ALST Series (Aluminum ST)

Find a Dealer

The ALST feed truck (Aluminum ST Series) from Sudenga features twin screw floor augers that allow for a lower body height and increased stability since more of the load is closer to the frame. Lower body height is ideal for locations with overhead clearance issues. The steep 45 degree sloped sides make for quick unloading and the large lower body means more capacity.

Unload speed: 3,500 pounds per minute      Capacities: 471-1,239 cubic feet
