Hey Red, I haven't done alot of pulling myself, but I've done best with just alittle amount of slip. More of a slip, I guess, than a spin. You're right, if you get a good spin going, you're done. I start out kind of low on the throttle, then watch my tire tracks as I advance done the track. If the track is just right (not to dry or too wet) I get just a little ripple of earth off the treads. A spin will wipe the track clean. Clean track behind the tires, ease up on the throttle, a crisp sharp lug print, give 'er a little more. Pulling is about torque. Think of your tire like a lever, with the track being the resistance end, effort distance is kind of the radius of your axle, and the fulcrum being the center of the axle. You can't change the center line or radius of the axle, but a taller tire increases the resistance distance, thus requiring more HP to "lift the load" or advance down the track. You kind of dance this dance until the sled weight advances closer to the tractor, then you give 'er all she's got. My tractor is a diesel, so once she lugs down, there is no govenor to bring her back like a gasser. The early Farmall diesels didn't have the hp their gas relatives had, so its all in the operator's throttle hand, IMHO.
Alot of physics go into pulling. We need JimN to chime in on this
