SPRING BIASED COUPLING MEMBER ON A DISK GANG FOR DRIVING ENGAGEMENT WITH A FOLDING WING GANG COUPLING MEMBER

摘要

A coupling for interconnecting a generally stationary main disk gang of a disk harrow and a wing gang movable to a position axially aligned with and establishing an extension of the main disk gang, the coupling including a first coupling member having radial drive lugs and supported by one of the cooperating pair of disk gangs for axial sliding, a second coupling member supported in axial relation on the other of the disk gangs and having recesses formed to receive the drive lugs in driving relation, and spring means operative with the first coupling member to allow the disk gangs to be brought into generally axial alignment and effect driving coupling therebetween without radial alignment of the driving lugs and receiving recesses therefor.
