HORSCH Joker RX
High-Speed Compact Disc Harrow
Turn heavy BT corn stalks into a ready-to-plant seedbed at speeds over 10 mph. Designed to maximize tight Ohio planting windows, the HORSCH Joker RX delivers fast, shallow tillage to chop tough residue, incorporate fertilizer, and level ground in a single high-speed pass.
Key Capabilities
- Heavy Residue Flow: High underframe clearance and extended spacing between the two disc rows handle massive corn fodder and thick cover crops without plugging.
- Aggressive Cutting Action: 20-inch notched discs mounted at a 17-degree angle actively pull into hard, dry ground to slice stubborn stalks and mix organic matter.
- High-Speed Acreage: Engineered to run at 10 to 12 mph with a SoftRide transport suspension system to prevent machine bouncing.
- Optimal Seedbed: Small-diameter discs spin at high RPMs to produce fine soil in the germination zone, while the rear packer consolidates the finish for perfect planter row-unit ride.
- Independent Obstacle Protection: Each disc is individually mounted on its own arm with a rubber torsion suspension to trip over rocks without lifting the entire gang out of the ground.

A: No. The machine utilizes a high underframe clearance, wide spacing between disc rows, and individually mounted discs on rubber torsion arms to keep heavy trash flowing without hairpinning or bulldozing.
Q: How deep does the Joker RX run?
A: The Joker RX is optimized for shallow primary tillage and seedbed preparation, typically working between 1 to 5 inches deep to size residue and create fine soil for the germination horizon without pulling up deep clods.
