Have a Troy Bilt Super Bronco, engine has a hole in it large enough to put your thumb through after about 70 hours of use. Tractor is out of warranty and Troy Bilt Customer Service, (a real oxymoron).
couldn't care less about the issue. Told me they didn't make the engine, therefore not their problem. Also told me I "probably" forgot to add oil, even though engine is still runnning with hole in it, albeit pumping oil out through hole in the short block, can't run it for long.
C.S. at Troy Bilt really is a joke, someone who is just trying to get you off the phone as quickly as possible.
