydraulic drives in a series it is NOT true 4wd. I've tried this and it is not true 4wd. But it's WAY cool looking FOR SURE!! I love the look of those old Case machines too. Just hate that old school hydraulic drive, this is probably why I haven't picked one up yet. But I will one of these days ....

So all his builds have the hydrive system?  I never cared for that system.  Not knocking it, but just not for me.

Keith, please explain why it's not true 4WD.  Inquiring minds wanna know.  Not knowing your explanation, would using a flow divider which truly splits the flow equally between 2 circuits make it true 4WD?

Keith, please epressure hy it's not true 4WD. Inquiring minds wanna know. Nor knowing your explanation, would using a flow divider which truly splits the flow equally between 2 circuits make it true 4WD?

Yes Dan, but it needs to be a rotary style to truely divide the flow. Under pressure, with out the divider there is no way it can provide enough pressure or volume to effectively run the second motor. And if you stall the first one the relief kicks in and diverts pressure to tank.... Game over.
Just remember you cant get something for nothing!!!!! ESPECIALLY WITH HYDRAULICS!
Now if you use the rotary divider you will cut volume in half so you will only have half speed at load. Thus you need more volume, with the added volume is the need for added hp. Then you need more capacity and cooling too.
And the thought of the oil bypassing the stalled motor to feed the second one.... Lol yeah cc's maybe.
Then what do you do with all the added volume for say a tiller or loader?

If you used a bouble section 16gpm pump and had dual drive valves it would only require a few more ponies, as the normal 2wd will do most of the work anyways, its only when you need the extra traction thatyou would need the extra volume.
Duel hydrosstat trannys are much more efficient.

As I'm going through this in my head I though of another easy method that would work , but it would need a bit more pump volume. Flow divider with an additional direction valve. This keeps each motor pulling when things get tough and only rob a tiny bit of power .
But any way you slice it you need to separate the flow.
One other tidbit case pressure can blow out seals on the motor that has created high pressures on its return side. Some don't like this at all, while others will tolerate it.
