Ray: I presume you are looking at Nebraska test data. I doubt if there is a mistake on the weights pulled, as they also factor in mph for their drawbar rating.

On the weight and pulling ability of your 300, weight of tractor is not everything. It probably was when the 300 was new. I ran 13.6x38 tires, chloride and wheel weights on my Farmall 300 simply because it hauled a lot of hay and silage on hard ground. In a field working situation and with the advent of big horse power tractors, we are finding more rubber on the ground just as effective as added weight. I ran my 656 and 560 diesels on 16.9x38, 1066 on 20.8x38 duals, no added weight of any kind. I also had a 540A Deere forestry skidder 18.4x34 all around, no added weight, Pulled a 20' disk with the Deere. Those tractors probably could have pulled a lot more weighted, however on a dairy farm, pto are your big hp demand. I had no problems pulling a 25' field cultivator, 12 ton manure spreader or forage harvester with 20' wagons with 1066.

In the past ten years we have started seeing 42 and 46 inch tires on tractors and 4x4 on just about everything. This is being done to put more rubber on the ground and cut down pounds per square inch, thus reduce soil compaction as well. I was at a farm awhile back and one of those 8 wheel, 300 hp, articulated Deere's pulled into shop where there was about 2" threshold in doorway. That thing bounced just like a baloon would. I'd be willing to bet the ground bearing weight in pounds per square inch on that big Deere is probably about half what your 300 is. Your 300 will do well to pull in 2nd gear 3 times it's own weight on a flat bottom stone boat. My guess is that big articulated tractor is pulling 5 to 6 times it's own weight using the same criteria.
