Not really.
I was pondering life the other day and my eyes wondered down to the shifter area and I saw the hi/lo gear switch in my truck.
I’ve played with it a little when I first got the car. Don’t really understand the purpose for it, so here we are.
Say I am on level ground in snow and need to get the car/truck out. I put it in low gear (Transmission in L, no LO). Rock it back and forth. Raise and lower suspension if I must squish snow under the car and out I go most of the time. Not using LO gear. Still in HI
Best I can tell is that the LO gear is used for going uphill if your engine is not strong enough to rotate tires to propel up/forward.
But then - what are you driving? Scooter? What engine is not strong enough to propel the vehicle?
Why do we have it? When are we to use it (if not going uphill)?

LO generally indicates a slower gear ratio than than HI. This lowers your speed, but increases your torque. So say you’re going up a hill with a loose surface, and as you ascend in HI, you find your tires are slipping. Putting it in LO will slow down the wheel speed, but will allow you to use the higher end of the engine RPM (and the power if provides) without spinning the wheels. Ideally.
Outside of going up a hill, or down a hill, I don’t know that it has much purpose, unless you’re pulling something massively heavy (and not going very far with it).

So basically a way to no spin wheels while accelerating when going uphill?

It also gives you better throttle control if you are in loose ground. In first gear in HI you might spin the wheels by just touching the throttle, LO will cut the wheel speed by whatever ratio the transfer case is.
The added torque is also very useful offroad in technical areas and when pulling somebody or something that’s stuck.
