Chain host on the front end will get it up nicely. Some people will run 1 wheel up on their trailer ramp giving them access to one side blade and the center blade...then repeat for the other side. Get a jack under it and some jack stands. Many ways to get them up in the air.
You need a wrench on the nut at the other end of the bolt. I am pretty sure those use the same system as the Wrights and most walkbehinds.
