In the drawings the relatively stationary frame It will be noted that the bolt and plate assemof the farm machine is indicated by the numeral bly is such as to allow the seat, which is at- 55 upper plate, a rod having itsupper end connected tached to the plate H, to have the necessary side and forward play. It is desired to prevent unusual rear shifting since this would tend to unseat the driver. This shifting is governed by making the bolt holes sufliciently large as shown in the drawings, and utilizing the ever important guide pin 20 and its associated collar or socket I8. The shape of the bore [9 will determine, to a large extent, the shifting of the seat. Added to this, however, is the retentive action of the series or pairs of intersecting coiled springs 21 and 28. These are arranged as brought out to advantage in Figure 4 and located around the perimeter of the complete assembly wherethey distribute strain and stress and add to the uniform balance of the structure as a whole.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
