No, but I'll only raise the front end 2 feet. If I were going completely vertical with the machine, I'd drain the fluids.
Brin was talking about raising almost vertical.
Your still having to crawl underneath with the front wheels only 2 feet off the ground. Are you removing the blades or just grinding them in place? I have the same problem getting back up as you explained, without using my arms to help pull or push.
The little Deere my wife uses has a 48" belly mower under it, and I hate to do it, but pulling 4 pins, tying the lift arms out of the way, and sliding the entire mower assembly out sideways is becomming the least stressful on my old joints.
