Scott my older brother had a few of these tracked dumps in his dirt moving businesses, I think Morooka was bought by Mitsubishi, or IHI. We had a small Morooka and Yanmar the Yanmar had tires though 8 wheel drive with 2 steering clutches. THe run thing about it was it was a direct drive power shifft and had a 3 speed transmission perside. Fun to put it in revers on one side and 3rd on the other. We used them in tight spots for dumping gravel or hauling spoil out of steep slopes to save trucks. I liked the Morooka because the seat swiveled to a set of rear controls when backing into a narrow alley or a tight hill.
