I am actually reviewing a Shibaura SD 1500 AO. It was my first compact utility tractor. I bought it for $2500. It was a true gray market tractor with rice tires, no guards, and Japanese writing. It was a 2 cylinder diesel so it kind of stuttered when it ran but it sipped the fuel. It had 4 wheel drive. It had 15 hp PTO but performed like it had 20.
I mowed 8' tall brush with a 4' brush hog. I did a lot of work with that tractor, but sold it to buy a John Deere 850. My only complaint was that it was petty narrow, so you had to be careful on side hills. I was able to get routine items like filters at NAPA.
Many Ford parts are probably interchangeable. I really liked that tractor.
