300mm Longer than Standard
Extended screens have a 300mm longer grading length and two rows of agitators better separation of tubers can be had in extreme conditions. When grading with long tuber varieties the extra length and extra agitation improves separation.
Anti-Cut Rollers
Each screen is fitted with an ejection system which alleviates damage to long tubers.
Drive Motors
Each Easy-Grade screen section has two mechanical variable speed motors. One is for the forward speed of the screen. One is for the speed of the agitator rollers. By adjusting the speed of each motor the desired separation of tubers and tons per hour are achieved. (See ‘operation’ page)
Side Delivery Conveyor
Each Easy-Grade screen section has a conveyor for the tubers which pass through the screen and delivers the crop to the side on a 1200mm wide conveyor. This has an endless self-tracking belt, is fitted on rollers and has a reversing switch for belt direction enabling it to project either or both sides of the machine.
