Driftless SW Wisconsin | Ridge till is controlled traffic - but there are many passes through the field and the duals straddle the same two ridges on every pass.
A tracked tractor helps a bit by limiting the number of row middles compacted and possibly the peak ground pressure (psi) exerted but can cause more damage on the end or in curves. Even psi numbers can be misleading - you have to look at the actual psi under a roller...but that's another issue.
We have had good luck making decent strips where we have been forced to run in track paths, such as on a quadra-track with 30" belts, compared to trying to make a strip in a tire track behind a bias ply tire.
There are two main components to pinch row yield loss in a given soil type and moisture content: ground psi and frequency of driving over it.
By reducing the tractive effort required for any given operation, including strip till, we can reduce the tractor weight required to transfer hp to the ground and also the ground contact area required for example singles on a lighter FWA tractor in place of duals on a 4WD or 2WD tractor. It is all tied together...
Here's a photo of one of the neatest operations I've seen - he was deadheading back from the opposite end of the field - not going over it twice.

How much tire pressure in duals?
