Given a ride on mower last year and been impressed. Offered for free said I didnt need it, then asked to just try it. Did and was like a 12 year old kid with my first mini bike. I noticed last bit lifing the height aduster left side was not coming up and down just staying on the ground as the right went up and down. For whatever reason cutting it was cutting even set on 7. Other day I turned in the field behind and guess hit some higher ground left side and its stopped cutting. One belt was partiall off so put that on but seems one blade is not turning and one is and can even bump into it

Do they have shear pins for the blades. Realize I need to lift it up and start poking about. Know there were lots of you tubes on that model as well. Quick look with not enough time didnt find what I might have done but likely its there. Any thoughts appreciated.

Is there a spring or something that is supposed to hold the left side same as the right side as you raise the deck up and down?
