Abstract
Abstract A crop aerating device comprising a bar with spaced fingers positioned transversely of the side sheets of a windrowing mechanism for intercepting crops discharging from a pair of crop conditioning rolls, the fingers functioning to deflect some of the crops downwardly to form a first swath layer and allowing some of the crops to pass between the fingers while retarding the same so as to drop in a second layer on top of the first, some of the crops passing through passages between the ends of the aerating bar and the windrow side sheets which sheets are contoured at their rear ends to form pans which cause the crop thereon to slide and fold inwardly and form a third layer onto the second layer. A method of forming a swath by a multi-layer confluence of crops is also disclosed.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
100 words
In combination with an ambulatory crop harvesting apparatus comprising crop-conditioning rollers oriented to discharge conditioned crops in a rearwardly directed relatively high velocity stream, crop aerating means having a position for impingement by said stream and comprising a plurality of vertically disposed fingers, said fingers having free lower ends for shedding toward the ground crops impinging against said fingers to form a first layer of a swath therebeneath, said fingers being spaced horizontally across said stream for accommodating passage therebetween of some crops in said stream to fall behind the fingers in another layer upon said first layer of crops.
Claim 2
Dependent Claim
100 words

Claim 9
Dependent Claim
37 words
The invention according to claim 1 and windrow-forming means behind said rollers for receiving said stream of crops, and said crop aerating means having another position displaced from said stream of crops entering into said windrow-forming means.
Claim 10
Dependent Claim
34 words
The invention according to claim 8 and said windrow-forming means comprising a top shield disposed in intercepting relation to said stream and said crop-aerating means disposed adjacent the rear edge of said top shield.
Claim 11
Dependent Claim
21 words
The invention according to claim 1 and said aerating means comprising a bar and said fingers removably mounted on the bar.
Claim 12
Dependent Claim
76 words
In a mower conditioner of the type having windrowing means and a pair of crop-crushing rollers discharging a stream of conditioned crops in an upward and rearward stream into said windrowing means, and aerating means for intercepting said stream and having tines raking through the stream for fluffing the same and direCting a portion of the crops downwardly and accommodating the passage of a substantial portion of the crops therethrough to fall upon the ground therebehind.
Claim 13
Dependent Claim
76 words
In a mower conditioner of the type having windrowing means and a pair of crop-crushing rollers discharging a stream of conditioned crops in an upward and rearward stream into said windrowing means, and aerating means for intercepting said stream and having tines raking through the stream for fluffing the same and direCting a portion of the crops downwardly and accommodating the passage of a substantial portion of the crops therethrough to fall upon the ground therebehind.
Claim 14
Dependent Claim
