It burns it and uses some When you engaged mower it would shut right down,tractor started right up and ran.Put anew plug in and everything worked,now plug is fowled again

if it puffs blue on a throttle up or a throttle increase from the governor, then it could be valve seals.

if it just plain burns it blue, then I'd be looking at oil control ring.

How is the rest of the machine? If you've worn out the engine, then it's likely the rest isn't exactly in stellar shape.

Time for a new one?

What brand of engine is this? Briggs, Kohler, Honda, Tecumseh, etc. Some Kohler models had a problem with the head gasket failing which caused them to burn oil. I have repaired two of them with this problem it the last year.

Agreed. With proper maintenance, the engine should last longer than travel parts and cutting parts
