Hi Yard Machines rear tiller looks like 216-430-000 but no numbers on mine. was running tilling fine when all of a sudden tines stopped spinning. When shifting to till feels like no positive engagement. I'm assuming the drive chain broke but I can't find a good diagram of how to tear down and repair any help would be great thanks

There is a SHEAR pin that could also be broken. It's there to protect the sprocket from breaking in the event of hitting a rock or something large while tilling. You will have to go to the MTD website who makes Yard Machines, to get the directions on changing the pin or the chain whatever the case may be.
