That little Kobelco dug good, it felt like a regular excavator just smaller. We had to dig in three window wells, two were in the back with restricted access and we dug down almost five feet I think. It was around 3,000 pounds so easy to haul. If you had different buckets it could be very handy in compact work and lets be honest it sure beats shoveling.
I like my TK so far and would think the smaller ones would be good as well. The Case/Kobelco minis I think are also very good.
Do or do not. There is no try. yoda
