Do the math

You don't give the specs on the JD 1635, thus I have no comment.

The 4630 and 1066 were as they came from factory, 4630 had about 400 hours and 1066 around 8,000 hours, and it was the Deere owner's opinion not mine. I had driven his tractor but never at max. pull. I never figured either one of our tractors were anywhere near max. pull on the disks we had. Both tractors had been bought new to run forage harvesters.

The 4500 bales per day was not a one man hay day, but rather about 15 to 18 men. Small square bales have never been about horsepower, just pure manpower.

No one said anything about any tractor out pulling the other. The Deere owner knowing full well his 4630 being rated 20+ hp more than the 1066, after using my 1066 on his forage harvester, said, "It makes my Deere look bad". He didn't say it ran away with the harvester, he didn't even say it did as well as the 4630. I forget the exact ratings but that 4630 would have been rated around 150 hp. It was always my opinion that he the owner of the Deere was somewhat disappointed with his tractor. By the way that 1066 was turning 150+ the day it was new, it was turning 150+ at 4,000 hours as it was at 8,000 hours, and that was as it came from the factory.

This discussion started out comparing offset to tandem disk, that my friend was the question, in case you hadn't noticed.
