The next generation of feed trailer is here. Meet our newest high capacity feed trailer. The new GEN4 features a durable design that will keep you delivering feed longer and speeds up to 8,500 pounds per minute that let you deliver feed faster! 



Atlas NXT

The Atlas NXT feed trailer features a massive horizontal-to-vertical transition with a four vane flipper that moves feed from the floor auger to vertical auger fast. This trailer will get the job done quickly. What you do with your extra time is up to you! 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.
