Induced Parkinson’s?

Can some of the symptoms of Parkinson’s disease be induced and can this lead to Parkinsonism? I’m asking this question of those who know the literature on biomechanics. My dominant symptom is left hand/left arm tremor. I also have stiffness in my left shoulder. In scanning my memory I recall (before diagnosis) having had what I call incipient tremor in my left arm after using an electric hedge clipper or a gas operated lawn mower. It was especially evident after using the hedge clipper. Does anyone know if this could play a role in inducing Parkinson’s? This topic may have already been covered but I don't recall it.
