ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an arrangement for collecting grass clippings from a rear discharge mower. More particularly, the invention is concerned with a grass collector which can be quickly attached to the mower and which is capable of being emptied without disengaging the bag from the mower.
2. Prior Art
There presently are known various attachment arrangements whereby a collector for grass clippings is mounted to a rear discharge mower for receiving the clippings as they exit the mower's housing. Such arrangements include bags suspended from the mower's handle which have an open end secured to cover the rear discharge port of the mower. Others are collector arrangements which are secured to the exterior of the mower's housing adjacent the rear discharge port. A characteristic of such known grass collector arrangements is that when being emptied, it usually is cumbersome to disengage the collector from its clipping-receiving position, empty the collector and then re-secure it in operative position.
SUMMARY OF THE INVENTION
The present invention provides an improved, simplified arrangement for securing a grass collector to a rear discharge mower which permits the collector to be easily emptied and then restored to operative position. More particularly, the mower is provided with rearwardly and upwardly extending members for supporting a frame member to which the collector is attached. The frame ember is pivotally movable relative to the supporting members so as to be able to swing between a closed, clippings-receiving position adjacent the rear discharge port of the mower and an open, displaced position at which clippings are dumped from the collector. A handle is provided whereby the operator can move the collector to the desired position, and a spring retains the collector's position until it is over-ridden by the operator.
