Don't have an X-one but do lift up around 300 mowers / year
I use a modified engine hoist inside the workshop.
Changed the V shaped legs to U shaped so the legs clear the mower wheels.
Good for 2 tones & can stand any mower vertical or with a spreader bar can lift the mowers horizontal 4' in the air.
Even better it can be used to lift anything so is quite versatile.
Outside I have an old yard crane , again a saddle frame, designed to straddle pallets.
THis one has a 4 ton lift so really good for working on the truck as well as mowers.
