Abstract: A self-aligning driveshaft coupler includes a receiving clutch mounted to a driveshaft and a locking clutch assembly mounted to an implement. The locking clutch assembly includes a collar and a yoke that rotate together, and a spring between the collar and the yoke. A locking pin may be pivotably attached to the yoke to move a projection on the locking pin in and out of the retaining groove. A plurality of drive pins extend axially from the collar. The spring biases the drive pins into engagement with the receiving clutch when the locking pin projection is in the retaining groove and the output shaft and receiving clutch are rotated less than 180 degrees.

Abstract: A self-aligning driveshaft coupler includes a receiving clutch having a spiral channel around its neck, and a locking clutch assembly with a first ring shaped member and a second ring shaped member that rotate together. A locking pin extends radially from the second ring shaped member and into the spiral channel and pulls the locking clutch assembly toward the receiving clutch as the receiving clutch rotates. A plurality of drive pins extend axially from the first ring shaped member and engage the receiving clutch when the locking pin is at the end of the spiral channel.
