Disengagement mechanism for a walk behind mower
First Claim
1. A lawn mower comprising:
- a blade housing;
an engine operably coupled to the blade housing and configured 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 drive system comprising;
a first transmission;
a flexible driving member; and
a disengagement assembly comprising a latching lever, wherein the latching lever is configured to switch the first transmission between a disengaged mode and an engaged mode, and wherein the latching lever is configured to move between a disengaged position corresponding to the disengaged mode and an engaged position corresponding to the engaged mode; and
a remote actuator operably coupled to the flexible driving member, wherein responsive to actuation of the remote actuator, the flexible driving member engages a) the latching lever to move the latching lever to the engaged position to thereby place the first transmission in the engaged mode; and
b) the first transmission to provide drive power from the drive shaft to the first set of wheels.

Abstract
A lawn mower (10) may include a blade housing (20), an engine (30), a mobility assembly (310); and a drive system (300). The engine (30) may be operably coupled to the blade housing (20) and configured to selectively rotate a drive shaft (130). The mobility assembly (310) may include a first set of wheels (40, 42) and be selectively operably coupled to the engine (30) to provide mobility of the lawn mower responsive at least in part to operation of the engine (30). The drive system (300) may include a first transmission (110, 120), a flexible driving member (100), a disengagement assembly (116), and a remote actuator. The a disengagement assembly (116) may include a latching lever (125), where the latching lever (125) is configured to switch the first transmission (110, 120) between a disengaged mode and an engaged mode, and where the latching lever (125) is configured to move between a disengaged position corresponding to the disengaged mode and an engaged position corresponding to the engaged mode. The remote actuator may be operably coupled to the flexible driving member (100), where responsive to actuation of the remote actuator, the flexible driving member (100) engages a) the latching lever (125) to move the latching lever (125) to the engaged position to thereby place the first transmission (110, 120) in the engaged mode; and b) the first transmission (110, 120) to provide drive power from the drive shaft (130) to the first set of wheels (40, 42).
