A shear bolt coupling incorporated in a drive transmission of an agricultural baler comprises a first rotatable member, a second rotatable member disposed coaxial with the first rotatable member, and a shear bolt operatively interconnecting the first and second rotatable members for transmitting power therebetween during normal operation. The shear bolt is arranged to shear off under excessive load conditions in order to interrupt power transmission between the rotatable members and thereby permit the rotatable members to move relative to each other. A shear bolt introducing lever is operatively associated with either the first or the second rotatable member for urging the shear bolt into a drive coupling position wherein the rotatable members are drivingly coupled together. The shear bolt introducing lever is movable relative to the rotatable members between an inoperative position clear of a shear bolt introducing area of the rotatable member having the shear bolt introducing lever associated therewith for enabling insertion of a new shear bolt, and an operative position for urging the new shear bolt into the drive coupling position.
