Demco's grain cart is built rugged for heavy loads. The chassis is extra heavy duty to stand up to fields with imperfect terrain when the cart is fully loaded. The Posi-Flow designed box insures hassle free unloading.
The auger folds forward to provide excellent visibility of the grain flow when unloading. Driven by an automatic over-running slip clutch PTO shaft, the balanced auger and gearbox are protected from high torque start-ups associated with handling high moisture grain.
