The lease for 2 yrs and return programs I have not looked into. I would think they would work with high mower hour operations (if you put 1000hrs on a mower a year it could make sense).
You would need to go over your numbers to figure out if the lease makes sense. I don't find my mowers breaking down much, so if the machine is solid I'm going to still run it.
Looking for blown Kawi 29HP DFI engine's fd791d, whole thing, intake, throttle body, and electronic's. PM me if you have something you would like to sell.
