The ST820 has single cylinder depth control for pinpoint accuracy, reliable depth setting and low maintenance. Its mechanical linkage system translates the depth to the walking axles, ensuring that the depth is the same across the entire machine. A parallel lift mechanism between the rear walking beam and the front casters keeps the frame level, whatever the working depth. The ST820 offers unmatched crop residue clearance in all configurations. Wheels placed well to the rear also help clear trash.
Ample tires provide superior flotation.
In addition, walking beams are placed well to the rear of the frame. You get superb penetration and extremely long life. Transport safely with an over center wing-up position and heavy duty wheels and hubs under the center section. In fact, large 5-section models are equipped with an even stronger under carriage.
