Here's my just finished 430 restoration. Has just over 1100 hrs on it, 1 original owner that I bought locally about 2 years ago. The drive train had fluids / filters serviced regularly and only required maintenance and adjustments, but everything else there but not so good shape.
The mower deck was the worst. I'm working on that now, disassembled and then sandblasted. Fabricated repair panels, welded in with strengthening ribs will be ready for the powdercoating in a few days.
I love it! After all the hard work, waiting to source NOS parts it looks and operates like new. Its really almost too big for the lawn that I have.....but that's point isn't it?
Everything but the hood is powdercoated as that's how they were manufactured. The rear tires are weighted with RV antifreeze.
