I'm happy for you that you found something relatively simple to fix. Welcome to tractor ownership. Trust me it won't always be that easy. Any tractor that gets used is going to have issues. Like the other guys said, unless the fluid on your dipstick looks brand new I'd get new fluid and a filter as soon as possible. Same for the fuel and engine oil. Tractor supply's premium hydraulic oil is equivalent to John deere hyguard. And they always say someone just bought the last one when the truth is they don't stock shit. I usually just order most stuff online.
