摘要:
A pivot limiting device for an agricultural implement is disclosed. The agricultural implement includes a first frame section pivotally coupled to second frame section at a pivot location. The device includes a compression structure having a spring compressed to a preset load. The compression structure is coupled to the first frame section. A plunger includes a first portion positioned adjacent the second frame section and a second portion positioned adjacent the compression structure to move relative thereto between a first position placing no additional compression on the spring when the second frame section pivots in a first direction and contacts the plunger with a first force less than or equal to the preset load, and a second position further compressing the spring when the second frame section pivots in the first direction and contacts the plunger with a second force greater than the preset load.
