I've had to chain up my tires more than once to get out of a muddy area.

My old Columbia would look at soft ground and get stuck before you even tried to move it. LOL

My truck would have pulled though that I think.

Cross lock
Diff lock

Worst comes to worst I ask the dude in the dozer or jlg to give me a hand.

"The downer you go, the worser it gets."

That's advice from an experienced oil field driver I keep in mind.

In sand, mud, gravel, or deep snow you NEVER EVER want to spin your drives. That will only cause them to go in one direction...

...DOWN.

If you find yourself in a situation where your drive tires have dug a hole in the soft terrain, then your best option is to "rock" yourself out of it.

Start in Lo and throttle forward GENTLY until you feel it ALMOST want to spin your drives, then push in the clutch and roll back and JUST as it almost stops against the uphill of the trough at the back engage the clutch and give it throttle to try to catch momentum to top out on the front side.

If you don't quite make it after a try or two, try getting into reverse as you almost top out on the front of the hole, to get into the top of the back of the holes your drive tires have dug. Then get into Lo or 1st and juice the throttle and try to power GENTLY over the front of the pit.

You should always have the power divider (aka Interaxle Differential Lock) engaged in ANY slippery, soft conditions. Otherwise you will spin out only one of your four sets of drives.

I have done a fair amount of mud, sand, bottomless gravel, and deep snow with only a power divider. I haven't yet tried letting air out of my drives, but might consider that in the future if I really get stuck.

The rocking method may be problematic with an automatic. I've never driven one. I have driven over a thousand different trucks, mostly drive away for oil field companies, and NONE of them were automatics. My own truck is an old Swift O/O truck, with no full lockers, only a power divider. So far I have never had to call for a bulldozer to come rescue me.

You can "rock" an automatic, but they aren't very happy about it. I've done it a few times, usually causes it to throw a code that has to be cleared later.

I'm all about code talkers.
