Question

Has now stopped working completely. When it stopped it emitted a lot of smoke. Thinking oil may have leaked...blown head gasket. Took to repair shop. What would be cost of repair? Is 5 years old, mow 2 1/2 acres per week. Use for hauling in trailor, rocks, gravel and topsoil. Will the cost of repair be worth or should consider a new mower.

Answer 2

Is it oil smoke or fuel smoke?  Usually oil smoke is lighter in color.  Fuel is dark and smells like unburned gas.  If it is fuel it could be a carburetor issue.  If it is oil it is most likely rings or a damaged pistion.  Have you checked the oil level?  You didn't overfill it?

Answer 3

You paid pretty big bucks for this tractor new didn't you?  If you put a thousand into repairs, it would be cheaper than having a new tractor.  My question to you, is how can you do preventative maintenance more often and more effectively in the future.  I'm saying the tractor didn't get there by itself.
