Something I should do as well but I don't believe I could ever get used to living around other people.

The industry terms "Transference Ratio" and "Inter-Axle Ratio" address the whole lead/lag 4wd thing. The question is how much difference is best. On tractors with "front wheel assist" 2-6% front "lead" is common practice.
From any models parts lists its possible to follow the gear tooth count from the rear drive pinion to the front axles - for example my L5450's "Transference Ratio" calculates at 1.508 : 1 (front axle turns faster). This can then be applied to the rolling circumferences of the actual front and rear rubber to get the effective "Inter-Axle ratio". For my L5450 its around 1.04 (front pulling). That's a good ratio, not outside the "skwirm" tolerance for most tires. Its still a good idea to take it out of 4wd on pavement to limit wear.
Pretty interesting subject - especially finding every bevel and planetary gear tooth count in your model so you can calculate it. Sometimes the owner's manuals publish it. More related reading here.

@eserv Do you know if this info is still published within Dealer link or elsewhere? Can you point on how to find?
Why I'm asking... I needed this info (for L4740) and contacted the popular dealer here in central PA. Surprisingly they didn't know and their communication with Kubota yielded zero information. Thought I could help point them in the right direction with your guidance.
It' s time to replace the front 10-16.5 IND tires and the Load radius on modern tires can be a bit larger. Tire manufacture provided the following specs for the older Trac Loader tires. "I did some research and can give you rolling circumferences (RC) from 2009, 2013, and 2016. The RC of 10-16.5NHS Trac Loader was published in 2009 as 89”, in 2013 as 90”, and in 2016 as 93”. "
