Abstract
Official abstract text for this publication.
A hydraulic control for an attachment on a work vehicle. Power is provided to the attachment by manually actuating a control lever that is biased toward a first position. This first position corresponds to a deactuated mode of the attachment. By unlocking a lock mechanism, the lever may be maintained in a second position under hand pressure. This second position corresponds to an actuated mode of the attachment. The lock mechanism may be actuated by an operator platform-actuated release mechanism. While an operator is on a platform on the vehicle, the loch mechanism remains unlocked, and the lever may be maintained, without hand pressure, in its second position. The release mechanism actuates the lock mechanism when an operator is not on the platform. As a result, the bias of the control lever returns it to its first position, and the attachment is deactuated. A filter may be utilized to prevent premature actuation of the release mechanism.
First claim
Opening claim text (preview).
What is claimed is: 1. A work machine comprising: a chassis; a work attachment disposed on a first end of the chassis; and a work machine control system comprising: a lever movable from a first lever position to a second lever position such that the work attachment is operable when the lever is in the first lever position and the work attachment is not operable when the lever is in the second lever position; a lock configured to hold the lever in the first lever position;…
