3. Third is Active Protection System consisting of two separate powerful springs that apply pressure to the hooks.

What happens if hydraulics fail? In an event of the hydraulic failing, the bucket stays on both pins through the safety systems, however, the bucket will have some movement on the pins to provide indication of failure to the operator.

Detach Sequence? Yes. The Smart Valve system does not allow the bucket to detached unless in the fully crowded in position.

What is a Smart Valve? A Smart Valve is a simple float device that prevents Hydraulic Oil from flowing to the cylinder unless the hitch is in the fully crowded in position.

Can the bucket become detached whilst digging? No. The operator must intentionally go through the re-lease sequence within the permitted release zone.
