That was an interesting string. I have to admit that at first I thought it may be an old wives tale that type of spring impacted traction. After a static diagram or two it is clear there is a relationship between spring rate constants (stiffness) and keeping near equal weight on both wheels on uneven ground to keep one from spinning. Leaf springs are used in heaver automotive applications. Thus making it appear the leaf springs are bad for traction when actually a stiff heavy duty coil spring would not necessarily perform better. Summary - flat ground it makes no diffence. If one rear wheel is on a hump and the spring is stiff, that wheel picks up much more weight which is what causes the spring to compress. Weight is no longer split 50/50 between wheels and spinning is more possible. If the spring is less stiff much less weight is used to compress the spring to compensate for the hump and weight split is closer to 50/50 thus more traction. On paper does the spring rate constant make a diff - yes. In real life does it make enough impact to matter to you? You get to decide.
Now to go further out on that limb. The front springs change things as well even on 2wd. The front springs resist the vehicle tilting when one of the rear is on a hump. Softer front springs allow the vehicle to tilt more which in turn allows the back spring on the hump to have to compress less. Less difference between rear spring compressions means closer to 50/50 weight distribution for optimal traction. Soft long travel springs all the way around provide better starting traction all other things the same.

Today's Featured Article - Tractor Profile: Farmall M - by Staff. H so that mountable implements were interchaneable. The Farmall M was most popular with large-acreage row-crop farmers. It was powered by either a high-compression gas engine or a distillate version with lower compression. Options included the Lift-All hydraulic system, a belt pulley, PTO, rubber tires, starter, lights and a swinging drawbar. It could be ordered in the high-crop, wide-front or tricycle configurations. The high-crop version was called a Model MV.
