We have a Baoli.  Chinese built but with the common drivetrain, Mitsubishi/Nissan or whatever engine is common.  Been pretty trouble free other than a cylinder rebuild and an episode of rat damage.  Not many days that it isn't used for something.  Has worn out pneumatic tires so soft ground, even gravel will stop it.  Saw some conversion kits for a skid steer tire at Louisville but they were $2000+ IIRC.
