A cylindrically shaped fulcrum member is affixed to the lower end of a garden tool such as a pitchfork, cultivator or weeder. The fulcrum member may be attached either directly to the tines or to the handle shaft if there are no tines and is located above the lowermost point of the tool. After the point of the tool is forced into the ground, the handle is moved rearwardly, the back of the fulcrum member contacts the ground and the lower end of the tool pivots upwardly braking up the soil or pulling up weeds or the like. The fulcrum member is provided with at least one bolt and nut clamping mechanism so that the member can be moved through and secured to different positions along the tines or the shaft to change the mechanical advantage of the tool.

In a cultivating tool having an elongated handle with a grip at one end thereof and a plurality of tines extending from the other end of said elongated handle, the improvement comprising a substantially tubularly shaped fulcrum member located transversely beneath said tines and contacting the undersurface of said tines and means securing said member thereto, said securing means being manually operable so that said member can be released when desired and moved along at least a portion of the length of the tines to a new position where it can again be secured, said manually operable securing means being comprised of a plurality of bolts passing from the interior of said tubularly shaped fulcrum member through spaced apart openings in the wall of said member with each bolt terminating above the front surface of a different one of said tines, a stop member mounted on the outer surface of said tubular member adjacent each of said openings, the height of said stop members above said outer surface being less than the diameter of said tines, said securing means clamping said tines between the ends of said bolts and the outer surface of said tubular member.
