What we do
With a knowledge of diesel engines and the agriculture industry, Nathan Frey Farm Equipment was started in 1998. Nathan Frey Farm Equipment specializes in leading edge tillage equipment and grain trailers as well as used farm equipment.
History in Agriculture
At just 18 years of age, Nathan Jay Frey started his farming operation with a Farmall “M” and two bottom plow. He also pursued his degree at Northwestern College in Diesel Mechanics and Welding. Over the next two decades, the farming operation has grown into innovative farming practices and modern farm equipment on the same farm his ancestors homesteaded on in 1845.
More than trailers
With a knowledge of farm equipment sales and always a dream to manufacture, the Fuel PRO® Trailer brand was born. NJF Manufacturing LLC. also manufactures Frey Livestock Gates® and Freeze Guard Waterers®.
Steadily growing
In 2011, NJF Manufacturing LLC. was founded by Nathan in Upper Sandusky, Ohio. With a personal motto, “Don’t Ever Give Up”, he has been able to steadily grow NJF Manufacturing LLC.
With the next generation starting to work at NJF Manufacturing LLC, Fuel PRO® Trailers are here to stay.
