Troy Bilt MTD Piece of junk, no customer backing Internet

Purchases a Troy Bilt Super Bronco, thinking Troy Bilt was qaulity product, based this on my tiler, which was built b the actual Troy Bilt company, many years ago. Piece of junk from beginning, but the kicker is the engine blew hole in short block at around 70 hours use. Hole was big enough to put your thumb through. Customer Service, truly an oxymoron, told me I "probably" forgot to put oil in it. I explained it still runs, and wouldn't if it had run out of oil, they couldn't care less, and couldn't wait to get me off the phone, guy sounded bored and disinterested, also found several complaints about this tractor, cracked blocs and blocks with holes in them. Repair is $1500, about $100 more than the tractor cost.
