Bruce, we have a D20A6 with bolt on street pads. Very capable machine, and it will certainly out "bulldoze" any compact tractor or skidsteer. Have you used a D31P-20A yet? The D31 is about 16K pounds, all joystick operation. One joystick controls forward and back and turning, the other controls all blade functions. 6 cylinder engine, smooth as can be. A guy really needs both....of course it helps if you sell equipment for a living, you don't have to get permission from the better half when an "investment opportunity" comes up.
I think I'm taking us further off subject!
