Craftsman mower lift!

[Dadah]

That appear to be a front I-beam axle fulcrum lift design. It is adjustable for different axle widths. This is a basic deck blade change jack/

The mower must have the rear wheels blocked to prevent rolling away (I think), then the square saddles are lined up to the front axle yoke. One foot is placed on the short cross bar to push forward as indicated by the label, then the handle is pulled back while the jack wheels roll forward, and it lifts the front of the mower off the ground

Im here but I may not be since I am in the middle of 33 radiation treatments. I didn’t ask the question!

Simply not a very safe design....I wouldn't get under a mower using it too easy to have the mower to fall on you.
