By agreement of all affected
drivers this class my elect to pull at 8100 pounds or any other weight on which
they all can agree, for that pull only. Example:
If there are only two drivers and they both elect to only put on enough
weights to get to 8100 pounds, that will constitute the 8600 pound class for
that pull.
We
will also offer classes for Tractors 1961 to 1970, in the same weight classes as
above. All applicable rules will
still apply. At the discretion of
the pull superintendent these tractors may pull at the same time as the 1960 and
older tractors but points will be awarded for each class separately.
The
C-3300-L class is intended for 3300 pound tractors with PTO (or belt) HP rating
of less then 22 HP. The
C-3300-H class is for 3300 pound tractors with a PTO (or belt) HP
rating greater than 22 HP.
At the discretion of the pull superintendent these classes may pull at
the same time but points will be awarded for each class separately.
Tire
and wheel sizes listed above are only meant as a guideline.
Each tractor can only pull on one tire size larger than that tractor was
originally available on. NOTE:
Tractors that were originally on steel and are now on “cut-offs” are
allowed to go by the tire sizes that were on that series of tractor, when rubber
tires were made available.
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
towards the Grand Master Puller. However,
Class Master Puller points will be awarded for each tractor entered..
