The present invention proposes a cutting machine comprising: a cutting mechanism, a hitch structure able to be raised relative to the ground, a carrier beam connected to said cutting mechanism by means of a first pivot articulation and to said hitch structure by means of a second pivot articulation, an operating member intended to pivot said cutting mechanism from a working position to a transport position, a limiter device intended to limit the pivoting of said cutting mechanism so as to stop it in an intermediate position when said operating member is actuated, and a device intended to automatically render said limiter device inactive when said hitch structure occupies a raised position relative to the ground.
A lift assist bar for a windrow merger lift mechanism comprising an elongate lift bar connected at one end to the lift mechanism using a ball joint and having a bearing structure on the opposite end, a fulcrum pin connected to a lift arm of the mechanism for contact with an intermediate point of the lift bar between the opposing ends, and a bearing pad connected to the windrower chassis wherein said lift assist bar, being positioned by movement of the lift mechanism from a working position of the merger apparatus toward a non-working position such that the bearing structure contacts the bearing pad, causes the merger assembly to be lifted and held in the non-working position thereby reducing stresses on other linkage members of the lift mechanism.
