  • Patent number: 9347844
    Abstract: A draft sensing mechanism for a three point hitch includes a hitch frame attached to a frame of a vehicle. The hitch frame includes left and right link supports for coupling to left and right draft links and left and right draft bars. Each draft bar has a first portion attached to a corresponding one of the link supports, and a second portion positioned rearwardly and inwardly with respect to its first portion. Draft forces applied by the draft links to the link supports are transmitted to the second portions of the draft bars. A linkage unit sums the draft forces from the draft bars and includes a draft force transducer which generates a draft force signal in response to deflection of the draft bars.
    Type: Grant

  • Publication number: 20130192854
    Abstract: A draft sensing mechanism includes a draft frame adapted to be attached to a frame of a vehicle. The draft frame has left and right supports adapted to be coupled to corresponding left and right draft links. A draft strap has a left end fixed to a front side of the left support and a right end fixed to a front side of the right support. The draft strap is deflectable in response to draft forces applied to the left and right supports. A draft sensor is attached to the draft strap. The sensor generates a draft signal in response to deflection of the draft strap.
