摘要 |
<p>A disc harrow composed of one or more disc gangs has a subframe coupled to the disc gangs to move the disc gangs in response to variations in farmland terrain to limit the impact of obstructions when encountered during the harrowing process. When the obstruction is cleared, the subframe automatically returns the disc gangs to their pre-obstruction position. In addition to reducing the potentially-damaging impact of obstructions, the subframe also maintains a more consistent reel depth during undulations or changes in the farmland terrain, such as during harrowing of slopes or unleveled fields such as valleys, near waterways, and along fence rows.</p> |
