Our Manufacturing History

Here at the hopper bottom grain trailer and grain dump body division of Integrity Sales and Service, we are continuing the time tested tradition of manufacturing a quality product: that is built by farmers, for farmers! Our founder Bob Pfister has been in continuous business here in north-east Indiana since 1965 after moving from Gibbon, Minnesota. While operating his farm during the 1960s and 1970s he dreamed of manufacturing a grain trailer that would fit each farmer’s specific needs.

Hopper Bottom Grain Trailer Conversion

This is John Pfister, Bob’s son back in 1991 putting the finishing touches on another excellent example of a custom built hopper bottom grain trailer. This was a flat bottom to hopper bottom grain trailer conversion. You can trust our years of experience, we have two generations of know-how. 

Finally, Bob Pfister started Agri-Traders, a grain trailer manufacturer in 1982, he envisioned manufacturing an extra heavy duty hopper bottom grain trailer that would stand the rigors of day-to-day crop harvest and grain delivery that farming requires. Our trailers are over-built to the strict specifications Bob Pfister has demanded from the beginning of Agri-Traders. Our Amish craftsman have two generations of core competencies; they double check all angles and use solid welds to ensure strength and durability: no skip welds here! We take the time to make sure your grain trailer or grain dump body will stand the test of time.

Once the construction of your new grain trailer or grain dump body is finished, you may select any color you wish. We sandblast, prep, prime, and paint your new hopper bottom grain trailer or grain dump body with a quality new paint job that will last. You can even give your semi-tractor a fresh matching paint job, or you may want to upgrade to a late-model used semi tractor purchased from our heavy truck sales division. We can even add a custom stripe or two-tone color pattern to your new grain trailer or grain body to give your farm business its own unique stand out image.
We look forward to serving you in constructing you brand new hopper bottom grain trailer or grain dump body today, and to meeting your forthcoming needs in the future. You can trust years of experience, company longevity, and second generation competency! Since 2001 we have been operated by second generation management and ownership, but Bob Pfister is still involved in day to day operations: still going strong!

Bob Pfister continues with us as the founder of Agr-Traders. He brings years of knowledge and expertise. Dave, Bob’s nephew, also brings the proficiency as  a second generation owner. 

Near Fort Wayne Indiana, we have upgraded to a higher capacity grain trailer manufacturing facility, but still incorporate our original time-tested model and have the same strict specifications.
