Appl. No.:

6/912962

Inventors:

Keith A. Wheeler - Blue Springs MO

Assignee:

Abstract:

An agricultural implement is equipped with a plurality of earthworking tools spaced from one another in the fore and aft direction. One of the tools is adjustable between working and nonworking positions on a main frame by a hydraulic actuator connected to the main frame by a resiliently cushioned support which includes a spring loaded link. The one tool includes a coulter gang supported on a subframe by a pair of U-shaped springs. The deflection of the U-shaped springs and the spring loaded link allows the coulter gang to pass over relatively large boulders or the like without raising the implement frame to a significant extent and without causing the relief valve in the actuator hydraulic system to open.

Abstract:

A combine lateral tilt assembly which attaches a crop harvesting header to a combine includes a stationary extension of a combine feeder housing with a pair of rollers positioned on an upper surface thereof. A movable member is removably attachable to a header and includes a pair of roller tracks positioned to receive respective ones of the rollers on the stationary extension such that the movable member is substantially supported by the rollers. The movable member is mounted to tilt while riding on the rollers about an axis which is formed by a pivot pin positioned in a bottom portion of both the movable member and the stationary extension. A single hydraulic piston and cylinder unit connects between the movable member and the stationary extension to thereby selectively tilt the movable member, and the attached header, laterally relative to the combine.
