| 摘要 | A system for adjusting down pressure loads on a harrow of an agricultural implement may include a base hitch member and an upper tow arm pivotally coupled to the base hitch member. First and second linkage arms may pivotally couple to the upper tow arm. A lower support arm may pivotally couple to the first and second linkage arms. A plurality of ground engaging elements may be supported on the lower support arm. A tensioner assembly may include an actuator coupled between the base hitch member and the lower support arm. The actuator may include an actuator rod that extend and retract to adjust a relative distance between the base hitch member and the lower support arm. The actuator may regulate a down pressure applied on the plurality of ground engaging elements by adjusting the relative distance between the base hitch member and the lower support arm. | ||||||
