ABSTRACT OF THE DISCLOSURE A pair of cutter bar-type mowers are rearwardly and laterally offset on a mower frame having steerable wheels for moving the mower between a cutting position offset from the tractor and a transport position dir- ectly behind the tractor. A spring-assisted power cylinder raises and lowers the cutting bar from a ground-engaging cutting position to a position with the cutter bar raised off the ground and then to a position with the cutter bar extending vertically for transport. The spring functions only to assist in raising the cutter bar off the ground by pivoting a frame arm and the pivoting of the cutter bar to the vertical position is by the power cylinder only. A non-binding power take-off drive is provided between the tractor and the mower with universal joints being provided on the tractor power take-off and on the tongue of the mower at equal distances from the pivotal connection of the drawbar and tongue whereby the tractor turned at a 90° angle to the mower causes only a 45° angle between the drive shaft and the tongue and drawbar. Each of the mowers are adapted to break away from hitting an obstruction and the drive shaft from the first mower to the second mower includes a rearwardly extending section connected to a gear box in turn having a laterally extending section which is extendable and is connected to a gear box on the second mower pivotal with the second mower when moving between the cutting and breakaway positions.
