First delivery very easy to replace
Don’t like plastic, but if they’re all there is, I had to use it. It works great.

Quick delivery, but check part fit carefully!
I like PayPal payment option and very fast delivery. However the part didn't fit to my machine 100%. It is smaller then original and have different base. I decided not to send it back and at my own risk cut the plastic skirt and made it work. Unfortunately the website do not have "check fit" mechanism, so in order to find the right part you need to do independent research, winch was not very easy in my case and I probably made a mistake.
So if you know exactly what you need, this is a good source.

The fan is plastic so it wears quickly so the blade has no grip to spin. I replace it about 3x a summer.

It's simple to pop off the nut on the bottom of the mower, slide off the blade and swap the fan. A no brainer.

Removed old blade and parts and inserted new ones. Tightened the new nut. I had not tightened it enough and blade became loose while moving. I had not replaced the spacer correctly so I took everything off and retightened. This time it worked. However, I am now convinced that I should just give an eye inspection to the mower before I start it.
