I bought one new 12 years ago and still have and still really like it.
Its never broke or broke down always starts and runs perfect, I replaced the mower deck drive belt after 12 years because it squealed a little to much when I engaged the mower deck.
I've never had to do anything to it, other then the belt.
Don't grease the 38'' deck, the manual that comes with the tractor says its a sealed unit and greased at the factory so don't grease it. You will see the grease zerks on the deck but don't grease it.
