Abstract
A pick-up lift assembly for raising the pick-up for a hay baler to a transport position or lowering the pick-up to a working position and for holding the pick-up in the desired position. The lift assembly includes a lift arm with a series of notches pivotally attached to the pick-up and retained on the side of the bale chamber by guides. The lift arm is raised by a rope which is pulled by a drive shaft that forms a capstan drive. A lift latch engages the notches in the lift arm to hold the pick-up in the desired position. An overcenter coil spring is connected to bias the lift latch into or out of engagement with the notches. Upon raising the pick-up with the rope from the transport position, a first cam on the lift arm contacts a first cam surface on the upper portion of the lift latch and cams the latch until the coil spring is moved past center and biases the lift latch away from the notches. The pick-up and lift arm can then be lowered until a second cam contacts a second cam surface on the lift latch and cams the latch until the coil spring is moved past center and biases the lift latch toward the notches. The lift latch then engages one of the notches preventing further lowering of the lift arm and holding the pick-up in a working position. The second cam is adjustable relative to the notches to adjust the working position. The lift arm is attached to the pick-up by a linkage assembly which includes a lost motion connection and a spring which assist the pick-up to float up over obstructions.
