simple attach - lever, unpin it, put it against the ground, drive forvard - that's it; even simplier than simple trailor jek (and doesnt't weight the ton, like swivel axle)
Toro | Z Masterョ Commercial 3000 - Zero Turn Lawn Mower
ps. for blade change - simpler way than car jack - to lift front of the mower with board or pipe and put it on the car stands;
for quick deck clean-up on the field - one wheel on trailer gate or on improvised ramp
pps. - some strapping ROPS to the trailer (or tree : ))), pulling mower forward - and voala : )))
