About Micro-Mini Tractor Pulling

Micro-Mini Tractor Pulling is a 1/16 scale version of full size tractor pulling.
A weight transfer sled is pulled by these small "toy" pullers on a 2'x16' wooden track which is
either covered with a formica surface or sealed with a smooth surface of polyurethane. Some of
these pulling units in the 6 lb. open modified tractor class have been known to pull in excess of 600 lbs.
