Routine maintenance on any engine can go a long way to preserving its life. I have a collection of old 2T Lawnboys that have been cutting grass for 30 years or more. I am sure none of them would be considered 'commercial' grade what ever that actually means. If commercial grade means used by commercial cutters a Walmart special thrown into the back of a rusting Ford pickup is commercial grade.
What gauge is your deck? Just curious haven't been back to the dealer to check. Need to go this week for carb parts but haven't made it yet.
