What acreage range are you aiming this machine towards?

Direct current electric motors would work well because they can be slowed down easily, but that would require a direct current generator, and I could not find any the size I would need.

It would be a way to use off the shelf parts that would get a system running, and potentially lead to so custom produced parts if needed.

Converting 1 to 3-phase needs, IIRC, a 3-phase motor which is powered by the 1-phase and puts out 3-phase. Roughly speaking. Been 10 years since I considered adding 3-phase to my shop and I never got around to it; the details have gone and slipped. I think I was looking a 10hp motor for the converter to run 3-5hp 3-phase in the shop. Not pocket sized but maybe you'e dealing with a chassis large enough to take it in stride. Again, IIRC, you get 70% () efficiency out of it. There's a connection between the size of the motors and the efficiency. I think I recall the going bigger was more efficient. There's lots of good info out there on the calculations and the practicalities for a home brew. If you want to get into that. Must be commercial offerings, but I don't know what the price on those might be. Maybe in the end be better to get a 3-phase genset. The info is out there but there's lots of electrical magic needed as well as mechanical fabrication.
