Abstract
Abstract A mounting structure for attaching an elongated swather head to a tractor of the bi-directional type, the structure mounting the head in front of the tractor in a swathing direction of travel and accommodating swinging movement of the head to a trailing transport mode behind the tractor when travelling in a direction opposite to the swathing direction. The mounting structure is carried by the tractor which, in the operational mode of the swather, is disposed to one side of the center-line of the swather head. The mounting structure includes members for securement to the tractor and an elongated support member projecting transversely across the front of the tractor to the side of the tractor opposite to the center-line of the swather head. The head has a rear frame member which extends parallel to the head behind an intermediate portion thereof and is carried at one end by a hinge connection to the support member at the side of the tractor opposite to the center-line of the swather head. The hinge connection permits pivoting of the frame member of the swather head about a substantially vertical axis for accommodating the swinging movement of the swather head to a trailing transport mode. A lock is associated with the frame and support members for selectively holding the frame member against the swinging movement when used in the swathing operation.

Claim 3
Dependent Claim
61 words
A structure as defined in claim 1, wherein said means for securement of said tractor mounted frame portion includes a pair of rearwardly projecting members forming a U-shaped portion with said transverse extending support member, said rearwardly extending members being spaced to be disposed on opposite sides of the body of said tractor and including means for attachment to said tractor.
Claim 4
Dependent Claim
58 words
A structure as defined in claim 1, wherein said wheel means has a vertical shaft mounted on said rear frame member for turning about said vertical axis, a crank arm being affixed to said shaft, and wherein said power steer means includes an expandible and contractible hydraulic cylinder connected between said rear frame member and said crank arm.
Claim 5
Dependent Claim
