Abstract
A castor wheel support for a towed agricultural implement having a frame positioned parallel to the soil over which the implement is towed. Parallel links interconnect the castor support with the frame. The castor support has a spindle with a longitudinal axis A for supporting a castor mounting structure for pivoting movement. The castor mounting structure supports an axle hub assembly and a wheel. The axis A of the spindle is angled forward 3 degrees to minimize wobbling.
Claims7
An agricultural implement for towed movement in a forward direction over the soil, said implement comprising:
- a frame extending laterally relative to the direction of movement and in a plane parallel to the plane of the soil over which it moves;
- a base;
- an articulated parallel link structural interconnection between said base and said frame for maintaining a constant orientation between the base and said frame;
- a spindle extending downward from said base and having a longitudinal axis A;
- a castor mounting structure having a bore received over said spindle to permit pivoting movement about said spindle and an axle for rotatably mounting a wheel;
- a wheel mounted for rotation on said axle;
- and,
- wherein the axis A of said spindle is angled from a right angle orientation relative to the plane of said frame to inhibit oscillation of said castor support assembly.
