Specifications for
The General Model GG
“I have researched the following information through all of the BF Avery manuals and salesman’s price books for the BF Avery line from the past years that I have worked in agricultural sales. I also studied the differences in the BF Avery tractors that I personally own and it is my opinion that the list of years along with serial number breaks and production changes are as accurate as can be determined for these tractors.” Cork Lemmon, Farm Implement Salesman and BF Avery Collector, May 2007
All of the BF Avery production records were supposedly destroyed when the company merged with Minneapolis Moline in 1951.
These specifications apply to the Wards Twin Row and CO-OP Models G and B1 as well.
