AGRICULTURAL, FORESTRY AND HORTICULTURAL MACHINE

摘要

Structure such as an agricultural, forestry or horticultural machine with a parallel bar linkage assembly (18) adjustably mounting an implement (20) such as a spray assembly for vertical movement relative to the ground. The linkage assembly includes a first and a second parallelogram (48, 50) having a first common link (30). A first portion (54) of the link (30) forms one side of the first parallelogram (48) and a second portion (58) of the link (30) forms one side of the second parallelogram (50). The two parallelograms (48, 50) save space and improve implement positioning and action radii as compared to conventional linkage constructions.
