Big Boy Front Unload

Find a Dealer

The front unload Big Boy trailer makes feed delivery as simple as it gets with faster, easier setup times. The front unload style not only offers greater visibility to the operator but also makes it easier to position, cutting the time required to deliver a load. The Big Boy feed trailer features one single U-trough auger that delivers feed to the front-mounted vertical unload auger.

Unload speed: 3,000 pounds per minute     Capacities: 908-1,924 cubic feet
