Bale shape monitoring apparatus for use in combination with a round baler having an expandable bale forming chamber. The apparatus alternately illuminates first and second indicator lights in response to predetermined expansion of the bale forming chamber. The apparatus includes first and second electrical switches arranged in quadrature and connected to the first and second indicator lights by a microcomputer, and a plurality of cam lobes formed on the outer periphery of a ring for activating the switches. A method for monitoring bale shape in a round baler utilizes the first and second indicator lights and the first and second electrical switches. According to this method, the first indicator light is illuminated by opening the first and second switches and by closing the first and second switches. The second indicator light is illuminated by closing the first switch while the second switch remains open and by opening the first switch while the second switch remain closed.

Apparatus and method for monitoring bale shape in round balers

A breakaway mechanism for a twine wrapping apparatus on a roll baling machine couples a twine dispensing member to a pinion which is in intermeshing engagement with a gear rack. The pinion and the gear rack cooperate to effect pivoting movement of the twine dispensing member. The breakaway mechanism permits the twine dispensing member to be uncoupled from the pinion when a predetermined load is exerted on the twine dispensing member during its pivoting movement.

A twine cutting and clamping apparatus for a roll baling machine includes an arm having one edge which cooperates with a cutting member such as a knife to cut twine therebetween. The arm has another edge which cooperates with a resilient member such as a spring clip to clamp twine therebetween.

Twine cutting and clamping apparatus for a roll baling machine

A twine wrapping apparatus for a roll baling machine includes a shuttle member which carries a gear rack that intermeshes with a pinion connected to a twine dispensing member such as a twine tube. When the shuttle member is moved generally transversely of the roll baling machine, the pinion is rotated by the gear rack resulting in pivoting movement of the twine tube.

Twine wrapping apparatus for a roll baling machine

A twine cut and clamp mechanism for a roll baling machine includes a pair of arms and a pair of intermeshing spur gears connected, respectively, to the arms. A lever is connected to one of the arms to pivot it. The spur gears cause concurrent pivoting of the other arm when the one arm is pivoted by the lever.
