I'm speculating here, and getting a little outside of my knowledge, but that won't prevent me from spouting off. I think built up pressure in the hydraulic hoses tend to keep the shovel in position. If a hose is leaking, the pressure will drop, and the shovel can move then. Maybe a hose or fitting was leaking.
