I put some heavy duty casters on mine with lag bolts. When the stand is in the upright position the wheels don't touch the ground. When it is time to move it just tilt it back a little and off you go.
get a rod the size of the inside of the wheels, usually 1/2 inch,, or all thread, and put a bushing on it for a bearing, washer and nut each side of the wheels.
I use a big wheelbarrow to move my larger motors around the yard, from garage to the shop. And a 4X4 winch on the rafters to haul it up and down. Keep the CG low when moving it and use the right harness for lifting. Plan ahead and save your back and limbs...surgery sux.
