First Claim
1. An autonomous mobile work system (20) characterized by:
- a frame (24);
a housing (26) connected to said frame (24), wherein said housing (26) has an outer circumference (28) and an open lower portion (30);
a drive wheel (34), wherein said drive wheel (34) is connected to said frame (24);
a rotating blade assembly (36), wherein said rotating blade assembly (36) is connected to said frame (24) within said housing (26) and is configured to cut vegetation, wherein said blade assembly (36) includes a blade assembly axis of rotation (38);
a single motor (40) operably connected to said blade assembly (36), wherein said motor (40) includes a motor output shaft (44), and said motor output shaft (44) includes an output shaft axis of rotation (46); and
a gear box (50) operably connected to said drive wheel (34) and said motor output shaft (44), said gear box (50) comprising a planetary gear set (104), said planetary gear set comprising a ring gear (110) having an outside diameter (124), wherein said ring gear (110) defines a plurality of cavities (120) at said outside diameter (124), and a locking shaft (126) configured to enter a space within one of said plurality of cavities (120) by rotating between an engaged position and a disengaged position; and
wherein said single motor (40) urges rotation of both said rotating blade assembly (36) and said drive wheel (34).

Abstract
An autonomous mobile work system (20) includes a drive wheel (34) that is connected to a frame (24) and a rotating blade assembly (36). The rotating blade assembly (36) includes a blade assembly axis of rotation (38) and is connected to the frame (24) within a housing (26). The mobile work system (20) further includes a single motor (40) operably connected to the blade assembly (36). The motor (50) includes a motor output shaft (44) and the motor output shaft (44) includes an output shaft axis of rotation (46). The mobile work system (20) still further includes a gear box (50) operably connected to the drive wheel (34) and the motor output shaft (44). The single motor (50) urges rotation of both the rotating blade assembly (36) and the drive wheel (34). The gear box (50) can include a planetary gear set (104) including a ring gear (110) defining cavities (120) at its outside diameter (124). A locking shaft (126) can rotate between an engaged position and a disengaged position with one of the cavities (120).
