Attorney Ref.: 1107P023CA04 ABSTRACT A drive system includes a first transmission, a second transmission, an idler pulley, and at least one flexible driving member. The first transmission is operably coupled to a first set of .. wheels to provide drive power to the first set of wheels responsive to engagement of the first transmission. The second transmission is operably coupled to a second set of wheels to provide drive power to the second set of wheels responsive to engagement of the second transmission. The at least one flexible driving member is operably coupled to a remote actuator and a drive shaft of the walk-behind outdoor power equipment device. The idler pulley moves responsive to operation of the remote actuator and, based on such movement, the at least one flexible member switches a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode.

The invention relates to a garden hose (GS) with at least one cover layer. The aim of the invention is to improve the grip of the hose relative to the hand of a user and/or on a connection to a connecting element (SK) via a compression-type fitting (UM, HK). For this purpose, a relief structure (RS) is produced on an outward surface of a cover layer (M21) of the hose (GS). Said relief structure (RS) can substantially improve the haptic impression and/or, when the connection (UM) is tight, bring about an interlocking or at least semi-interlocking engagement of retaining elements (HK) of a connecting element (SK) with the relief structure (RS) and substantially increase the retaining force which prevents the hose end from accidentally slipping off the connecting element (SK).
