Congrats on the Caroni.
I never thought I would want a 3pt tiller. Never even entered my mind. Until I got tired of having to get the angle and the speed of a disk harrow just right. Then, even after I had everything "just right", having to go back over the area with a drag to level and smooth everthing back out. If your garden is already busted up pretty good from years of working the soil, one pass with the 3ph tiller will do ya. If you're breaking new ground for a garden, three or perhaps four passes with it and you're done.
A 3pt tiller is the way to go.
