Abstract
Abstract The bale-forming machine has rolling mechanism that initially tumbles loose crop material forwardly between the mechanism and the ground as the machine advances along a windrow. Thereafter, the rolling material becomes confined off the ground in an elevated forming chamber as additional material is fed into the chamber and as the mechanism rolls the material into a bale. Upon reaching a predetermined size, the bale can be tied and then ejected from the chamber through the raised rear section of the machine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
In a mobile baler of the type having a housing provided with an off-the-ground baling chamber and means associated therewith for making a round bale within the chamber from crop materials presented thereto, the improvement comprising: a crop entrance to the chamber located adjacent a lower portion thereof; a crop pickup having a crop engaging portion thereof located generally below said chamber and behind the front of the housing with respect to the normal direction of travel of the baler for lifting crop materials from the ground and feeding the same up toward said chamber; and an open, non-compressive crop receiving and inflow region extending from said crop-engaging portion of the pickup to the forward extremity of said entrance whereby to substantially prevent compaction of picked up crop materials prior to the same reaching said baling chamber.

Claim 3
Independent Claim
69 words
A method of baling crop materials into a round bale that includes the steps of: picking up crop materials from the field at a point generally underneath a baling chamber while traveling across the field; feeding the picked up materials up into the baling chamber without first compacting the same between a pair of opposed rollers or the like; and rolling the materials into a bale within said chamber.
