Lawn mower with transport lock

摘要

A transport lock assembly for the mower deck of a lawn mower automatically engages when the deck is lifted to a clearance height. The transport lock assembly includes a transport lock that is biased into a locking position by a biasing member. The transport lock engages a surface of a deck prop that is also used in the lawn mower's height-of-cut assembly. The transport lock assembly includes a transport lock actuator that is used to disengage the transport lock, and also includes a transport lock disabling mechanism that prevents the transport lock from automatically engaging.

主权项

1. A lawn mower comprising:
a frame; a prime mover supported by the frame; a mower deck; a cutting blade mounted below the mower deck to cut vegetation under the mower deck; a deck lifting assembly for raising and lowering the mower deck with respect to the frame; a deck prop interconnected with the mower deck and movable with the mower deck; a transport lock movable between a locking position and a non-locking position; a biasing member biasing the transport lock toward the locking position; and a transport lock actuator interconnected with the transport lock and movable into a first position in which the transport lock actuator moves the transport lock into the non-locking position against the biasing force of the biasing member; and a transport lock disabling mechanism for holding the transport lock in the non-locking position against the biasing force of the biasing member, the transport lock disabling mechanism including a projection mounted to the frame, the projection selectively engaging the transport lock actuator to hold the transport lock actuator in the first position; wherein the transport lock abuts a first surface of the deck prop to hold the transport lock in the non-locking position; wherein the transport lock moves into the locking position under the influence of the biasing member upon the mower deck achieving a clearance position; and wherein the transport lock in the locking position engages a second surface of the deck prop to retain the mower deck in a locked position.
