摘要： 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.

摘要： 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.
摘要翻译：割草布置包括三个割草单元，其与驱动系统相关联，驱动系统包括与每个单元相关联的传输，其可以相对于修剪单元彼此容易地交换的程度相同。具体地，其中一个割草机具有角度驱动传动，而另外两个割草机组的变速器是带式或链式传动装置。安装所有变速器以便于更换，如果希望使用前部割草单元作为侧面割草单元，则角度传动传动装置可以像其他割草机构一样由皮带或链条传动装置代替。驱动系统变体包括用作受电变速器的两个角度齿轮箱，结果是所有的割草机构都可以完全相同。
