I just got an Everride Scorpion stand on mower 52" used. I am having a heck of a time trying to figure out how to do a few things: 1. How to gain access to the blades. I have it propped up on blocks that are maybe 8-10" off the ground and maybe (with front wheels) have 12-15" clearance but still not enough to be able to change them. Do I need ramps or something? How does one do this? 2. How do you get the bolt to the blade undone without the blade turning? I tried a socket wrench but no go. Do I need an impact wrench? If so, are they pretty easy to use? Again, I need more clearance and need to know how to keep the blades from turning. If anyone can help here, it would alleviate a lot of frustration. Thanks a bunch!
