ABSTRACT:
A cultivating implement include a soil working tool having an elongate substantially planar blade. The blade extends sidewardly and downwardly at an acute angle to the vertical so that its plane is substantially parallel to the direction of movement through the soil and so that soil is lifted without inversion over the blade during passage through the soil. A movable extension is mounted to the blade trailing edge and is adjustable between first and second rigid positions to adjust the lifting action on the soil and thus adapt it to a wide variety of soil types and moisture conditions. At the lower end of the blade is a shoe member with an upwardly and rearwardly inclined upper surface at a leading end thereof, and an upright and rearwardly extending side surface substantially parallel to the direction of travel to provide a bearing surface for resisting lateral forces on the tool due to lifting action of the blade. The shoe member imparts lateral stability and factilitates penetration.
