Maybe a daft question. My lawn mower ( a Champion Sovereign or something
like that - self propelled) has just blown up. Well, it gave out loads of
white burning smoke that filled the garden and stopped working and it made
this sizzling hissing noise. OH doesn't understand when I tell him it just
went up in smoke.

Is it repairable or am I looking at getting another?

Any suggestions for an alternative? ( I have to have a large cut and a self
propelled as the grass extends to about 1/3 of an acre on each lawn.)

Thank you.
