Notes:  Maximum weight includes tractor and driver.  No over weight tolerances allowed.  Two tractors constitute a class.  If only one tractor enters a class, it will be the Superintendents decision as to which class the tractor will pull in.  A tractor pulling in a class of less than two entries, will not receive any points toward year-end awards for that class.  No exceptions.
