Abstract
Abstract A plurality of fluffer shields mounted in generally end-to-end relationship on the frame of a crop harvester and conditioner. Each fluffer shield is pivotally adjustable independently of the other shields to control the rearward movement of portions of the cut crop delivered rearwardly of the harvesting machine by the crop conditioner rolls of the machine, so as to control the cross-sectional shape and density of a windrow produced by the machine.

Claim 1
Independent Claim
209 words
In a crop harvesting machine including a mobile frame elongated in a direction transversely of the direction of travel of the machine, a mower, and crop conditioner rolls extending longitudinally of said frame, said rolls being operative to deliver cut and conditioned crop rearwardly of the direction of travel of the machine; the improvement comprising, a plurality of cooperating fluffer shields having front and rear edges and disposed in a group extending transversely of the direction of travel of the machine, means pivotally mounting each of said fluffer shields to said frame for swinging movements on a horizontal axis extending transversely of the direction of the machine travel and independently of the others of said fluffer shields, a plurality of support arms at least one for each of said fluffer shields, and a plurality of brackets, one pair for each of said support arms, one bracket of each pair being mounted on said frame and the other on a respective one of said fluffer shields, each of said support arms having one end pivotally secured to one of the brackets of its respective pair and secured at its other end to a selected one of a plurality of spaced points on the other bracker of its respective pair thereof.
Claim 2
Dependent Claim
209 words
In a crop harvesting machine including a mobile frame elongated in a direction transversely of the direction of travel of the machine, a mower, and crop conditioner rolls extending longitudinally of said frame, said rolls being operative to deliver cut and conditioned crop rearwardly of the direction of travel of the machine; the improvement comprising, a plurality of cooperating fluffer shields having front and rear edges and disposed in a group extending transversely of the direction of travel of the machine, means pivotally mounting each of said fluffer shields to said frame for swinging movements on a horizontal axis extending transversely of the direction of the machine travel and independently of the others of said fluffer shields, a plurality of support arms at least one for each of said fluffer shields, and a plurality of brackets, one pair for each of said support arms, one bracket of each pair being mounted on said frame and the other on a respective one of said fluffer shields, each of said support arms having one end pivotally secured to one of the brackets of its respective pair and secured at its other end to a selected one of a plurality of spaced points on the other bracker of its respective pair thereof.
Claim 3
Dependent Claim
80 words
The crop harvesting machine defined in claim 1 in which said support arms have inturned opposite ends, one of the brackets of each pair thereof having an opening for pivotal reception of one of said inturned ends of a respective support arm, the other bracket of each pair thereof having a plurality of openings spaced apart generally in the direction of movement of the machine and each capable of pivotally receiving the opposite inturned end of said respective support arm.
Claim 4
Dependent Claim
