Abstract
A mowing machine having a mobile frame, made up of a portion including the mower units and a support frame, which can be coupled by means of a pivotal arm to a prime mover. During operation, the mobile frame is located behind and offset to one side of the prime mover. The pivotal arm carries drive means for driving the mowing machine through the PTO-shaft of the prime mover. The pivotal arm is constructed so that it may pivot over a broad range of angles thereby facilitating turns. To accomodate the construction of the pivotable arm, the drive means may be divided into three sections interconnected by two universal joints.
