Interesting topic! An item not mentioned, that is very important is not the weight of the object, and not its friction component, but the force on the attachment to the tractor, and the dynamics of that force in relation to the axles, center of gravety, and traction. Stretching (tensile) loads on really big articulated tractors often exceed their weight by as much as 10 to 15%. this assumes wheel slippage enough to get a large contact patch along the bottom of as many as 12 tires, with ballast in experience based positions to allow 50/50 split of pull from front and from back. The Big Bud 735 (the only one) can pull tensile forces at the 65,000 pound level (best of my memory from 9 years ago) Normal cultivation was with a 60 foot field cultivator at 8 mph at about 8" in medium soil (Montana) If you drag a fair number of logs, build a mini skidding trailer (kind of like a propane tank hauler) to lift the fronts while pulling.
Always keep the attachment point low. Never chain to castings. Always pull from the center of the width of the tractor. Figure out where the tractor will go, and how fast, when the chain comes off the load. Your tractor is probably a 123 now (as pointed out) making more HP and it is fresh. Safety first. JimN

Today's Featured Article - A Question for Dads This recent topic from the Tractor Talk discussion board is being highlighted because it is an awesome display of the caliber of individuals that have made this site their own. The young person asking questions received positive feedback and advice from total strangers who "told it like it is" with the care many reserve for their own kids. The advice is timeless... so although it isn't necessarily antique tractor related, it will be prominently displayed in our archives to honor those who have the courage to ask and those who have the courage to respond in an honest, positive manner.
