Abstract
A medium sized spraying system quickly and easily mountable on a small sized tractor having an auxiliary power take off at or near the front of the tractor. A fluid pump is mountable near the front power take off and utilizes the power of a front power take off to produce pumping action. Fluid conduits are directed to the rear of the tractor where a support framework is releasably connected to the rear of the tractor. The support frame holds a substantially sized fluid tank and a spraying boom.
Claims8
A spraying system for attachment to a lawn and garden size tractor having a rotating auxiliary drive means near the front of the tractor, a front connection means at the front of the tractor, and a rear connection means at the rear of the tractor, comprising:
- mounting means connectable to the front connection means for holding a mechanically-powered fluid pump means to allow operative connection of the fluid pump means to the auxiliary drive means, the front connection means including aperture in the front of the tractor, the mounting means including a bar insertable into said apertures and being releasably securable by locking means;
- frame means for supporting a spraying tank and spraying boom;
- attachment means for attaching the frame means to the rear connection means at the rear of the tractor, the rear connection means including pins extending from positions generally at the rear of the tractor, the attachment means comprising a quick attach means including bracket means having generally vertical slots which can be inserted over said pins, and having quick release means to lock the frame means to the rear of the tractor and in a generally horizontal position, said quick release means being spaced from said pins, the vertical slots and the pins allowing the frame means to be pivoted on the pins so that one end of the frame means which includes the quick attach means can be lifted and connected to the pins, and the opposite end then pivoted up to horizontal and the frame means locked into position with the quick release means;
- and
- fluid connection means for fluidly communicating between the mounting means at the front of the tractor and the frame means at the rear of the tractor to allow pumping action with respect to the contents of the spraying track and the spraying boom, the fluid pump means being mechanically driven by the auxiliary drive means at the front of the tractor, but delivering pumping action to the boom and tank at the rear of the tractor.
A spraying means for enabling a relatively small lawn and garden size tractor having a front end, rear end, and an auxiliary drive pulley generally near the front end of the tractor to produce efficient, controllable, and reliable spraying pressure for a substantially-sized liquid holding tank and spraying mechanism comprising:
- a support frame having a front, a rear and opposite sides, and including a first mounting means for holding and supporting a tank of at least several gallon capacity, second mounting means for holding and positioning a spraying mechanism, and attachment means at the front of the support frame for releasably attaching the support frame to the rear end of the tractor, the attachment means for releasably attaching the support frame to the tractor including pins, at least some of which are spring loaded, for quick and easy mating into apertures positioned in the rear of the tractor;
- the support frame extending rearwardly from the tractor when attached, the sides of the frame being generally no wider than the tractor;
- a pump mount including support means for securement of a fluid pump means, connection means for releasable attachment of the pump mount means at generally the front of the tractor, and the transfer means for transferring mechanical power from the auxiliary drive pulley to a pump pulley which can be operatively connected to the fluid pump means, the connection means for releasable attachment at the front of the tractor for the pump mount means including a bar insertable into apertures in the front of the tractor, and being releasably securable in that position by a locking means;
- and
- fluid conduits connectable between the pump mount means, the tank, and the spraying mechanism to provide a pumping network powered by the auxiliary drive pulley and the fluid pump means at the front of the tractor and delivering pumping action to the tank and spraying mechanism at the very rear of the tractor, the size of the auxiliary drive pulley and pump pulley at least partially determining the pressure produced by the spraying means.
