All wheel drive, walk behind mower
First Claim
1. A walk behind lawn mower comprising:
- a blade housing;
an engine supported at least in part by the blade housing to selectively rotate a drive shaft;
a mobility assembly selectively operably coupled to the engine to provide mobility of the lawn mower responsive at least in part to operation of the engine, wherein the mobility assembly comprises a first set of wheels and a second set of wheels;
a drive system comprising;
a first transmission operably coupled to the first set of wheels;
a second transmission operably coupled to the second set of wheels; and
a single flexible driving member; and
a remote actuator operably coupled to the drive system,wherein, responsive to operation of the remote actuator, the first transmission rotates or rocks to engage the flexible driving member with the first transmission to switch the lawn mover from a no wheel drive mode to an all wheel drive mode, andwherein, in the all wheel drive mode, the flexible driving member engages the first transmission to provide drive power from the drive shaft to the first set of wheels, and the flexible driving member engages the second transmission to provide drive power from the drive shaft to the second set of wheels.

Abstract
A drive system includes a first transmission, a second transmission 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 at least one flexible member selectively engages one of the first transmission or the second transmission to switch a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode via the remote actuator.
