Horsch Joker HD heavy disc harrows

Horsch Joker HD heavy disc harrows are indispensable implements in modern farming systems. Besides their main purpose, stubble cultivation, they are often used for seedbed preparation after the plough or cultivator, and for chopping coarse crop residue or incorporating organic fertiliser.
The HORSCH Joker HD compact disc harrow became widely popular through its use in the Pronto series of combined seed drills.
Since 2013 HORSCH has offered its Horsch Joker HD compact disc harrows, the heavyweight among compact disc harrows, for cultivating maize and sunflower stubble.
The machines look massive and have a stable, rigid design. This applies not only to the frame but also to the discs and bearing units. They use sealed bearings running in oil, so they need no additional maintenance.
The high weight of the machines combined with aggressive notched concave Ø 520 mm discs guarantees that the implement bites into the soil. And the higher the speed, the better the work quality!
Disc working depth is set simply and conveniently with stops: aluminium clips on the piston rods of the roller cylinders, the hitch and, on some models, the front depth wheels.
