Feed Trailer Comparison Guide

Atlas NXT

This trailer is the industry leader for unloading speed with capacities as high as 8,500 pounds per minute and averages of 7,000 pounds per minute. The massive horizontal-to-vertical transition houses a four vane flipper that moves feed from the floor auger to vertical auger fast. Available in rear or front unload.


Big Boy

Lightweight for maximum scaling but built strong for minimum maintenance. This trailer features one single U-trough auger that delivers feed to the vertical unload auger. This trailer is the Big brother of the original Sudenga truck, the "T" Series. Available in rear or front unload.

ST Series

The ST Series has twin floor augers that allow for a lower body height and also increased stability since more of the load is closer to the frame. Steep 45 degree sloped sides make for reliable unloading and the large lower body means more capacity. Excellent clean out and little cross-contamination are two benefits of having twin floor augers. Rear unload only.

NXT Series

The NXT has no cross auger and instead uses an 18" diameter flipper attached to the bottom auger that propels the material to the vertical auger. Hence the name NXT, meaning no cross trough. Fewer moving parts mean lower costs and reduced maintenance. The true ninety degree vertical auger reduces stress at the vertical-to-discharge auger connection. Rear unload only.
