Abstract
A lift link assembly couples a baler needle to a lift arm. The lift link assembly includes a hollow lift link extending along a coupling axis, a lift bar slidably received by the lift link and an adjusting link. An overload protection mechanism includes a block fixed to the lift bar and coupled to the adjusting link, and a plate fixed to an end of the lift link. A pair of clamping bolts clamp the plate to the block. The clamping bolts are in tension and are substantially parallel to the coupling axis.

A lift link assembly for coupling a baler needle to a lift arm, the lift link assembly comprising:
- a lift link extending along a coupling axis, the lift link including a lost motion element;
- and
- an overload protection mechanism comprising:
- a block fixed to a first end of the lost motion element and coupled to a frame of the baler needle;
- a plate fixed to a second end of the lift link;
- and
- a clamping member for clamping the plate and the block together, the clamping member being in tension and having an axis which is substantially parallel to the coupling axis.
