I learned this during my tractor pulling career, it used to scare the crap out of people. I'd strip the tractor and get in the lightest class I could, and let it rear up. Go a couple hundred feet with the front wheels 2' in the air.
Front end will come up until the axle, hitch point, and other end of the hitched cable / chain are in a straight line.
Any more than that, the hitched cable is now picking 'up' on the hitch point, causing the front end to tilt down.
Only caveat to this is keep the center of gravity in front of the rear axle, and the hitch behind. Easy to do with a tractor. Probably with a three wheeler too; I'd say you'd be quite safe.
IF you don't care where you are you can never be lost...
