Abstract
Abstract A wheeled fertilizer trailer wherein the tank is mounted within a wheeled frame to present a low profile and lower the center of gravity of the trailer. The frame having a relatively high location relative to growing crops and having very small projections on the bottom thereof, the clearance for crops is higher than conventional fertilizer trailers wherein the tank is mounted on top of the wheeled trailer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A fertilizer trailer, comprising: a frame, a tank attached to said frame with a substantial portion of the tank disposed below the horizontal plane of the frame thereby providing a generally smooth, bottom surface for the trailer, wheel assemblies attached to said frame to support said frame and said tank, said frame including two parallel spaced longitudinal beams, means interconnecting the forward ends of said beams, said frame further including a yoke having an upwardly disposed semicircular midportion and a horizontal portion attached to each end of said midportion, with said beams attached at their other ends to said yoke.
Claim 2
Dependent Claim
100 words
A fertilizer trailer, comprising: a frame, a tank attached to said frame with a substantial portion of the tank disposed below the horizontal plane of the frame thereby providing a generally smooth, bottom surface for the trailer, wheel assemblies attached to said frame to support said frame and said tank, said frame including two parallel spaced longitudinal beams, means interconnecting the forward ends of said beams, said frame further including a yoke having an upwardly disposed semicircular midportion and a horizontal portion attached to each end of said midportion, with said beams attached at their other ends to said yoke.
Claim 3
Dependent Claim
26 words
The device of claim 1 wherein said beams are attached to said yoke at the intersections of the midportion and the horizontal portions of said yoke.
Claim 4
Dependent Claim
23 words
The device of claim 2 wherein said tank is circular in cross section, having the same diameter as said midportion of said yoke.
Claim 5
Dependent Claim
26 words
The device of claim 1 wherein said wheel assemblies further include a pair of wheels each mounted for adjustment along said horizontal portions of said yoke.
Claim 6
Dependent Claim
48 words
The structure as defined in claim 8 wherein said horizontal portions of the yoke are generally in alignment with the center of the tank with the lower periphery of the tank being disposed below the upper periphery of the wheels mounted on said horizontal portions of said yoke.
Claim 7
Dependent Claim
48 words
The structure as defined in claim 1 wherein said wheel assemblies include a single dirigible wheel mounted on said interconnecting means at the forward ends of said beams, the upper peripheral edge of the dirigible wheel being disposed above the lower edge of the periphery of the tank.
Claim 8
Dependent Claim
99 words
A trailer comprising an elongated body having a substantially smooth undersurface, an elongated frame supporting said body, said frame comprising a pair of rigid beams extending longitudinally of the body for a substantial portion of the length thereof, front steerable wheel means supporting said frame adjacent the forward end thereof, rear wheel means supporting said frame adjacent the rear thereof, said body including a substantial portion thereof disposed below the horizontal plane of said beams, means supporting said body from said frame without any substantial projections from the undersurface of the body below the horizontal plane of the beams.
Claim 9
Dependent Claim
99 words
A trailer comprising an elongated body having a substantially smooth undersurface, an elongated frame supporting said body, said frame comprising a pair of rigid beams extending longitudinally of the body for a substantial portion of the length thereof, front steerable wheel means supporting said frame adjacent the forward end thereof, rear wheel means supporting said frame adjacent the rear thereof, said body including a substantial portion thereof disposed below the horizontal plane of said beams, means supporting said body from said frame without any substantial projections from the undersurface of the body below the horizontal plane of the beams.
Claim 10
Dependent Claim
95 words
The structure as defined in claim 7 wherein, said means supporting the body from said frame including a transverse support member extending rigidly between the rear end portions of said beams and through said body with a substantial portion of the body below the support member, the outer ends of said support member supporting said rear wheel means whereby a vertical plane in which the center of gravity of the body lies will be disposed between the rear wheel means when the trailer transverses a laterally inclined surface that is inclined at a substantial angle.
