Attachment for Tractors. (open access)

Attachment for Tractors.

Patent for attachments in tractors.

An important and more specific object is the provision in a tractor of a front axle formed n sections pivotally connected, one section being connected by suitable means with the clutch mechanism and the wheels serving as weights whereby when the tractor rears back and the front wheels leave the ground the axle sections will move relatively and exert a pull upon the means connected with the clutch whereby the clutch will be thrown out."
