Mid-Size Grain Carts Corner-Auger Grain Carts

From start to finish, harvest goes smoother with a Brent grain cart. The Brent 678XL corner-auger grain cart features 630 bushel carrying capacity, making it the right size for smaller acreage requirements. The side-fold, single-auger design allows the upper auger to be longer, increasing side reach and height, which allows the operator to drop grain straight down for greater control. The 14” diameter auger provides unloading speeds up to 300 bushels per minute and the unique auger sump combined with the steep side slopes ensure quick and complete cleanout of grain during each unload.  The Brent 678XL corner-auger grain cart offers high-capacity grain handling in a mid-size package.
