I have a Yard King 21" Self Propelled Gas lawn mower, the front wheel is gone as the gears on the wheel are gone, need a new wheel, but not sure who makes them, asked few shop, no one knows.

Please help me to get the part no. and the manufacturer of this lawn mower

Model #?

Sometimes even after a manufacturer stops making parts, the parts are available aftermarket.

I believe the mfr is Murray and the assets were acquired by Briggs & Stratton.
