Abstract
Abstract A mower conditioner having rotary cutters arranged in pairs, each pair cutting the crops in front thereof and throwing the cut crops rearwardly to a pair of short length, vertically inclined, crushing rollers which in turn discharge the crops against the underside of a deflector by which the crops are fluffed and deposited upon the field.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A mower conditioner apparatus comprising a frame, a pair of rotary cutting means mounted on the forward end of the frame for cutting field borne crops, means associated with cutting means for slinging cut crops from the cutting means rearwardly therefrom, means for rotating said pair of cutting means toward each other on their forward sides and away from each other on their rear sides, a pair of cooperating generally upright crushing rollers mounted on the frame in fore and aft alignment with the pair of rotary cutting means and spaced a substantial distance rearwardly therefrom, and having an intake nip in intercepting relation to the trajectory of cut crops from said cutting means and having a rearward crop discharge trajectory, and a platform extending under the rollers and spaced from and projecting beneath the cutting means and defining a gap beneath the cutting means for accommodating the discharge of foreign material immediately behind the cutting means and below the platform.
Claim 2
Dependent Claim
161 words
A mower conditioner apparatus comprising a frame, a pair of rotary cutting means mounted on the forward end of the frame for cutting field borne crops, means associated with cutting means for slinging cut crops from the cutting means rearwardly therefrom, means for rotating said pair of cutting means toward each other on their forward sides and away from each other on their rear sides, a pair of cooperating generally upright crushing rollers mounted on the frame in fore and aft alignment with the pair of rotary cutting means and spaced a substantial distance rearwardly therefrom, and having an intake nip in intercepting relation to the trajectory of cut crops from said cutting means and having a rearward crop discharge trajectory, and a platform extending under the rollers and spaced from and projecting beneath the cutting means and defining a gap beneath the cutting means for accommodating the discharge of foreign material immediately behind the cutting means and below the platform.
Claim 3
Dependent Claim
50 words
The invention according to claim 1 and said means for slinging the cut crops comprising drums, and the cutting means comprising radial blades on the lower ends of the drums, said drums defining a crop intake therebetween and effective to grasp the material and convey the cut crop material therebetween.
Claim 4
Dependent Claim
30 words
The invention according to claim 1 wherein said cutting means are positioned to cut in a plane convergingly with the ground over which the apparatus operates forwardly of the apparatus.
Claim 5
Dependent Claim
16 words
The invention according to claim 3 and said rollers operating on axes sloping upwardly and forwardly.
Claim 6
Dependent Claim
22 words
The invention according to claim 1 and guide means comprising a pair of plates converging from respective cutting means to said rollers.
Claim 7
Dependent Claim
35 words
The invention according to claim 1 and said platform being disposed below said rollers and inclined upwardly and rearwardly and having a front portion underposed with respect to the rear portions of said cutter means.
Claim 8
Dependent Claim
33 words
The invention according to claim 1 and means for adjusting the inclination of the cutting means relative to the frame for changing the delivery trajectory of the cut crops to the associated rollers.
Claim 9
Dependent Claim
28 words
The invention according to claim 1 and means for conjunctively changing the inclination of the cutting means and rollers with respect to each other and to the ground.
Claim 10
Dependent Claim
79 words
In a mower conditioner having transversely disposed cutting means along its forward edge, hay conditioning means behind the cutting means for receiving cut hay therefrom, each said conditioning means comprising a pair of cooperatively disposed rollers rotatable about generally upright axes, and means for relatively adjusting the rollers of each pair to vary the position of the intake nip and the discharge area thereof whereby the cut crop is adapted to be positioned by controlling the discharge trajectory thereof.
Claim 11
Dependent Claim
79 words
In a mower conditioner having transversely disposed cutting means along its forward edge, hay conditioning means behind the cutting means for receiving cut hay therefrom, each said conditioning means comprising a pair of cooperatively disposed rollers rotatable about generally upright axes, and means for relatively adjusting the rollers of each pair to vary the position of the intake nip and the discharge area thereof whereby the cut crop is adapted to be positioned by controlling the discharge trajectory thereof.
Claim 12
Dependent Claim
39 words
The invention accoRding to claim 9 and said conditioning means arranged in sets comprising two adjacent pairs of rollers, and one of the rollers of each pair selectively positionable about the axis of the other roller of the pair.
