Single Screw Front Unload

Find a Dealer

One single U-trough auger delivers feed to the front-mounted vertical unload auger on this feed trailer. Due to the greater visibility offered to the operator front mounted unload augers are easier to position; cutting the time required to deliver a load of feed.

Front unload trailers give the driver a better view when positioning the discharge auger for unloading. With faster, easier setup times, Sudenga front, unload "Big Boy" trailers make feed delivery as simple as it gets.

Front unload trailers have the unloading auger system over the drive axles, reducing rear axle weight and making it easier to scale the load.
