Abstract
Abstract An apparatus for distributing liquid manure including a mobile spreader tank to contain the liquid manure and adapted to be drawn by a tractor. A frame is supported by the three-point hitch of the tractor, and a series of soil working elements are mounted on the frame and are adapted to penetrate the soil when the frame is lowered. A delivery tube for the liquid manure is positioned behind each soil working element, and a flexible conduit connects each delivery tube with a valve controlled outlet in the tank. The liquid manure is delivered through the conduit system to the delivery tubes by an auger located within the tank, or alternately, by pressurizing the spreader tank.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
246 words
An apparatus for distributing liquid manure beneath the ground surface, comprising a mobile chassis, a tank to contain the liquid manure and mounting on the chassis, said tank having an outlet opening in an end wall thereof, a frame to be connected to a vertically movable hitch of a vehicle and adapted to be raised and lowered in accordance with operation of said hitch, a plurality of soil penetrating members mounted on the frame and adapted to penetrate the soil when the frame is lowered, conduit means for conducting liquid manure from the tank and including a delivery tube mounted immediately behind each soil penetrating member whereby the liquid manure will be discharged below the surface of the soil, an auger assembly including a housing located on the inside of the tank and connected with a outlet therein, said auger assembly also including an auger disposed within the housing and disposed to convey liquid manure through said housing to said outlet, said auger assembly having a length substantially less than the length of the tank, the outer end of the auger extending through said end wall and the inner end of the auger terminating within the interior of the tank, the axis of the outlet being offset from the axis of the auger, and drive means mounted on said end wall of the tank and located on the outside of the tank and operably connected to the outer end of the auger for driving the same.
Claim 2
Independent Claim

Claim 3
Dependent Claim
59 words
The apparatus of claim 1, wherein the housing has a generally cylindrical first section disposed within the tank having an open end to receive the liquid manure, the axis of said cylindrical housing section being off-set from the axis of said outlet, said housing having a second section disposed within the tank connecting the cylindrical section with said outlet.
Claim 4
Dependent Claim
97 words
The apparatus of claim 2, wherein said apparatus includes a mounting plate secured to said end wall of the tank and bordering the outlet therein, said housing being connected to said mounting plate and extending inwardly of the tank, said auger including a shaft having an end projecting outwardly through aligned openings in the end wall of said tank and said mounting plate, said drive means being supported by said mounting plate and connecting to the projecting end of the auger shaft, said apparatus also including bearing means mounted on the plate for journaling the auger shaft.
Claim 5
Dependent Claim
49 words
The apparatus of claim 1, wherein said tank has a second end wall having a second outlet to discharge liquid manure, and said apparatus includes spray means connected to the second outlet for spraying the liquid manure being discharged from said second outlet over the surface of the ground.
Claim 6
Dependent Claim
41 words
The apparatus of claim 4, wherein said spray means is hinged to said second outlet whereby the spray means can be swung to an inoperative position so that the second outlet can be used for filling the tank with liquid manure.
Claim 7
Dependent Claim
29 words
The apparatus of claim 1, wherein said auger includes a shaft which extends through the end wall of the tank, said drive means being operably connected to the shaft.
