ABSTRACT:
RELATED APPLICATIONS
There are no previously filed, nor currently any co-pending applications, anywhere in the world.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to lawn equipment and, more particularly, to a rake attachment for a riding lawn mower.
2. Description of the Related Art
Of the many seasonal chores that people perform, the annual raking and disposal of fallen tree leaves is among the most popular and also the most despised. In performing this task, one is required to cover what is often a large area with a rake, collecting the leaves into piles for the disposal thereof. Both physically exerting and time consuming, this process can take several hours, leaving one extremely tired and worn-out. A solution to this task, just starting to find widespread use, is the leaf blower or leaf vacuum. This mechanism, while easier than raking, still requires much time to use, and in addition requires the user to stand for the entire duration.
Accordingly, there is a need for a means by which one can gather leaves into a pile in a quick and effective manner while the user sits down in a comfortable state.
In the related art, there exists some patents for leaf raking devices for attachment to a riding lawn mower as in the instant invention. However, none of them incorporate the forward sweeping side panels for collecting and directing the leaves or the novel leaf raking tines presented here.
A search of the prior art did not disclose any patents that read directly on the claims of the instant invention; however, the following references were considered related:

SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved apparatus to allows for quick clean up of fallen leaves.
It is another object of the present invention to allows a user to sit on a riding mower in relative comfort.
It is yet another object of the present invention to provide a U-shaped leaf rake to gather leaves.
It is yet still another object of the present invention to provide attachment arms to attach the leaf rake in a similar manner to that of snow plows.
It is a feature of the present invention to provide a raising mechanism that allows the leaf rake to be raised while backing up or leveling leaf pile.
Briefly described according to one embodiment of the present invention, the Riding Lawn Mower Leaf Rake, as its name implies, is an apparatus that attaches to the front of a riding lawn mower to aid in the gathering of fallen leaves from lawns, drives, and other similar surfaces. The invention is “U” shaped and is approximately 48 inches wide and 30 inches tall, with the lowest four inches comprising raking tines to gather leaves. The invention attaches to the riding mower by the use of two arms in a manner similar to that which a small snow plow would attach. A mechanism for raising the Riding Lawn Mower Leaf rake is provided as well. The invention functions by pushing leaves into a central pile in much the same manner as a conventional snow plow functions. With the use of the Riding Lawn Mower Leaf Rake, a homeowner or gardener can keep a yard free of leaves in a quick, effortless manner, while sifting on a riding mower in relative comfort.
