Abstract
Abstract A removable field silage chopper in which the chopper is removably connected to the front of a tractor with a steering link between the steerable wheels of the tractor and the steerable wheels of the chopper to provide for movement of the chopper and tractor in unison. The power is supplied to the chopper components from a demountable shaft connected through gearing to the power take-off of the tractor. Similarly, the chopper is pivotally mounted on the front of the tractor so that it may be raised or lowered between working and transport positions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
242 words
The removable field silage chopper comprising; a stalk gathering and severing mechanism mounted on a steerable wheeled support; a rotatable chopper means positioned in receiving relationship with the severing mechanism and adapted to chop stalk material into small pieces; auger means mounted on the wheeled support adjacent the chopper means and adapted to move the chopped pieces of stalk material parallel to the axis of cutting and to one side of the chopper means; blower means positioned on the wheeled support adjacent the auger means in material receiving relationship therewith and adapted to receive and discharge stalk material pieces from the chopper; connecting arm means mounted on the steerable wheeled support and adapted to be connected to the tractor near the front end of a tractor frame, tie rod linkage means connected to a tie rod of the wheels of the steerable wheeled support and adapted to be connected to the front steerable tractor wheels to cause the steerable wheels of the support to be steered with the front tractor wheels; power transmitting means connected to the gathering and severing means, the chopper means, auger means and blower means and driven from a single input shaft; and a demountable shaft means connected to the input shaft of the power transmitting means on the wheeled support and adapted to extend along the side of a tractor from the silage chopper to connect to a power takeoff of the tractor to be driven thereby.
Claim 2
Dependent Claim
242 words
The removable field silage chopper comprising; a stalk gathering and severing mechanism mounted on a steerable wheeled support; a rotatable chopper means positioned in receiving relationship with the severing mechanism and adapted to chop stalk material into small pieces; auger means mounted on the wheeled support adjacent the chopper means and adapted to move the chopped pieces of stalk material parallel to the axis of cutting and to one side of the chopper means; blower means positioned on the wheeled support adjacent the auger means in material receiving relationship therewith and adapted to receive and discharge stalk material pieces from the chopper; connecting arm means mounted on the steerable wheeled support and adapted to be connected to the tractor near the front end of a tractor frame, tie rod linkage means connected to a tie rod of the wheels of the steerable wheeled support and adapted to be connected to the front steerable tractor wheels to cause the steerable wheels of the support to be steered with the front tractor wheels; power transmitting means connected to the gathering and severing means, the chopper means, auger means and blower means and driven from a single input shaft; and a demountable shaft means connected to the input shaft of the power transmitting means on the wheeled support and adapted to extend along the side of a tractor from the silage chopper to connect to a power takeoff of the tractor to be driven thereby.
Claim 3
Dependent Claim
38 words

Claim 4
Dependent Claim
29 words
The field silage chopper of claim 1 and including means connected between the tractor and the wheel support to elevate and lower the stalk gathering and severing mechanism thereof.
Claim 5
Dependent Claim
20 words
The field silage chopper of claim 1 in which the demountable shaft means includes slidable couplings and universal couplings therein.
Claim 6
Dependent Claim
55 words
The field silage chopper of claim 1 in which the auger means includes a pair of augers mounted on an axis parallel to the axis of the chopper means and parallel to the axis of the blower means with the blower means positioned to one side of and adjacent the augers and the chopper means.
Claim 7
Dependent Claim
29 words
The field silage chopper of claim 5 in which the augers are journaled and supported at one extremity only providing a cantilever type mounting remote from the blower means.
Claim 8
Dependent Claim
47 words
The field silage chopper of claim 1 in which the power transmitting means includes a gear reduction means connected to the input shaft thereof and providing a plurality of output shafts connected respectively to the staLk gathering and severing means, chopper means, auger means and blower means.
Claim 9
Dependent Claim
66 words
The field silage chopper of claim 3 in which the means connected between the tractor and the wheeled support includes an actuator adapted to pivot the wheeled support on its wheels relative to the tractor for lowering and elevating the stalk gathering portion thereof between working and transport position with said actuator being adapted to be connected to a source of hydraulic power on the tractor.
Claim 10
Dependent Claim
38 words
The field silage chopper of claim 1 in which the tie rod linkage means includes flange means connected to one of the wheels on the steerable wheeled support and on the tractor with a removable linkage connected therebetween.
Claim 11
Dependent Claim
48 words
The field silage chopper of claim 1 in which the connecting arm means includes pivoted arm members pivotally mounted on the wheeled support with connecting means at the free extremity of the same adapted to be connected to a U-shaped frame attached to the chassis of the tractor.
Claim 12
Dependent Claim
197 words
A field silage chopper adapted to be removably mounted to the front of a tractor comprising: a steerable wheeled support, stalk gathering, severing and chopping means mounted in cooperative relationship to each other and to said support, transferring means mounted to said support for receiving and conveying the chopped stalk from said support to a point remote therefrom, connecting arm means mounted on the steerable wheeled support and adapted to be connected to the tractor near the front end of a tractor frame, tie rod linkage means connected to a tie rod of the wheels of the steerable wheeled support and adapted to be connected to the front steerable tractor wheel assembly to cause the steerable wheels of the support to be steered with the front tractor wheels; power transmitting means connected to the gathering and severing means, the chopper means and transferring means and driven from a single input shaft; and a demountable shaft means connected to the input shaft of the power transmitting means on the wheeled support and adapted to extend along the side of a tractor from the silage chopper to connect to a power take-off of the tractor to be driven thereby.
Claim 13
Dependent Claim
197 words
A field silage chopper adapted to be removably mounted to the front of a tractor comprising: a steerable wheeled support, stalk gathering, severing and chopping means mounted in cooperative relationship to each other and to said support, transferring means mounted to said support for receiving and conveying the chopped stalk from said support to a point remote therefrom, connecting arm means mounted on the steerable wheeled support and adapted to be connected to the tractor near the front end of a tractor frame, tie rod linkage means connected to a tie rod of the wheels of the steerable wheeled support and adapted to be connected to the front steerable tractor wheel assembly to cause the steerable wheels of the support to be steered with the front tractor wheels; power transmitting means connected to the gathering and severing means, the chopper means and transferring means and driven from a single input shaft; and a demountable shaft means connected to the input shaft of the power transmitting means on the wheeled support and adapted to extend along the side of a tractor from the silage chopper to connect to a power take-off of the tractor to be driven thereby.
