Rippled coulter blades cut through surface residue such as cornstalks, wheat stubble, or other heavy crops to help reduce plugging.
The ripple on the blade bites into the soil to promote turning the blade in wet and/or firm soil, as well as lighter, drier soils.
Cushion or shear-bolt designs are available.
Cushion-designed coulter blades
- Automatically returns the coulter to the operating position once the obstruction is passed.
- Saves time by eliminating the need to stop and replace shear bolts.
- Unique rosette bracket used to adjust the coulter depth. Simply loosen one bolt and swing the coulter up or down to the desired height.
- Standard does not move, so maximum trash clearance is retained.
- Protector bolt (arrow) will yield if the obstruction height exceeds the deflection range of the coulter, thus preventing serious damage to the coulter.
- 457-mm or 508-mm (18-in. or 20-in.) rippled blades are available for good cutting action. The maximum working depth is as follows*:
- For the 457-mm (18-in.) coulter blade, the working depth is 483 mm (19 in.)
- For the 508-mm (20-in.) coulter blade, the working depth is 457 mm (18 in.)
*NOTE: When ripping in fields with obstructions, it is necessary to restrict the working depth in order to give the coulter space to travel over obstructions. Without coulters, the maximum working depth is 584 mm (23 in.) for shear-bolt standard and 559 mm (22 in.) for safety-trip and spring-reset standards.
Shear-bolt design coulter blades
- Provides economical alternative for protecting coulters in fields with few obstructions.
- 457-mm, 508-mm, or 559-mm (18-in., 20-in., or 22-in.) rippled coulter blades are available for good cutting action. The maximum working depth is as follows:
- For 457-mm (18-in.) coulter blades, the working depth is 483 mm (19 in.)
- For 508-mm (20-in.) coulter blades, the working depth is 457 mm (18 in.)
- For 559-mm (22-in.) coulter blades, the working depth is 432 mm (17 in.)
