Thanks for all the hints and tips fellas, I wish I took some photos before I started all I have is pics I have been sent for purchase!
Yeah I have gone in all guns blazing didn’t take any photos during tear down of both mowers but I think they are surprisingly simple machines! First 1 took me about 3hrs and second took 1 1/2,
Will try take some photos before and after blasting/painting!

I have 2 different front rollers one has the plastic end caps the other is all metal! Also wasn’t going to take rear roller fully apart unless was going to blast! Just split and clean I think as not going to change or improve the function! Is it worth opening up and painting?

This resto is for a machine to use on my new lawn I am going to put down in spring.
And prepare me for a full resto on the unicorn I picked up!
