Abstract
The present invention is directed to a flexible and resilient intermediate support member for supporting the grain box of a grain drill. The intermediate support member comprises a vertical frame member rigidly secured to the grain box and a horizontal frame member rigidly mounted to a transverse support frame. A guide pin projects upwardly through the horizontal frame member and engages the bottom of the vertical frame member. The guide pin is formed by a bolt and a spacer, that are slidably mounted to the horizontal frame member. An engagement nut is mounted to the threaded end of the bolt engages the bottom portion of the vertical frame member. A bearing washer is located between the engagement nut and the spacer. A spring is positioned between the bearing washer and the horizontal frame member. A trapping washer located between the head of the bolt and the spacer is used to trap the guide pin to the horizontal frame member.
