PICKUP ATT~CHMENT FOR HARVEST[NG MACHINES
_ CKGROUND OF THE IMVENTION
This invention relates generally to pickup attachments llsed on crop harvesting machines.
A typical pickup attachment includes a reel consisting of a plurality of fingers rotatable in a predetermined path in order to engage and pick up crop material from the ground. It is important ~or the path of these fingers to follow the contour of the ground in proximity thereto during operation so that a very high percentage of the crop material is picked up.
One conventional type of pickup attach~ent has been supported by what is commonly referred to as gauge wheels at the sides of the attachment. These yuage wheels are mounted on arms which extend orward of the pickup reel. This type of pickup attachment has a drawback when operated over rough or uneven terrain, in that the guage wheels tend to lift the reel upward to an extent where the path of the fingers i~ not in prQximity to the ground and thus the fingers fail to pick up some of the crop material.
Another conventional type of pickup atta~hment has been supported by what is commonly referred to as shoes or skids undernea~h the attachment. These shoes or skid~ slide alonq the surface of the ground during operation. When operated over rough or uneven terrain, this type of pickup attachment has a drawback in that the shoes tend to plow or di~
into the ground. A method that i~ 30metimes used to avoid thi~
drawback i5 to lift the entire reel upward when traversin~ a rough or uneven ar~a of ground. However, this is unacceptable since a considerable amount of crop material may not be picked up. The shoes also ~ay clamage new plant growth on any kind o~
terrain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 and 2, the pickup attachment 10 according to the present invention includes a frame 12 supporting a reel 14 which has a series of projecting fingers 16 located between stripper plates 18. These fingers 16 are connected to a central shaft 20 for rotation to engage and pick up crop material. The frame 12 also preferably supports an auger 22 located above and behind the reel 14. The auger 22 receives crop material from the fingers 16 and the flightin~ 24 thereof consolidates the crop material toward the center of t`ne pickup attachment 10 so that it can be fed into a crop harvesting machine such as a forage harvester 26. A con~entional windguard 28 is mounted on the frame 12 to hold crop material down on the reel 14.
The pickup attachment 10 is attached to the forage harvester 26 by pivot connections 30, and rotary driving power is delivered from tne forage harvester 26 by conventional means tQ a drive shaft 32 on the pickup attachment 10. The drive shaft 32 ther-rotates the auger 22 and the fingers 16 of the reel 14 in kno~n manner via the chains 34 and 36, respectively. As seen in Figs. 3 and 4, the fingers 16 are rotated about the axis 21 of the central shaft 20 in a predetermined path 3~.
The left-hand side 10a of the pickup attachment 10 (as viewed fro~ behind the forage harveste~r 26 loo~ing in the dlrection of normal travel T) is supported by a gauge wheel assembly 40 ~hich ~0 1 includes a wheel 42 carried by a pair of arm~ 44. Bolts 46 and 48 are used to fasten the arms 44 to the frame 12. The arms 44 each have a slot 50 shown in Fig. 3 for receiving the bolt 48 to permit pivotal adjustment of the wheel 42 about the bolt 46 when both bolts 46 2nd 48 are loosened. ~he slots 50 are arranged and dimensioned so that the wheel 42 is only permitted to be disposed in posi~ions where its center 43 is substantially in alignment vertically with the axis 21 of the reel central shaft 20. In the preferred embodiment, the wheel 42 is adjustable in a range where its center 43 is between one inch ahead of and one inch t~ehind the reel central shaft axis 21.
The right-hand side lOb of the picliup attachment 10 (as viewed from behind the forage harvester 26 looking in the direction of normal travel T~, is supported by a roller assembly 52 that includes a roller 54, preferably formed of rubber material, carried by a pair of arms 56. Bolts 533 and 60 are used to fasten the ar~;s 56 to brackets 62 underneath the frame 12. Each bracket 62 includes a guide slot 64 for receiving the bolts 58 and a series of positioning holes 66 for receiving the bolts 60 to permit substantially vertical linear adjustment of the roller 54. The slots 64 and the holes 66 are arranged so that the roller 54 is positioned wi~h its center 53 located ~ehind the axis 21 of the reel central shaft 20 and behind t~,e center 43 of the wheel 42. The outer surface 55 o~ the roller 54 i5 spaced from the path 38 of the fingers 16. Preferably7 the roller 54 is linearly adjustable on a slight inoline with respect to vertical in order to maintain substantially the same spacing between the outer surface 5S of th~
roller 54 and the p~th 38 of the Eingers 16.
An extensible jack les 68 is moun~ed on the frame 1~ to support the rear of the pickup attachmert 10 wllen it is disconnected from the forage harvester 26.
The above-desoribed arrangement of the wheel 4? and the roller 54 allows the path 3~3 of the firgers 16 to ollow the contour of the ground in proximity thereto when oiperated over rough or uneven terrain. A ~urther advantage of this ~rrange3nent of the wheel 42 and the roller 54 is that the left end 23 o~ the auger ~2, as seen in Figs. 1 and 2, is o~en so tt3t ~ windrow of cro~ materi31 whioh is actually wider thar the reel 1~ ma~ be picked up.
An i~portant aspect oE the present invention is that the roller 54 is located unde3neath the pickup attae)l3nent 10 in a 7(~
1 position which provides a cantilevered end portion 15 (best shown in Fig. 2) on the reel 14 which is very useful when operating the pickup attachment 10 with its right-hand s.ide lOb close to an obstacle such as a fence or a ridge along the side of a field.
The foregoing description illustrates preferred embodiments of the invention. However, concepts employed may, based upon such description, be employed in other embodiments without departing from the scope of the invention. Accordingly, the following claims are intended to protect the invention broadly, as well as in the specific forms shown herein.
