Abstract
A lever mechanism (10) suitably, amongst other uses, for use in the control of tractor draft links (22) from a location remote from the tractor operators station. The lever mechanism includes an operating member (40), a support (43) relative to which said operating member is displaceable (Z), a lever (42) pivotally mounted on the support about a pivot axis (44) which is also translationally moveable (X), a first formation (56) on the lever, a second formation (57) on the operating member, and bias means (53) acting to translationally move the lever on its axis (44) away from the second formation (57) to hold the first and second formations (56,57) disengaged when the lever is released. The operating member is displaceable in a given direction (Z) relative to the support (43) by translational movement (X) of the lever (42) on its moveable axis (44) against the bias (53) to bring the first and second formations (56,57) into engagement followed by pivotting (Y) of the lever relative to the support with the first and second formations engaged. When used to control tractor draft links the lever mechanism forms part of the draft link control system and is connected with the remainder of …
