RSM161 with cutting attachment Fix v 1.0

This is the original RSM 161 with adapted rotation for the cutting attachment. The Combine has always stuck on slopes with spinning tires, now the mower is not so far down. Except for this adaptation, everything is like Original Giants RSM. In addition, the cutting unit is in there, but I have rised the working speed to 15 km/h. If this is to fast you can also use the original one from Giants.
