Abstract
A swather rake attachment assembly that quick connects to a front of a swather and includes two rake arms that each include lateral holding arm pivot connections to a base frame where the lateral arms are each pivotally coupled to arched reinforcement members by a torsion assembly that is coupled to a parabolic curved tool bar that includes the parabolic curved tool bar and arched reinforcement members, and includes a Z-bar coupling of the two rake arms together that control the height of the arm rake assemblies.
Claims7
A system for agricultural raking comprising:
- a rake assembly removably attachable to a swather, wherein the rake assembly comprises two arm assemblies having a plurality of rake wheels couples thereto wherein the rake assembly includes a base frame removably attachable to the swather by one or more connection points, said base frame has two rake arm assemblies extending horizontally therefrom, and each said rake assembly has a lateral holding arm connected to said base frame using a primary pivot connector, which said lateral arms are pivotally coupled to two arched reinforcement members via a pivoting torsion assembly, with said pivoting torsion assembly being further coupled to a parabolic curved tool bar;
- a plurality of bracing members are interposed between said parabolic curved tool bar and said two arched reinforcement members;
- said plurality of rake wheels are pivotally coupled to said parabolic curved tool bar;
- and a Z-bar couples said two rake arm assemblies together and is configured to control the height of said arm rake assemblies.
1 more element
A rake arm assembly, comprising:
- a plurality of rake wheels configured non-linearly for a displacement of raking pressure;
- said rake wheels are coupled to a parabolic curved tool bar;
- and wherein one or more arched reinforcement members are coupled to said parabolic curved tool bar through a plurality of bracing members.
