Stubble Disc Harrow Notched Blade Tractor Pulled 7.5 Meter Width for Broadacre Residue Management

On broadacre blocks, residue is not waste. It is moisture, organic matter and wind protection, and the trick is to cut it down and mix it in without burying it or leaving a mat that blocks the following seeder. This stubble disc harrow is set up for exactly that job. The front gang of notched discs slices standing stubble and root balls, and the rear gang of plain discs levels and firms the surface behind it. Contractors running it behind 180 hp tractors pull through cereal stubble at working speeds that keep the day economical, even when the straw load is heavy.

• Notched and Plain Disc Gangs: Notched blades up front for penetration, plain blades at the rear for levelling, one pass does both.
• Hydraulic Crumbler Roller: A 40 cm roller breaks clods and leans on the soil to conserve moisture, replacing a separate pass.
• Adjustable Gang Angle: Angle can be moved to change how aggressively residue is cut, from light mixing to full incorporation.
• Heavy 62 cm Discs: Large diameter keeps the tool rolling over heavy stubble instead of riding up on it.
• Wide Swath Coverage: Up to 7.5 m working width covers a 300 hp tractor footprint efficiently.
• Maintenance-Free Hubs: Forged bearing arms and sealed units keep daily greasing to a minimum during harvest windows.

Broadacre residue management and secondary tillage after cereals, canola and pulses. The harrow carries stubble through to seeding on no-till and minimum-till programs, and works fallow ground to control weeds between crops. It also suits large pasture renovation and stubble mulching programs where a fast, wide tool is needed to cover ground before the weather turns.

Wide units ship in sectional form to keep container loading practical, with the gangs, roller and frame crated separately and clearly marked for reassembly. Discs are checked for run-out, and each bearing arm is assembled and rotated before packing. Production is governed by ISO 9001:2015 procedures and the harrow carries CE marking. A full set of wear parts, including disc blades and bearing arms, is available as a stocked spare lines.
