ABSTRACT:
A wire gate control apparatus includes a base sleeve having an aperture near the top thereof and a longitudinal slot at the bottom thereof and further having a keeper biasedly mounted at the aperture, and further includes a plunger slidably disposed within the sleeve and having first and second apertures spaced apart and a horizontal slot disposed between the first and second apertures and adapted to engage the keeper to lock the plunger in predetermined place and having a detent adapted to slide within the longitudinal slot, and also includes an arm pivotally mounted near its bottom to a pair of brackets fixedly attached to the sleeve, and having wire-connecting member spaced along the length thereof. The detent contacts the arm to close the wire gate and moves out of contact with the arm to lower the arm and open the wire gate. Preferably, a loader mounted to a tractor forces the plunger downwardly to open and closed the wire gate without the user ever having to manually open and close the gate with one's own hands.
