Hello This is a 15 year old Sears Craftman LT1000 lawn tractor. Besides changing the oil, oil filter, gas filter and general cleaning, This year I changed the carb https://www.hearth.com/talk/threads/craftsman-lt1000-tractor-not-starting-up-quick-putrid-gas-smell.175286/ And the mower blades plus cleaned and lubed the mower deck. I used the wire wheel to get the crud & rust off and some “Dry Moly” spray to keep the grass from sticking. Also a little light weight Anderol 465 Synthetic bearing oil. The old blades are just dirty so maybe I can take the time to clean & sharpen them to swap them out for next year? What kind do you have? What did u do & what do you use?
