o.k. so everyone's familiar with a good old bulldozer, but what if it's not a massive machine but nevertheless has a hydraulic blade at the front. Maybe a dredger (on water?) or an excavator?
Where does the front-end loader come into this? Or a (mechanical) digger?
What about those ones with the scoop at the back?
In Australia I've heard those really little ones dubbed Cats or Bob-Cats too.
What would each of you say? Though more importantly, which terms are understood by English speakers world-wide?
