Hydraulic shank designs offer several advantages over traditional rigid shear pin models, however these come at the expense of increased cost and maintenance. In this article, we compare the pros and cons of rigid vs. hydraulic shanks in a deep ripper plough to enable you to choose which breakout design suits your operational needs for best performance.
Shank protection is via a shear pin inserted in lieu of one of the mounting bolts at the top of the shank. These shear pins are designed to fail at a predetermined force. Once this force is exceeded the pin fails and the shank lays back. Shear pin failure is finite and a ‘failed’ shear pin cannot be reused.
The procedure to replace a shear pin is as follows:
Rigid Shear Pin shanks are available on all models in the Agrowplow range.
Shank protection is via a hydraulic recoil system. The system is pressurised from oil in the tractors hydraulic system. As the shank encounters an obstacle the oil is forced out of the cylinder back into the circuit increasing the pressure in the accumulator. When the obstacle is cleared the accumulator forces the oil back into the cylinder returning the shank to its operating position.
The pressure in the operating system can be adjusted according to the operating conditions by increasing or decreasing the oil level in the circuit. A shut off valve is located near the base of the accumulator to either open or close the circuit from the tractors hydraulic system.
Hydraulic Recoil shanks are available on all models in the Agrowplow range except the AP11.
Single disc openers are ideal for heavy soils and high residue conditions, ensuring precise seed placement and minimal disease risk. Double disc openers excel in light soils and allow for faster planting, making them suitable for well-prepared ground. Learn more about their unique benefits and applications in this article.
When it comes to choosing between a tyne or disc opener for your seed drill, each option comes with its own set of advantages and considerations. In this article we compare the pros and cons and discover which options are best suited to certain conditions.
