David USMC,
I have the TC18 HST and feel these tractors are very durable! I've worked mine in moving fill dirt, top soil, and cutting sod/topsoil with the rear scoop and no problem.
Supersteer, don't know much about, someone posted that it would probably be nice it you had to get into and around stalls...I'd agree. My TC turns around just fine at the end of mowing rows with no brakes. Don't know what type of injection the engines are?
Here's an excerpt from the Shibaura webpage:

My TC18 has a serial # plate on the front bumper that reads "Made in Japan" so I believe that my whole tractor was made in a Shibaura factory. However, there is a new plant in Dublin, Georgia for production/final assembly?
Good Luck, JimBinMI
