Abstract
Abstract A machine for handling large crop masses and the like is presented which permits completely automatic processing of these masses and requires only a single operator to effectively manipulate the machine to perform this function. A tiltable bed having a fore-and-aft conveyor is arranged behind a bank of shredding rolls for engaging ground-supported crop masses, loading the latter to a horizontally support position and then feeding the same horizontally into the rolls. Swingable structure is provided between the rolls and the bed for positive feeding of remnant portions of the masses presented at the end of the feeding cycle. The bed and the processor are releasably connected such that they effectively cooperate as a single machine, yet at the same time may be used individually to perform other unrelated farm tasks.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
119 words
A method of reducing a large mass of crop material including the steps of: engaging an upstanding crop mass from beneath the latter with a horizontally moving conveying force to advance the mass in the direction of movement of said conveying force; continuing said advancement of the mass using said conveying force only as the mass is progressively delivered into the mechanism for shredding the same; passing said mass over a standby source of swingable lifting force on the way to said mechanism; and after shredding most of the original mass using said conveying force only, restraining the remaining portion of the upstanding mass against tipover and feeding the same into the mechanism using said swingable lifting force only.
Claim 2
Independent Claim
119 words
A method of reducing a large mass of crop material including the steps of: engaging an upstanding crop mass from beneath the latter with a horizontally moving conveying force to advance the mass in the direction of movement of said conveying force; continuing said advancement of the mass using said conveying force only as the mass is progressively delivered into the mechanism for shredding the same; passing said mass over a standby source of swingable lifting force on the way to said mechanism; and after shredding most of the original mass using said conveying force only, restraining the remaining portion of the upstanding mass against tipover and feeding the same into the mechanism using said swingable lifting force only.
Claim 3
Dependent Claim
33 words
A method as claimed in claim 1, wherein all of the said steps are carried out while the mass is being transported and the shredded material is being discharged in a continuous stream.
Claim 4
Dependent Claim
221 words
A machine for handling large crop masses including: an elongate, horizontally disposed flat bed adapted to carry said crop masses; an upright crop processor adjacent one end of the bed for progressively shredding a mass of crop material presented thereto, said bed having a plurality of laterally spaced, load-supporting rails extending between the opposite ends of the bed; an endless conveying element looped longitudinally around each of said rails, respectively, each element presenting an upper working stretch movable toward said processor from the opposite end of the bed in unison with corresponding stretches of the other elements for the purpose of delivering a mass along the rails into the processor; and a lift at said one end of the bed held against longitudinal displacement relative to the latter during operation in disposition for a mass to pass over the same during its delivery by said elements to the processor, said lift including a plurality of longitudinally extending tines interdigitated between said rails and said elements in a manner to avoid interference with a mass moving along said beams above the tines, said lift further including means for selectively operating said tines to swing the same in unison from said interdigitated position to a raised, feeding position for lifting a final portion of the mass off the bed and into the processor.
Claim 5
Dependent Claim
221 words
A machine for handling large crop masses including: an elongate, horizontally disposed flat bed adapted to carry said crop masses; an upright crop processor adjacent one end of the bed for progressively shredding a mass of crop material presented thereto, said bed having a plurality of laterally spaced, load-supporting rails extending between the opposite ends of the bed; an endless conveying element looped longitudinally around each of said rails, respectively, each element presenting an upper working stretch movable toward said processor from the opposite end of the bed in unison with corresponding stretches of the other elements for the purpose of delivering a mass along the rails into the processor; and a lift at said one end of the bed held against longitudinal displacement relative to the latter during operation in disposition for a mass to pass over the same during its delivery by said elements to the processor, said lift including a plurality of longitudinally extending tines interdigitated between said rails and said elements in a manner to avoid interference with a mass moving along said beams above the tines, said lift further including means for selectively operating said tines to swing the same in unison from said interdigitated position to a raised, feeding position for lifting a final portion of the mass off the bed and into the processor.
Claim 6
Dependent Claim
27 words
A machine for handling large crop masses as claimed in claim 3, wherein said bed, processor and lift are carried by a mobile frame having ground-engaging wheels.
Claim 7
Dependent Claim
50 words
A machine for handling large crop masses as claimed in claim 4, wherein said bed is tiltable about a horizontal transverse axis between a normally horizontal position and a loading position wherein the other end of said bed is adjacent the ground for loading ground-supported crop masses onto the bed.
Claim 8
Dependent Claim
37 words
A machine for handling large crop masses as claimed in claim 5, wherein said bed has a crawler unit adjacent said other end, disposed to engage the ground when the bed is tilted to its loading position.

A machine for handling large crop masses as claimed in claim 3, wherein said processor includes lateral transport means for discharging shredded crop from the machine.
Claim 10
Dependent Claim
159 words
In a machine for handling large masses of crop material, the combination comprising: a mobile crop processor including a bank of shredding rolls; a mover having a normally horizontal, tiltable bed for loading and transporting a crop mass and a conveyor on said bed; and means detachably coupling said processor and said mover in tandem and in such a relationship that one end of said conveyor is disposed adjacent said bank for delivering crop material supported on said bed to said processor, said processor and said mover each being provided with a pair of ground-engaging wheels rotatable about respective transverse axes, said mover being disposed behind said processor and having an elongate, forwardly extending tongue, said coupling means securing said tongue to said processor frame forwardly of said wheels, one of said pairs of wheels being disposed inboard of the other pair, said inboard pair of wheels being partially disposed within the space between said other pair of wheels.
