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.

Cette invention concerne une rallonge de houe rotative et une trousse de montage permettant d'augmenter la longueur efficace d'un jeu de bras de la houe et accroître la distance de séparation des axes de rotation de rangées adjacentes de roues à pointes à plus d'un diamètre de roue à pointes tout en maintenant l'espacement latéral de celles-ci. La rallonge comprend un corps dont l'extrémité supérieure se termine par un élément d'alignement en U qui entoure le bras porte-roue existant de la houe sur trois faces pour constituer un assemblage rigide et dont l'extrémité inférieure comporte un orifice destiné à recevoir l'axe d'une roue à pointes. Les extrémités inférieures du bras existant et de la rallonge se trouvent dans un même plan vertical, ce qui permet de maintenir l'espacement latéral des roues à pointes. L'invention concerne également un connecteur de montage de la rallonge en bout de bras de la houe rotative.
