Abstract

See full text

A hydraulic control for an attachment on a work vehicle. Power is provided to the attachment by manually actuating a control that is biased toward a first position. This first position corresponds to a deactuated mode of the attachment. By unlocking a lock mechanism, the control 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 lock mechanism remains unlocked, and the attachment maintains its operation without hand pressure on the control. The release mechanism actuates the lock mechanism when an operator is not on the platform. As a result, the attachment is deactuated. A filter may be utilized to prevent premature actuation of the release mechanism.
