Abstract

A lawn mower, in particular a reel lawn mower, can include an articulating swing-out arm for supporting a reel assembly. The swing-out arm can include main and secondary members. The main member and the mower can be coupled to a first joint assembly which can define a first axis therethrough and can be operable to provide for rotation of the main member relative to the mower about the first axis. The main and secondary members can be coupled to a second joint assembly which can define a 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 reel assembly. The swing-out arm can be operable to locate the reel assembly in a mowing position underneath the mower and a servicing position outside of the mower.

Claims

1. An articulating swing-out arm for coupling a reel assembly to a lawn mower, the swing-out arm comprising:

a relatively rigid, elongate main member coupled to a first joint assembly proximate a first end of the main member, the first joint assembly being adapted to be coupled the mower, the first joint assembly defining a substantially vertical first axis therethrough and being operable to provide for rotation of the main member relative to the mower about the first axis, the main member being coupled to a second joint assembly proximate a second end of the main member;

a relatively rigid, elongate secondary member coupled to the second joint assembly proximate a first end of the secondary member, the second joint assembly defining a substantially vertical second axis therethrough and being operable to provide for rotation of the secondary member relative to the main member about the second axis,

wherein the secondary member is adapted to be coupled to the reel assembly proximate a second end of the secondary member, and the swing-out arm is operable to locate the reel assembly relative to the mower in at least a mowing position and a servicing position, and

at least one locking mechanism including a receiver and a latch slidingly operable to be inserted into an aperture of the receiver for selectively fixing at least one of the rotation of the main member and the rotation of the secondary member.

6. The swing-out arm of claim 1, further comprising at least one handle to provide for the grip of an operator.

7. The swing-out arm of claim 6, comprising a first handle attached to the main member and a second handle attached to the secondary member.

8. The swing-out arm of claim 1, wherein the main and secondary members include steel tubing.

9. The swing-out arm of claim 1, wherein the main member has a contoured shape adapted to be complementary to the mower.

2. (canceled)

3. The swing-out arm of claim 2, wherein the at least one locking mechanism comprises a first locking mechanism adapted to be coupled between the main member and the mower for selectively fixing the rotation of the main member relative to the mower and a second locking mechanism coupled between the main and secondary members for selectively fixing the rotation of the secondary member relative to the main member.

4. The swing-out arm of claim 3, wherein the first locking mechanism includes a bracket secured to the main member, the bracket having an aperture therein, the first locking mechanism being selectively operable to engage the bracket with a complementary component of the mower to fix the rotation of the main member relative to the mower.

5. The swing-out arm of claim 3, wherein the second locking mechanism includes a latch, a first sleeve secured to the main member, and a second sleeve secured to the secondary member, the second locking mechanism being selectively operable to engage the latch with the first and second sleeves to fix the rotation of the secondary member relative to the main member.

10. A mower comprising:

a frame;

a plurality of wheels rotatably coupled to the frame, the plurality of wheels including at least first and second drive wheels and a steerable wheel, the first and second drive wheels being coupled on transversely opposite sides of the frame proximate a front end of the mower, the steerable wheel being coupled to the frame proximate a back end of the mower;

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;

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 including;

a relatively rigid, elongate main member coupled to a first joint assembly proximate a first end of the main member, the first joint assembly being coupled to the frame, the first joint assembly defining a substantially vertical first axis therethrough and being operable to provide for rotation of the main member relative to the frame about the first axis, the main member being coupled to a second joint assembly proximate a second end of the main member, and

a relatively rigid, elongate secondary member coupled to the second joint assembly proximate a first end of the secondary member, the second joint assembly defining a substantially vertical second axis therethrough and being operable to provide for rotation of the secondary member relative to the main member about the second axis, the secondary member being coupled to the first reel assembly proximate a second end of secondary member,

wherein the swing-out arm is operable to locate the first reel assembly in at least a mowing position and a servicing position, the mowing position being underneath the frame, longitudinally between the drive wheels and the steerable wheel, and transversely between the drive wheels, the servicing position being outside of the frame.

11. The swing-out arm of claim 10, further comprising at least one locking mechanism for selectively fixing at least one of the rotation of the main member relative to the frame and the rotation of the secondary member relative to the main member.

12. The swing-out arm of claim 11, comprising a first locking mechanism coupled between the main member and the mower for selectively fixing the rotation of the main member relative to the mower and a second locking mechanism coupled between the main and secondary members for selectively fixing the rotation of the secondary member relative to the main member.

13. The swing-out arm of claim 12, wherein the first locking mechanism includes a bracket secured to the main member and a shaft secured to the frame, the bracket having an aperture therein adapted to received the shaft, the first locking mechanism further including a pin selectively operable to engage the shaft and bracket to fix the rotation of the main member relative to the mower.

14. The mower of claim 10, further comprising second and third reel assemblies coupled adjacent one another to the frame proximate the front end of the mower.

15. The mower of claim 14, wherein the mowing position of the first reel assembly is longitudinally rearward of the second and third reel assemblies and transversely between the second and third reel assemblies.

16. The mower of claim 10, wherein the main member of the swing-out arm is complementarily contoured with respect to the back end of the mower.

17. The mower of claim 10, wherein the first reel assembly includes a reel deck for performing cutting operations and a lift arm for vertically positioning the reel deck in coordination with the cutting operations.
