These are Turkish made and are widely used through the fruit orchards, vinyards, and olive groves of Western Turkey. Some models equipped with a rear PTO run a shaft to a repurposed auto transmission to drive a rear end. Some of those units will make 35 mph downhill!
Some have pinned wheels that can be replaced by more conventional tines to convert to a rototiller to work the small plot before converting back at the end of the day to the owner's house in the village.
The two wheeled tractor may not be all that common in North America, but there are lots of dealers in western Turkey.
