摘要
A depth-adjustment assembly for ground openers of an agricultural implement. The ground openers each include an opening disc, a gauge wheel, and a support assembly securing the ground opener to the agricultural implement. The support assembly is configured to raise and lower the ground opener with respect to the ground and/or to adjust a down-pressure of the ground opener. The depth-adjustment assembly comprises for each of the ground openers, a linkage assembly and a depth-adjustment arm configured to adjust a relative position between the opening disc and the gauge wheel. At least a portion of the linkage extends in parallel relationship with the support assembly. The depth-adjustment assembly further comprises a laterally-extending common pivot bar. Each linkage assembly is secured to the common pivot bar, such that rotation of said common pivot bar is configured to simultaneously adjust the relative position between the opening disc and the gauge wheel of each of the ground openers.
