Abstract

A mower deck is selectively coupled to the front of a propelling vehicle. The deck includes a mowing height adjustment assembly to permit the user to vary the cutting height of the mower deck. The deck is movable about a lift shaft from a generally horizontal use position to an upright storage/servicing position while the deck is coupled with the vehicle. A mowing height adjustment lever of the mowing height adjustment assembly not only provides the user with a way to adjust the cutting height but also cooperates with the remainder of the mowing height adjustment assembly to prevent movement of the deck from the use position to the storage/servicing position. Movement of the mowing height adjustment lever from an upright use position to a collapsed position permits the deck to be moved from the use position to the upright storage/servicing position. A latch plate and a catch cooperate to automatically lock the deck in the storage/servicing position when the deck is rotated thereto.

Claims

1. A mower comprising:

a vehicle having a front and a rear;

a mower deck for selective attachment to the front of the vehicle, wherein the deck is selectively movable between a generally horizontal use position and a generally vertical storage/servicing position when attached to the vehicle; and

means for selectively permitting and prohibiting movement of the deck from the use position to the storage/servicing position, said means including a mowing height adjustment lever, wherein movement of the deck from the use position toward the storage/servicing position is permitted when the mowing height adjustment lever is in a collapsed position,

wherein movement of the deck from the use position toward the storage/servicing position is prevented when the mowing height adjustment lever is in an upright position and wherein movement of the deck from the use position to the storage/servicing position is permitted when the mowing height adjustment lever is in a collapsed position.

2. A mower comprising:

a vehicle having a front and a rear;

a mower deck for selective attachment to the front of the vehicle, wherein the deck is selectively movable between a generally horizontal use position and a generally vertical storage/servicing position when attached to the vehicle; and

means for selectively permitting and prohibiting movement of the deck from the use position to the storage/servicing position, said means including a mowing height adjustment lever, wherein movement of the deck from the use position toward the storage/servicing position is permitted when the mowing height adjustment lever is in a collapsed position,

wherein said means for selectively permitting and prohibiting movement of the deck from the use position to the storage/servicing position further includes a first latching member,

wherein the mowing height adjustment lever is movable between an upright use position and the collapsed position, wherein the first latching member cooperates with the mowing height adjustment lever when the mowing height adjustment lever is in the upright position to prevent movement of the deck from the use position to the storage/servicing position.

3. The mower of claim 2, wherein a portion of the first latching member abuts a portion of the mowing height adjustment lever when the mowing height adjustment lever is in the upright position, wherein movement of the mowing height adjustment lever from the upright position to the collapsed position moves the mowing height adjustment lever out of abutting contact with the first latching member and thereby permits movement of the deck from the use position to the storage/servicing position.

4.
