One of the most popular tractor classes in the eastern United States is the combined division for Limited Pro Stock and Super Farm Tractors. This group of tractors closely resembles the normal Pro Stock Tractors. The primary difference is that the Limited Pro Stock class is ‘limited' to a 540 cubic inch engine and is required to use a much smaller fuel pump for competition.   The Super Farm Tractors may run up to 640 cubic inches but that class is limited to a much smaller turbo-charger.

The other noticeable difference with this class when compared to their ‘big brothers’ in pulling is the great variety of manufacturers and thus a great diversity of ‘color' in the class. Ford, New Holland, International, Case, John Deere, Oliver and Duetz are all seen in this class.  The division is sanctioned through USA-EAST Sled Pulling, Inc.

The Limited Pro Stock/Super Farm class is sometimes seen along with the Interstate Pullers Association but is called ‘Mod Turbo' in the eastern part of Pennsylvania as well as Virginia and Maryland . The rules for the Limited Pro Stock division and those of the Interstate Pullers are quite similar allowing tractors to move back and forth between the two divisions. The annual pull at the Bedford County Fair in Bedford, Pennsylvania is an opportunity for both the USA-EAST and Interstate pullers compete in the same class at the same pull.  This class of ‘smokers' is promoted regionally by Full Pull Productions, Inc.

 
The 2009 championship went to Nathan Graham from Greensburg, Pennsylvania with a Ford 9000 Limited Pro Tractor named “Blue Reaper”.  This tractor was originally built at Forrester Farm Equipment in Shippensburg, Pennsylvania and was equipped with a 540 cubic inch Ford Genesis engine with a very large single turbo-charger.  Graham was the runner-up a year ago and was determined to take his first-ever USA-EAST championship this season.  Nathan is always supported by the top two ladies in his family – Karen, his wife and Kayla, his 10 year old daughter.
