Removal (Fig. 103)
1. Park machine on a level surface, lower cutting units,
stop engine, apply parking brake and remove key from

supply by separating the cutting unit power disconnect
couplers (see Opening Electrical Circuit to Cutting Units
in the General Information section of this chapter). This
