4 WD using Case Transmissions

I made this using Case transmissions along with a lot of advice from people on the site. I have a Cub Cadet stable so I used a CC frame that will connect to my snow blower. The most unique part is the articulation joint which is made using two wheel bearings from the front of a car attached to a cut down beam. Now on to putting on the sheet metal and building a cab.

RENeal - So far your 4 WD looks pretty cool. It'll be great to see it when it's complete. I'll agree with lil ol 220 - "Where's the oil cooler?" Seems to me your seat is somewhat high for the steering wheel but that could just be your mock up setting - either way it's lookin' pretty cool thus far. We won't all the pictures you can give us when you can!!!

I removed the battery from under the seat and built a holder under the rear fender for the battery. That opened the area under the seat for the oil cooler and two computer fans for cooling.

I did have the seat blocked up in the original pics, but the steering wheel is still a little low. I am open for any suggestions on how to extend the splined shaft on the orbital valve to raise the steering wheel.

I will try to attach a photo of the oil cooler and the articulation joint:

I have been thinking about this tractor and some others I have seen like it.

I have a question about the design.

Do any of these tractors have universal articulation, XY axis movement? My concern is that the frame could VERY easily twist if one end of the tractor were to be lower or higher such as one wheel in a rut or going over a large rock.

I don't see any suspension to speak of and I really am wondering how this is not a problem on these tractors. How does it cope with changes in terrain without a pivoting axle or a frame rotational bearing? Does this tractor have something like this already?
Anyone?

You are not wrong. He stated early on that he used a pair of car front-wheel hubs to make his articulation joint and then provided close-ups of it. Certain people who shall go nameless need to focus on that which has been written before asking questions. :biglaugh::biglaugh::biglaugh::banghead3:banghead3

Well I HAD read that before, but he didn't really go into detail on how he used them and the angle of the picture to me lookes like the rotaion is fixed solid with the bolts oriented the way they are.

I can see the side to side pivot point, but the rotation looks bolted solid. Perhaps some better angles of picture instead of the duplicate rear shot would have helped.

Also in the picture, it doesn't look like the fram tabs would clear if there was significant twist in the frame.

Either way it doen't matter becaue this is not a project I would ever try or have a need for.

Really just trying to pad my post count.

But I would be curious to hear what the OP has to say about it.

The tractor does both pivot and rotate. I took a piece of 6" beam and cut one leg off it to creat a side ways T. Used the part cut off as bracing to keep the joint from flexing. Put one bearing hub on the verticle part for the rotation and another on the flat part to let the tractor pivot.

The joint is welded to the botton of the frame which lowers the center of gravity a little and also keeps the inside of the frame clear to run hydraulic hoses and what ever else needs to go through there. Had to trim the frame a little to clear the tires if it rotated while in a turn.

Came up with the design after a lot of sitting, looking, and thinking with my neighbor, Mike. Mike is a great guy to think with.

Used old bearing hubs from a garage that had changed them out of a car and was going to scrap them.

Might be some issues that arise as the tractor is put into service blowing snow, but those will be adressed at that time.

Any thoughts about how to take the warm air from infront of the motor and channel it back inside the cab for heat? I understand one has to be careful about exhaust fumes, but any idea how to get the warm air re-routed? I have not built the cab yet so now is a good time to consider creature conforts.

People on this forum have been great with ideas, suggestions and explaining hydraulics to me. I'm sure I will be asking for advice again on the next project. Now back to building the submarine............:thanku:
