Rotary hoe extension

A conversion kit for extending the effective lengths of alternate support arms in a rotary hoe mechanism which includes a plurality of support arms connected to a tool bar and a rotary hoe wheel rotatably connected to one end of each support arm, the elements of the kit including an extension including a body member, having an upper end and a lower end;

• connector means for connecting said extension to alternate support arms for movement therewith;
• alignment means integrally formed at one end of said extension including a U-shaped bracket adapted to surround the support arm on three sides to align said extension with the support arm;
• axle means at the lower end of said extension for rotatably supporting a rotary hoe wheel;
• and a stop member adapted to be positioned on the upper end of the support arm to which said extension is connected to limit the rotation of same, whereby, upon connection of said conversion kit to alternate support arms the effective length of the alternate support arms is increased a sufficient distance such that the axes of mounting of adjacent hoe wheels are offset in the direction of hoe travel an amount greater than the diameter of the hoe wheels thereby assuring no overlap of the rotary path of adjacent hoe wheels.
