J&M History


Honesty, Hard Work, and a Firm Faith in God!

J&M’s founders, Jerome and Maurice Grieshop, were raised in the small farming community of Fort Recovery, Ohio. Growing up in a large family, they were taught the importance of hard work, the value of a dollar and the necessity to treat others the way they would want to be treated. Being farmers themselves, they understood the hard work that was necessary to produce a quality product and the importance of having equipment designed to make farm work easier and more efficient. In 1960, with a firm faith and trust in Almighty God, they started the J&M Manufacturing Company with these qualities as their guiding principles for how they would design products and conduct business. It has proven to be a very successful recipe that has been passed on and continues to be the key to the ongoing success at J&M today.


J&M Manufacturing Co., Inc. has been a leading manufacturer of grain handling equipment for over 50 years. Located in the agricultural community of Ft. Recovery, Ohio, J&M has consistently provided innovative, dependable, and high quality products to farmers throughout the United States and Canada, as well as overseas.

Starting in 1961, we built our first gravity wagon, holding 110 bushels, for a local farmer. By 1975 our boxes grew to 350 bushel capacity, selling over 8,000 units that year throughout the grain belt region of the United States. Today our wagons hold up to 760 bushels.

In 1987, we designed our first grain cart, a side folding auger cart holding 450 bushels. In 1988 we introduced our Front-Folding Corner Auger Cart which continues to be the industry standard today. This cart design utilizes a single auger that provides 100% visibility of the auger while unloading and equally important 100% visibility during the folding sequence. A corner auger sump design also provides superior cleanout. Innovative options, like our patented Hydraulic Flow Control Spout, Electronic Scales, Dual Wheels, Tracks and Roll Tarp continue to make the J&M Front-Folding Auger Cart one of the most demanded carts on the market today. Our grain carts have grown in size and unloading speed - up to 2,350 bushel capacity with a 22" diameter unloading auger, delivering 800+ bushels per minute.


Today, along with gravity wagons and grain carts, our product line up includes bulk and pro-box seed tenders, nitrogen applicators, soil conditioners, hay wagons, header transports as wells as bolt-together products for container shipment. No matter what product you choose, you can be assured that our products are built to handle your toughest demands year after year.
