Hi oldmatty, and I hope you enjoying the tinkering.

Re: cylinder reel adjustments, if you check out the
very end of our video, you will see my machine cutting grass with no bottom blade contact.
Surprisingly, not a lot of people don't realise that the cutting action of a cylinder mower takes place between the front edge of each reel blade, and the
very top of the
front edge of the bottom blade.
Keeping this edge sharp and true, is most important for the quality of cut.
