Here I use a two ton foldable shop crane. I initially brought for automobile engine work but have used it a lot in mower repairs. My back just let me lift heavy things like when I was a teenager due to a work related back injury. Yes I know it is over kill but I rather use it instead of hurting several weeks because I didn't use it. The only problem is the legs get in the way at times which is why I working getting a gantry type crane besides I needs to lift my truck bed so I can replace the fuel level sending unit in the 30 gallon tank.
It makes removing and installing engines easier and for lifting large ZTRs so jackstands can placed under them for dropping the transaxles. For smaller walk behind mower I made what is basically a solid top pallet sits on large lawn cart trailer. It can stand to a little higher but it takes less room and allows me to use the cart when I need to lawn supplies.
Anything you do to make the work easier and safer is a plus in my view.
But boy am I going to have fun Sunday. My air compressor quit working and now I got dig it out to find what failed. Appears to electrical in nature. Just put on a new motor and pressure reply four years ago but that doesn't they are still good. Boy do I have the compressor packed in place and with the rain I got to wait for it stop for few hours during the daylight hours to move thing out. Some might not go back.
