ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The present invention relates generally to agricultural implement frames and, more specifically, to a versatile mounting arrangement for the wing fold structure on a multi-section implement.
2) Related Art
Frames for large folding implements such as chisel plows, field cultivators and air seeders include an inner or central main frame with outer wings hinged to the main frame to facilitate folding of the wings for a narrower implement transport width. Typically, fold plates are bolted to a transverse tool supporting beam on the main frame which support one end of the folding cylinder. However, various combinations of row or tool spacings and implement widths necessitate that a large number of support bracket spacings must be accommodated on the beam. Often the plates interfere with a desired spacing. The plates can be made with special cut-outs to make room for the support brackets of the row units or tools, but there are still combinations of row spacings and patterns that will result in the plate interfering with one of the brackets. The special plates can greatly increase the number of parts required and thereby increase the cost of the implement. Wing stop arrangements which provide support for the wings in the transport position often require varying sets of components for different types of implements or for implements of the same type having different main frame widths and often do not provide easy wing transport angle adjustment.
BRIEF SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved wing fold structure mounting arrangement for an implement. It is another object to provide such an arrangement which overcomes most or all of the aforementioned problems.
It is a further object to provide such an improved mounting arrangement for the wing fold structure on an implement, the arrangement facilitating use of a variety of row or tool spacings on implements having different frame widths by reducing or eliminating interference between the mounting arrangement and the brackets or the like which attach the row units or tools to the implement. It is a further object to provide such a structure having simple and inexpensive reversible mounting plates for use with different implements, different implement main frame widths and different tool spacings on the implements.
It is another object to provide an improved mounting arrangement for the wing fold structure on a multi-section implement which includes an adjustable bump stop assembly facilitating use of a single assembly design on implements having different main frame widths and permitting easy adjustment of the wing angle in the transport position.
An implement folding cylinder mount constructed in accordance with the teachings of the present invention includes an auxiliary tube spaced above a transversely extending tube on the main frame to accommodate mounting bolts for the tools or row units. L-shaped plates support the auxiliary tube and can be reversed to change the mounting location on the main frame to avoid interference with the desired tool spacing. The same plates and auxiliary tubes can be used on a number of different implements and with different main frame widths to reduce manufacturing costs and the number of parts that have to be stocked.
The reversible plates can be selectively mounted on the main frame with the plates inside or outside of the fore-and-aft tubes connected to the transversely extending tube, depending on the tool placement on the main frame. Therefore, almost any row or standard spacing can be accommodated in the region under the tube and between the fore-and-aft tubes. A bump stop assembly mounted above the auxiliary tube has adjustable telescoping wing contacts facilitating use of a single assembly design on implements having different main frame widths and permitting easy adjustment of the wing angle in the transport position.
These and other objects, features and advantages of the present invention will become apparent to one skilled in the art upon reading the following detailed description in view of the drawings.
