Rigid Shanks Vs. Spring Shanks Comparison


This is a comparison of rigid shanks and spring shanks. The Till-Ease Model 543 comes standard with 5 rigid shanks. The pictures below were taken to show the clear advantage of rigid shanks. To conduct this test, the Model 543 was run with 3 rigid shanks and 9" field cultivator sweeps. The Model 543 was then equipped with three spring style shanks with 7" wide field cultivator sweeps.
The rigid shanks have no trouble sinking into the ground. Without a way to control the depth, the Model 543 would easily sink deeper than an ATV could pull. Rigid Shanks
The Shank Comparison There is a clear difference. The section to the right was done with rigid shanks and the left was done with spring shanks. Spring shanks tend to spring back and the sweep angle is severely changed. This causes the sweep to drag instead of shear and heave the ground.
Surprisingly, the spring shanks with 7" sweeps pull about as hard as the rigid shanks with 9" sweeps. So not only are the sweeps wider on the rigid shanks but the rigid shanks are tilling roughly twice as deep. Spring Shanks
