Engine is a Tecumseh flat head. Don't know the mower.

just managed to get it going, wow it is powerfull. i have to turn it off with a stick. am going to sharpen and add a few more blades. is that a good idea? have heard of one with 8????

More blades wont make a difference in cutting...just increases the chance of the bolt breaking and you or an innocent bystander getting severely injured from a flying blade. I wouldnt do it.

i put two new blades on after a bit of a sharpen,

may keep this one
