Earth working apparatus
First Claim
1. An earth working apparatus comprising:
- a. a first frame having laterally spaced ground engaging wheels;
b. a second frame mounted on said first frame and selectively movable between a storage position and a working position;
c. means mounted on and extending from one of said first frame and said second frame for connecting same to a prime mover;
d. means mounted on said second frame and movable therewith for cutting vegetation extending above a ground surface;
e. means mounted on said first frame for storage of a supply of gaseous fertilizer;
f. means operatively connected to said gaseous fertilizer storage means and mounted on said second frame and movable therewith for opening a plurality of laterally spaced furrows and introducing gaseous fertilizer into the furrows, said means for opening the furrows including means for closing same after introducing the gaseous fertilizer thereinto; and
g. means mounted on said first frame and operatively connected to said second frame and to a power source of the prime mover for selectively moving said frame between the storage position and the working position, said means for selectively moving said second frame between the storage position and the working position including;

Abstract
An earth working apparatus for use in agricultural pre-planting operations includes a first frame having laterally spaced ground engaging wheels and a second frame having a leading edge thereof pivotally mounted on the first frame adjacent a leading edge thereof and movable between a storage position and a working position. The second frame has a mower thereon for cutting vegetation extending above a ground surface and a first plurality of sweeps for opening a plurality of laterally spaced furrows to receive gaseous fertilizer therein and a second plurality of sweeps to close the furrows after introducing the gaseous fertilizer thereinto. The first plurality of sweeps each have a flow passage thereon for flow of gaseous fertilizer into the respective furrows from a storage and supply tank mounted on the first frame.
