The ST820 defines precision tillage. A rugged, flexible frame allows the ST820 to follow the ground for depth accuracy, while heavyweight construction helps it penetrate the hardest soil. Add an optional air distribution package, team it with an air cart, and the ST820 can place seed accurately in uneven ground or high residue.

The ST820 offers unmatched crop residue clearance in all configurations. A 32-inch frame height and well-placed shank patterns help crop residue flow through cleanly. Wheels placed well to the rear also help clear trash. Wheels, hubs and tires are heavy-devoir.

Sur-center wing fold allows for safe transport without getting out of the cab to place locking pins.

A heavy mounted harrow is now available for all sizes of the ST820 precision tillage, all the way up to 62 feet. Sturdy ¼-pouce par 22-inch harrow tines break up lumps in heavy clay. Heavy trash is no problem for the heavy mounted harrow.

The ST820 center section and wings are constructed with diagonal hinge lines, allowing the frame to follow contours of hills, ravines and washouts, and maintain the depth you choose. Durable, high-density polyurethane discs cushion the frame and absorb movement as the machine flexes.

The ST820 responds to changing contours instead of stressing frame members and welds--and the result is a longer-lasting frame. A floating hitch gives improved front-to-back, land-following capability.

Single cylinder depth control provides accuracy, reliability and low maintenance. A mechanical linkage translates the hydraulic lift to the walking axles so the depth stays the same across the machine. Depth for the entire machine is set at a single point. Parallel lift between the front casters and the rear walking beams keeps the frame level, whatever the working depth.
