ABSTRACT:
A PTO master safety shield is provided having a cut-out in the upper surface thereof. A door is pivotally mounted within the shield to close the door and biased by springs into the closed position. If the center link of a 3-point hitch is lowered to where it contacts the lip of the door, it will simply press the door downwards. Upon subsequent lifting of the center link, the springs will move the door back into the normal position. The main body of the master field also is pivotally mounted to flip up to a raised position. The door is provided with arms which engage slots at the back of the master shield. If the master shield is left in the raised position and the center link is lowered to where it contacts the door, the door will pivot, the arms of the door will lift the back end of the master safety shield and force it forward until it falls down into its normal position.
