| 94 | Variable wave coulter | US11237142 | 2005-09-28 | US07497270B2 | 2009-03-03 | Douglas G. Bruce |
| The present invention provides a wavy coulter having a plurality of variable-amplitude waves, each wave defined by a crest and an adjacent valley. The coulter is mounted on an implement such that a leading peripheral edge of the coulter rotates in a downward direction as it enters the soil. The waves having larger amplitudes of deviation from flat provide a driving force for turning the variable wave coulter. The waves having smaller amplitudes of deviation from flat provide penetration into the soil. The result is a coulter that is forgiving in both wet and dry soil conditions. | ||||||
