Foldable implement with raisable tool assembly

In a folding implement provided with a pair of tool supporting beams swingable horizontally on a frame of the implement between laterally oppositely extending working positions and generally fore-and-aft extending transport positions with respect to the normal path of travel of the implement, the improvement comprising:

• a tool assembly mounted on the frame for vertical swinging movement between raised and lowered positions;
• and
• structure for raising said assembly to said raised position in response to swinging of the beams to said transport positions and for lowering said assembly to said lowered position in response to swinging of the beams to said working positions,
• said structure including at least one push rod between at least one of the beams and the assembly,
• said push rod being provided with a pair of universal joints at its opposite ends.

• and
• structure for raising said assembly to said raised position in response to swinging of the beams to said transport positions and for lowering said assembly to said lowered position in response to swinging of the beams to said working positions,
• said structure including a pair of push rods each connected at one end to a corresponding one of said beams and at the opposite end to said assembly.
