1. Field of the Invention
The invention relates to an attachment which is mounted on a rotary lawn mower for cleaning the underside of the mower and, more particularly to a quick disconnect attachment which is combatable with garden hose connections.
2. Description of the Prior Art
There is a problem in the prior art in obtaining a suitable means for cleaning the underside of lawn mowers.
In reviewing the prior art patents in this area, it is seen that U.S. Pat. No. 2,936,563 discloses a rotary lawn mower having a water conduit connected through the mower housing. The conduit portion external to the housing is connectable to a hose and the tubular pipe section conduit internal to the housing extends within the housing some distance above the blade. The problems with this attachment are that the tubular pipe conduit internal of the housing extends internally such a distance that it tends to catch grass a debris and itself has to be cleaned, and also is in such close proximity to the blade that there is always the possibility of being hit by the rotating blade which could result in extensive damage. A further problem is that the conduit pipe portion external to the housing requires a complicated system of attaching the hose which requires time and effort.
U.S. Pat. Nos. 3,214,893 and 3,040,990 are also directed to washer attachments for rotary lawn mowers but also have problems associated with complicated attachment elements.
A point of particular interest in this situation is in general use today are quick disconnect attachments for water hoses and other water supply equipment. These devices are popular because of their simplicity of connection and disconnection and their efficiency of use. However, the devices are not compatible with present day lawn mower cleaning attachments because of the lack of a quick connect receiver to connect the same to lawn mowers. It would be a significant improvement in the field if such quick disconnect attachments could be used with a lawn mower cleaning device.
Thus a need exists for an attachment for rotary lawn mowers which efficiently cleans the interior surface of the mower, is inexpensive, is easy to install, is easily attachable to, and easily disconnectable from, hose quick disconnect attachments, does not create an internal cleaning problem because of grass or debris being caught therein, is durable and rust resistant, and is not located in such close proximity so as to come in contact with the blade of the mower.
