The HORSCH Joker Series is a versatile lineup of compact disc harrows engineered for fast, efficient stubble cultivation and high‑quality seedbed preparation across a wide range of conditions. Beggining with the mounted Joker CT for lighter, precise operations, to the trailed Joker RT for scalable acreage, and up to the heavy‑duty Joker RX and HD for high‑horsepower tractors. The Joker family delivers aggressive soil mixing, excellent residue flow, and consistent reconsolidation.
The Joker’s DiscSystem with aggressively angled, serrated discs delivers intensive soil mixing and residue incorporation at high working speeds, helping operators cover more acres efficiently while creating fine, uniform tilth.
Paired disc mounting and generous frame clearance allow the Joker Series to handle heavy straw, cover crops, and organic matter with minimal blockages, ideal for shallow stubble cultivation and residue‑rich conditions.
A wide range of packer and finishing systems ensures uniform soil reconsolidation across the working width, promoting even moisture retention and optimal seed‑to‑soil contact for the next pass.
From the mounted Joker CT to the trailed Joker RT and heavy‑duty RX and HD models, the Joker Series scales seamlessly to match tractor size, acreage demands, and operating intensity without sacrificing performance or durability.
