G'day all,
I find it a considerable advantage to have an 'island' mower workbench, so that you can walk all the way round it, without having to spin the mower around. My family's OPE business built a couple of these benches out of timber packing crates, back in the day.
Mine is a simple timber worktop, which clamps on to a small 3-legged grid top welding bench I made up years back; as I can still manage a straight lift, to get my push mowers onto it. I don't work on gear I don't own, these days. Can take pics, if desired.
For a commercial equivalent with lift capabilities, what about something like these units?

Would just need a 'stop rail' or two installed for mower use, to stop the mower rolling off the trolley top.
