A & G Manufacturing Co., Inc. was founded by Arvin Shifley & Glen Shifley Sr. in 1971. We are still a family owned company today. We started out as a Job Shop facility with machining, welding, fabricating, and finish painting. In 1975 we built our first building which has had 5 expansions and is now called Plant 2. In 1993 we purchased what is now called Plant 1. In 1996 we purchased the Pettibone Mercury Tow Tractor line after fabricating and assembling the units for them for several years.
