Implement transporting device

A device of the kind described, comprising:

• an elongated implement having an elongated implement frame, implement wheels pivotal about an axis parallel to the longitudinal axis of said implement, and tongue means extending transversely from said longitudinal axis of said implement intermediate the opposite ends thereof;
• a transporting wheel assembly mounted to said implement frame intermediate the opposite ends thereof, said wheel assembly comprising a pair of spaced-apart vertical legs, each of said legs having upper and lower leg members which are vertically extensibly mounted with respect to one another, each of said lower leg members having a transporting wheel mounted thereon for rotation about an axis transverse to the longitudinal axis of said implement;
• power means connected to said legs for causing vertical extensive movement of said leg members from a retracted position wherein said transporting wheels are above said implement wheels to an extended position wherein said transporting wheels are below said implement wheels;
• a transporting tongue assembly having a base portion rigidly secured to one end of said elongated implement frame, and a transporting tongue for attaching to a pulling vehicle pivotally mounted to said base portion for swinging movement about an axis transverse to the longitudinal axis of said implement frame, and
• a hydraulic cylinder for causing pivotal movement of said transporting tongue about said pivotal axis, having first and second ends, said first end connected to said tongue at a point spaced from said pivotal axis of said tongue and said second end secured to said implement frame by a U-shaped frame having a horizontal base and two upstanding spaced apart legs, bolt means attaching said U-shaped frame to said implement frame with said tongue extending between said upstanding legs of said U-shaped frame and said second and of said hydraulic cylinder being attached to said horizontal base of said U-shaped frame.
