What do people use for a service stand for their ride on? (My ride on mowers are Greenfield).

If I need to get under it I usually run it up onto a couple of sleepers on blocks out in the yard, but I want a solution for in the workshop.

The only stands I've seen for sale are where you tilt up one side, or just the front of the mower.
Or motorbike/ATV hydraulic jack scissor lifts.

I want to knock up something solid, and level, probably with rails supporting under the wheels.

Anyone have a good design, especially from a mower workshop?

Cheers
