This sounds a little crazy I guess but it works great. I have a about a 10' X 5' trailer I use with my mule. I'll run the mower up on that trailer then back it up to my other trailer. Then I roll the back wheels off on the big trailer, set the brake and block the wheels well. Slowly pull forward keeping a good eye on the lawnmower on the small trailer. When the front wheels get close to the rear stop and block the front wheels too for safety. Again make sure the wheels are blocked and the brake is set. Also, make sure you're on level ground. I've even used benches and outdoor chairs for the rear wheels but it just didn't seem safe to me. You could even use a truck bed I guess. I've used hammers, cheater bars and everything else you can imagine with no problems. Just keep your eye on the wheels and make sure they stay blocked.
