An automatic locking ball coupler (10) for a power take off includes a ball keeper (12) connected to the power take off and having a longitudinal axis and openings (15,16,17) in a cylindrical surface thereof. Locking balls (11) are received in the openings (15,16,17) and can move radially with respect to the axis of the cylindrical ball keeper (12). A ball collar (20) is positioned around the cylindrical ball keeper (12) and has a plurality of internal circumferential rings (21,22,23) and recesses (24,25,26,27) between each ring. The ball collar (20) can slide axially with respect to the longitudinal axis of the ball keeper (12) between a coupled position in which the locking balls (11) are on the rings (21,22,23) and an uncoupled position in which the locking balls (11) are in the recesses (24,25,26,27). |
