People don't seem to want to admit that per the Nebraska test data the unballasted weight of the 350 was almost 500 lbs greater than the M. And, due to the additional power of the 350 it was then ballasted heavier and weighed over 1500 lbs more than the M during the drawbar tests. Combine that with the lower gear ratio provided by the TA and it should no surprise that the 350 had a greater first gear maximum pull. The physics don't care what model number emblem is on the side of the hood.

It does have everything to do with traction and given equal tires the tractor with the greater weight on the drive tires will win the tug-of-war.
