Well regarding the chain, A greenfield actually killed a young boy a few years ago, when the chain came off and it rocketed down a hill. Yes it was in a very poor state, but even well maintained machines can suffer failures.
It is not just the chain, The drive clutch could fail, The belt could fail, even the steering on these models is not great, could lock up and send you sideways. The engine could stall, you will struggle to hold it back with the pedal. Just remember the anniversary models are all over 30 years old now. The brakes on my anniversary 12 are fully adjusted and setup, and struggle to hold it on flat ground.
Even brand new Greenfields can suffer failures too. If anyone ever asks me about a hill block I would always recommend hydro or gear drive. Even they can suffer failures, such as snapping an axle, or popping out of gear. but it is far less common, and far less stress on the driveline for them if used on a regular basis. Brakes have always been a weak point on all ride on mowers.
Don't get me wrong, I love the greenfield design, I have 15 of the things, but they do have limitations, like everything else.
