THREE-POINT HITCH ASSEMBLY |
摘要 |
<p>THREE-POINT HITCH ASSEMBLY A three-point hitch assembly for attachment to a tractor includes a pair of lower lift arms adjustably coupled to an upper lifting assembly which can be raised and lowered by a pair of hydraulic cylinders. In order to provide a float action of the lower lift arms, a lever coupling the upper end of the pistons of the hydraulic cylinders to the lifting assembly can be latched and unlatched to pivot relative to the lift assembly. The cylinders are coupled in series so as to ensure even lifting of the lift assembly.</p> |
