Bring the grain in from the field. The JD 8320R tractor with its dual front and rear tires can pull the heaviest load of grain. The J&M grain cart rides on soft plastic tires. The auger pivots to unload the grain into the elevator. The 8320R has a sturdy die cast body with a osciallating die cast front axle. Soft plastic tires makes for a smooth ride. The grain cart has a die cast frame and box which can take the abuse. Imagine climbing the ladder to look into the box to see how much grain is in the box.
