DURABILITY TO TAKE ON THE TOUGHEST CONDITIONS
Even under ideal field conditions, higher operating speeds increase equipment wear and tear. Our beefed-up shank assembly design stands up to the challenge.
FORCE AND FLEXIBILITY, BALANCED
The shank assembly design on the Tiger-Mate 255 not only provides the consistent, flat subsurface floor necessary for fast germination and even emergence but also helps you complete the task faster and more efficiently. Operating at higher speeds — up to 10 miles per hour — means faster-changing conditions across the field. We balanced this beefier shank with a proportional increase in spring thickness, so it flexes prior to spring compression and provides a 20 percent increase in holding power . This balanced flexing helps maintain a consistent depth and keep sweeps parallel to the ground and on a level plane from nose to wing even through those compacted areas left by the combine or grain cart.

Stronger compression spring holds sweep in place during work, while adding protection to the assembly during rocky conditions. Compared to a stretch spring, compression spring retains holding power throughout its life. The shank channel guard provides stability and even side-to-side loading for enhanced shank durability.
Hardened, dual greaseless pivot-point bushings last longer and require less maintenance. Plus, dual bushings help ensure the pivot point doesn’t gall and wear out, which could allow the shank to move laterally, creating an uneven subsurface floor. The shank stop , which initially positions the sweep parallel to the ground, is positioned for precise consistency and durability. The larger main shank pivot bolt holds tight to maintain consistent spring pressure for a level subsurface floor.
