Abstract
A rotary hoe extension and kit for extending the effective length of one set of arms of a rotary hoe to increase the separation of the axes of rotation of adjacent rows of hoe wheels to a distance greater than the diameter of the hoe wheel while maintaining lateral wheel spacing. The extension includes a body member, having an upper end or first portion including a U-shaped alignment member which surrounds the existing rotary hoe arm on three sides to provide a rigid unit and a lower end or second portion having an aperture therethrough for attachment of a hoe wheel thereto. The lower end of the arm and lower end of the extension are in alignment with each other thereby allowing for maintenance of the lateral wheel spacing. A connector arrangement is provided to secure the extension to the support arm.
