Description:
BACKGROUND OF THE INVENTION 
   This invention relates to grass catchers, and in particular, to grass catcher for a rider lawn motor having a side grass discharge port in the blade housing. 
   Riding lawn mowers are widely used. These mowers are generally used for cutting grass on large lawns, and further for clipping and mulching leaves and other organic material on such lawns. It is desirable to have all of the debris thrown from the outlet of the mowing blade housing such as grass clippings, thatch, and leaves, collected so that they do not fall on the cut lawn. It is, therefore, necessary to provide means to contain the clippings on the mower and easily dispose of the container contents. 
   Various types of containers for collecting debris produced from a riding lawn mower have previously been suggested. Periodically, as the container is filled to capacity, the container must be emptied before equipment operation can continue. In the absence of automatically powered emptying means (which are very expensive and complicated), a user must stop the rider mower, dismount, and manually empty the container, either by physically removing and upending it, or by directly removing the collected load of debris itself. Proper safety precautions demand that the user completely halt operation of the rider mowing equipment and fully deboard prior to carrying out such emptying procedure. 
   The disruptive effect this causes to the user&#39;s efforts to complete the required work and the added physical exertion it requires of him or her are significant. This is especially so given that, where a receptacle container is reduced in size to lessen the weight and volume of its load capacity (so as to minimize the physical exertion required to empty it), the frequency with which the container must be emptied is necessarily increased. Conversely, where the receptacle assembly&#39;s container is increased in capacity to reduce the frequency with which it must be emptied, the container quickly becomes much more cumbersome and difficult to empty. Yet, prompt and regular emptying of the receptacle assembly&#39;s container remains a necessity, lest a clog form in the chuted path through which solid debris is expelled and directed from the vehicular equipment&#39;s working mower deck to the receptacle assembly not only interrupting further equipment operation, but requiring the user to take the necessarily time consuming and inconvenient remedial measures. 
   SUMMARY OF THE INVENTION 
   The rider mower grass catcher of the present invention provides a simple, effective and efficient method of cutting and collecting grass, leaves and other debris in one operation. The present invention provides a side cart mounted directly to one side of a tractor or rider lawn mowing blade housing deck. As grass is cut and expelled out the side of the mower deck, it enters directly into an opening in the side cart. The side cart has a lid which may be opened by the user riding the mower without dismounting. Any side cart entrance pile ups may be easily moved to the side cart rear with a modified straw broom. When the side cart is full, the grass is taken to a central disposable location where it is easily emptied with a snow shovel. In one embodiment of the invention a hard plastic liner is pivotally installed in the side cart. The liner has a long handle attached thereto which permits the user to empty the side cart to the rear of the side cart without using the snow shovel. Fastened to the bottom of the side cart is a galvanized steel sheet which is bent upwards at the front and rear. This allows the side cart to glide over the lawn. Since prior art suction tubes are eliminated, grass can be cut when it is wet and when it is as high as three feet or more. The invention is especially useful on lawns of one half acre and larger. 
   These together with other objects of the invention, along with various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed hereto and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated a preferred embodiment of the invention.
