My dad got my mom a John Deere riding mower in 1994 hoping I don't jinx our luck with. My brother broke the hood so for the last 9 years or so its not had one so it looks like a piece of crap but it is the toughest little tractor to still be running and doing the job we got it for mowing the yard.
Good tips, it's always important to put safety first when operating large machinery, especially tractors. Keeping your tractors in good working order will make them last for decades!
