OK Kirk. Here's the Spanco in action doing what I wanted to use it for.
Rather then removing the deck to change blades, I just jacked up the whole front end.
I did use a couple lift straps over the beam as a backup to the chain hoist. I'm still searching for some tube to make my extended reach "jack stands".
And I think I may have found the reason why my deck has been cutting unevenly.
One of these things is not like the other, eh?
