Abstract: A mowing arrangement includes a main, mobile frame to which a base or first carrier part or frame is mounted for being pivoted vertically by a remotely operable hydraulic motor. Mounted to the base carrier frame is a second carrier part to which arms supporting opposite side and front mowing units are attached. The front-mounted mowing unit is mounted to the second carrier part through the agency of a fourth carrier part, in the form of a parallelogram linkage that includes the support arm for the front-mounted mowing unit. The second carrier part is mounted for pivoting about a transverse, horizontal axis so that the cutting angles of each of the mowing heads can be remotely adjusted by pivoting the second carrier part. A third carrier part is fixed for movement with the second carrier part and supports a drive transmission having output shafts respectively coupled for supplying power to the three mowing heads.

Abstract: A mowing arrangement includes three mowing units with which are associated a drive system including transmissions associated with each unit that are alike to the extent that the mowing units may be easily exchanged with one another. Specifically, one of the mowing units has an angle drive transmission while the transmissions on the other two mowing units are belt or chain drive transmissions. All transmissions are mounted for easy replacement whereby the angle drive transmission may be replaced by a belt or chain drive transmission like the other mowing units if it is desired to use the front mowing unit as a side mowing unit. A drive system variant includes two angle gear boxes used as a power-receiving transmission, with the result that all of the mowing units can be constructed exactly the same.
