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 1990 we purchased what is now called Plant 3 with the Cleland Manufacturing product of Stake bed and Flat bed Truck Bodies.  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.

Plant 1 is situated on 4 acres with 33,000 sq. ft.. It currently houses the Main Office, Mercury Sales office, Machine Shop, and A&G Mercury Parts warehouse.

Plant 2 was the first plant for A&G Mfg. Co. Inc..  The original building was built in 1975.  Since then it has had 5 expansions. Plant 2 is situated on 11 acres with 54,000 sq. ft of manufacturing space.  It is currently Heavy Fabrication, Assembly of Tow Tractors, Abrasive Blasting, Wet Coat and Powder Coating.

Plant 3 is situated on  3.7 acres with 22,800 sq. ft. of manufacturing space. Plant 3 was purchased  in 1990 and was formally known as Cleland Manufacturing. Their main product was flat bed and stake beds for utility trucks. Although Plant 3 still manufactures truck beds they  have expanded to their production to include trailers and cabs for A&G Mercury as well as light fabrication job shop work.
