Yair . . . our SBS television news service showed a couple of seconds of what appeared to be a six wheel skid-steer pushing snow at the Superbowl Stadium I am aware that (I think) Melroe made such a machine in the past but didn't realise such machines were still around. Does any one know what it was or care to comment? Cheers.
I didn't see it personally but maybe what you saw was a 6X4 Deere Gator: http://www.youtube.com/watch?v=qERMZvU11I4 or this: http://www.youtube.com/watch?v=_DmFql9EE_8 Bobcat six wheeler: http://www.youtube.com/watch?v=xaquec4yI9Q
