A wing section equipped rod weeder implement is provided wherein the implement includes a center section and a pair of opposite side wing sections which may be swung upwardly to retracted positions for moving along roadways or through narrow fence openings. The center section rod weeder shaft is driven by a reversible variable speed hydraulic motor and the opposite ends of the center section rod weeder shaft include universal joints removably supported therefrom for selective reversed mounting on the center section rod weeder shaft ends and each universal joint defines a swivelly supported inwardly tapering threaded socket. The adjacent ends of the wing section rod weeder shafts include tapered threaded male ends removably threaded within the sockets. The threaded connections are of the non-jamming type wherein they may be readily unthreaded. Further the universal joints are equipped with releasable latch structures which automatically retain the universal joints in centered positions responsive to the tapered male rod weeder ends being initially unthreaded therefrom and automatically release to enable full universal movement responsive to final threaded engagement of the tapered male rod weeder ends therewith.
