So just recently bought this yardman mtd I have no idea what model or year. Bought it cheap, to be exact for $33 needed some repair so I started diagnostics because I wasn't told reason why it stopped working. So I tried spinning it by hand and to my surprise it would only spin 1/4 of the way before it stopped decided to check oil. no oil so I put some oil i had laying around and boom i could rotate it with one hand no problem, no noise sounds like everything is good besides that. Checked the oil a little bit and noticed it was low. I checked underneath and it was leaking. decided to take the engine out and it seems from what I read it's the bottom seal but have no idea I just know its coming from where the pully goes into. So I guess my question is, is it the bottom seal? what can I do to repair it. How Hard is the repair. So far I have $33 into it and a couple of hours not looking to spend more than $150-$200. And I would do the work myself unless the labor is not that expensive. And also is it worth my time and money. also I dont now much about it so some info about the tractor would be appreciated
