The Simonsen BFTSTRTA top auger trailer mounted tender is the workhorse of the Simonsen lineup. The 10x13x10 delivery auger system, large trap openings, and steep slopes combine to offer unloading speeds of up to #3500 per minute. The rotating delivery auger allows for filling of multiple compartments without the need for repositioning. The 19 foo long delivery auger will make finning any applicator easy. Discharge heights of over 20 feet high and a long reach allow applicators to park away from the tender keeping your equipment and personnel safe from harm. The self-contained diesel engine power pack shown is a popular option available on all BFT series side and top auger trailer mount tenders. We sell new Neville trailers built to your desired length though 36' and 44' lengths are most common.
