The present disclosure relates to lawn mowers and, more specifically, to an articulating swing-out arm for coupling a reel assembly to a reel lawn mower.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Lawn mowers, in particular reel lawn mowers, can have a variety of components and configurations. For example, it is known to couple a reel assembly to a reel lawn mower with a swing-out arm. A typical swing-out arm can rotate about a single axis to position a reel assembly. However, the components and configuration of a reel lawn mower can limit the ability of such a swing-out arm to position a reel assembly. Accordingly, it would be desirable to provide an articulating swing-out arm.
The present disclosure provides an articulating swing-out arm for coupling a reel assembly to a lawn mower. The swing-out arm can include a relatively rigid, elongate main member coupled to a first joint assembly proximate a first end of the main member. The first joint assembly can be adapted to be coupled the mower. Furthermore, the first joint assembly can define a substantially vertical first axis therethrough and be operable to provide for rotation of the main member relative to the mower about the first axis. The main member can also be coupled to a second joint assembly proximate a second end of the main member. The swing-out arm can further include a relatively rigid, elongate secondary member coupled to the second joint assembly proximate a first end of the secondary member. The second joint assembly can define a substantially vertical second axis therethrough and can be operable to provide for rotation of the secondary member relative to the main member about the second axis. The secondary member can be adapted to be coupled to the reel assembly proximate a second end of the secondary member, and the swing-out arm can be operable to locate the reel assembly relative to the mower in at least a mowing position and a servicing position.
The present disclosure further provides a mower. The mower can include a frame and a plurality of wheels coupled to the frame. The plurality of wheels can have at least first and second drive wheels and a steerable wheel. The first and second drive wheels can be coupled on transversely opposite sides of the frame proximate a front end of the mower, and the steerable wheel can be coupled to the frame proximate a back end of the mower. The mower can include a power unit supported by the frame and operably coupled to at least one of the first and second drive wheels for facilitating motion of the mower. The mower can further include a first reel assembly operable to perform cutting operations of the mower and an articulating swing-out arm for coupling the first reel assembly to the frame. The swing-out arm can have a relatively rigid, elongate main member coupled to a first joint assembly proximate a first end of the main member. The first joint assembly can be coupled to the frame. Furthermore, the first joint assembly can define a substantially vertical first axis therethrough and can be operable to provide for rotation of the main member relative to the frame about the first axis. The main member can also be coupled to a second joint assembly proximate a second end of the main member. The swing-out arm can further have a relatively rigid, elongate secondary member coupled to the second joint assembly proximate a first end of the secondary member. The second joint assembly can define a substantially vertical second axis therethrough and can be operable to provide for rotation of the secondary member relative to the main member about the second axis. The secondary member can also be coupled to the first reel assembly proximate a second end of secondary member. Additionally, the swing-out arm can be operable to locate the first reel assembly in at least a mowing position and a servicing position. The mowing position can be underneath the frame, longitudinally between the drive wheels and the steerable wheel, and transversely between the drive wheels. The servicing position can be outside of the frame.
