Here are some pictures of a 4WD Cub I made a couple years ago. The wheels swing under the seat and fender pan so I could put a cab on it for blowing snow. I used old car wheel bearings to make the frame connection so it rotated and pivots. Been using it for several years to clear snow with no problems. It has Case differentials under each end with hydraulic motors on each with high and low range. Hope this helps.

Redneck, that's very cool. Hydraulic motors simplifies getting power to the axles.

Used a window regulator to rotate the shoot from inside the cab. I will try figure out how to attach an action video.

I like the way Cubzilla has the front axle "up front" as opposed to behind the engine, with the engine overhanging the front axle as so many articulators are done.
If using Cub axles, why couldn't you use the front PTO and a belt to drive the input to a cub hydro, mounted in front of the engine, driving the rear shaft at the back of the hydro, or under the engine, driving the normal input point. That way, you could engage or disengage the front axle via the PTO. You wouldn't have the same power (due to belt drive) but might be another way to do it. You still have to deal with the universal or CV joint at the articulation point, or, as Cubzilla has done, use a hydraulic pump and motor. Using the front PTO for the front wheel drive precludes any other PTO uses. The pair of axle hubs for articulation is interesting.

Upload to youtube or another hosting site and post a link. No way to post a video directly to the forum. I see you don't even need chains! That's a bonus. Neat tractor! Tell us more about the hydraulic pump and motors you used. How did you mount the pump? Pics of you have them.

The first year I had ag tires on the tractor. On frozen ground they didn't work as well as turf tread. I've run it through some pretty deep snow with no issues.
Regarding the hydraulics, as I recall it is an 8-12 gallon per minute pump, the reservoir is 3 or 4 gallons (from Northern Tool). Made a bracket to hold the pump and attached the pump to the flywheel with a rubber type coupler. The oil comes out of the pump into a priority valve, prioritizing the steering then to the hydraulic motors on the transmissions. The motors are plumbed in series for full time 4WD. The hydraulic cooler is under the seat with 2 DC fans from inside a computer for air movement. There was concern that the reservoir was too small and the oil would over heat, but that has not been an issue. The pump is tucked behind the engine and under the fuel tank so it will be difficult to photograph right now. I can get additional details on the coupler between the pump and the flywheel tomorrow if anyone is interested. Any portion anyone would like a close up picture of, let me know and I will do my best to share. I will try to get one of my kids help with a video. I appreciate the interest in this. It took about 2 years, on and off, to build. My neighbor is a wizardly smart mechanical engineer and we spent may hours thinking this through, building, tearing apart and re-building. I just wanted to acknowledge his very significant contribution.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
