At 1100 lbs the mower is too heavy for a light weight lift. I tried various jacks and jack stands, then a lawnmower lift, and now have settled on using metal car ramps and solid rubber wheel chocks. Both from Harbor Freight. The metal ramps are just a tad higher than the poly molded ones and its easier for me to access the center blade from the front. I do have to stop short on the left side so I can drop my left side blade bolt out without binding on the ramp. Once I figured this out its been much easier to do. Like a number of others I tried the electric cordless impact to remove and retighten the blade bolts and its worked out fantastic for me. No backup wrench required and no blade slippage in use. So far so good.
