If you try to describe the mower you have it's possible that someone on here might be able to suggest a model number - trouble is though you give few clues - gas - electric - push - rotary - cylinder - hover - size - maker - all these are missing along with the plate!

I can answer this question...
How do I find the model number if the plate is gone?
