Congrats on your choice of weapon and best of luck in getting it to where you want to be.
For me, it all depends on how you want to go about the restoration. You can read and read on how others have done it and then apply the knowledge or just get in there guns blazing and make it up as you go. I think I've done a mix of these on my own in progress... What really helped me was a post by a wonderful young lady "emk3" and her journey.

The bed knife bolts are amazingly tight and of course you have a few options. Heat can work, or just take the unit to your sharpening engineer and let them do it. If you attempt this yourself just be very aware the cast iron sole plate is brittle when handled improperly and quite expensive to replace. When my old machine was being torn down we had to use the tool below with a precision strike. Think of it like a manual impact driver.
Bonnar_Bloke offered me the following link when talking about the front roller and that's how I'll go. He's a great resource of knowledge and I'm amazed at how patient he is with responses and he never misses a chance to add to the discussion. I see you are geographically matched too.

The rear roller is another story. If you have any hard surfaces between its storage place and the lawn, they're going to scratch any paintwork you try. I'm trying a different approach over the weekend and hope to report next week.
Best of luck with it and keep the updates flowing.
TC.
