my guess is your not going to find one, It does not look like they ever made a factory option even, and unless there was a transfer case transmission made for it I would think to add a mechanical 4x4 is not a realistic reality,
small possibly one could do a hydraulic driven front axel, some what like Deere did for the 4020, but they had a larger pump and some additional hydraulics to make it work, and I do not know if it was set up to work in one or two gear ranges or what, and it was called an assist not 4 wheel drive,
Form what I can tell they had kinda two speed system on the drive, one was to split the flow to each motor on the wheels and the second circuit was to go to one motor and then to the second, (series and parallel circuits) how the flow was regulated to match the mechanical I do not know, then you have the forward and reverse shifting as well, I guess I could see a series of valves to select the gear match up with flow control on each one, but unless one was clever I would thin to shift would be like having to shift two transmissions at once, and even the forward and reverse could get tricky,
(edit) possibly micro switches and electric valves,? the other idea that came to me a hydraulic motor drive off the rear axel of the tractor and basically a closed circuit to the motor/s, on the front axels , (not sure how one could cool it, if you have so the motor would pump in reverse for reverse, unless some check valves for one could use a reservoir tank or a cooler) but a closed hydraulic system drive off the rear axels could possibly be used to drive the front axel in the same speed as the rear),
(second edit) if one could chain drive a small differential off the rear wheels and then put a short drive line to the front 4x4 axel it could possibly drive it, (my guess is one would use a 4x4 axel out of a pick up, and by the chain drive and the differential gearing I would think one could get close to the proper ratios, and it would be self contained no extra to kick it in or match gear ratio.

my guess traction is your desire,
back in the 50 and 60 there were a lot of inventers that were trying kits and ideas, just to do that duels were probly the easiest solution,
but some "half track" kits were made and built,
also some made a kit to tie two tractors together in an early articulated 4x4 unit,
I am sure neither is what your looking for but it is most likely a more doable option than a "4x4".
you may find this of interest, Patent US5361860 - Conversion unit for wheel-driven tractors - Google Patents
apparently steering is by a hydraulic cylinder attached to the pulled implement.

The Polish do a lot of conversions on the Ursus C-355 and C-360 tractors: They use a dropbox of a later Zetor 4wd because these Ursus tractors are based on the Zetor 4011. It seems they shorten a 4wd axle with offcenter differential of a light army truck, and narrow it to a center drive 4wd axle. You see quite a few of these conversions, though the factory never sold 4wd on these...
This seems to be an axle of a Russian ZIL truck

And this a Landrover front axle... wonder how long it stays apiece though ?? Not suitable for frontloader action :/
