Abstract
Abstract Improved agricultural apparatus is provided which, for example, may be mounted on the back of a truck, or a trailer, and which may be used conveniently and efficiently to mulch, fertilize and seed an area. The apparatus to be described includes a tank containing a slurry of the seed, mulch and fertilizer, and a circulating pump coupled to the tank for circulating the slurry around the system. In addition, a spray dispensing hose is coupled to the circulating line from the pump for receiving a portion of the circulating slurry to be sprayed over the area. A simple means is provided by which fresh water from a reservoir may be pumped into the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
In agricultural apparatus for providing a mixture of mulch, seed, fertilizer, or the like, to a selected area to be cultivated, said apparatus including a tank forming a reservoir for a slurry of the aforementioned mixture and water, and said tank having an inlet at the top thereof and an outlet at the bottom thereof, and further including a pump having an intake and an outlet, pipeline means coupling the outlet of said tank to the inlet of said pump, and further pipeline means coupling the outlet of said pump to the inlet of said tank, the combination of: a make-up pipeline extending into said tank; a further pipeline positioned within said tank; flexible coupling means connecting the inner end of said make-up pipeline to said further pipeline; and control means coupled to said further pipeline to cause the free end thereof selectively to drop into the outlet at the bottom of said tank selectively to couple the intake of said pump to a source of make-up water.
