MTDGenuine Parts Air Filter

Q: Will this fit the Toro Lawn mower?

Cannot answer without knowing the Toro model number

Q: Will this fit a Powermore oHv lawnmower

I can’t say for absolute certain since you didn’t give much to go on but I think Honda supplied many of these OHV engines for companies like Yardman and Powermore. If it looks like the filter you have try it. I know how hard they are to find so worth trying.

Q: I purchased one last year and it didn't fit. What is the demisions?

Not sure, look at the product description, it should give the size in inches.

Q: Will this item fit a sears 159 cc my stride front wheel drive mower ?

Here is all I can tell you, my MTD has a Honda engine on it and this filter fit perfectly. If I were you I would try to find the OEM part number for the air filter and see if this cross references to that filter. Good luck
