Use a Strong Winch to Pull Yourself Out
Sometimes, there's nothing else to do but to use a winch to get yourself unstuck. If you find yourself in knee-deep mud and your vehicle won't budge no matter what you do, it's time to break out the winch.
By using a strong winch to pull yourself out, you're effectively relying on the pulling power generated by the winch as opposed to traction generated by the wheels or engine horsepower. However, winching can be potentially dangerous since you're essentially operating a powerful electric motor stretching a synthetic rope or steel cable that's under a lot of pressure.
Before even attempting to winch your vehicle out of the mud, you should assess the situation and make sure that you can safely use the winch. To do so, you need to check the terrain, the strength of the winch, the tow points, and the location of obstacles or hazards that could interfere with the winching process.
Once you've determined that it's safe to winch your truck out of the mud, you'll need to attach the winch cable or rope to an anchor point. The anchor point needs to be a solid, fixed object that won't move or become loose under a lot of stress.
This could be a big tree, a large rock, or even another vehicle that's as heavy or heavier than your vehicle and is located on a sturdy surface. Make sure that the anchor point is strong enough to support the weight of your vehicle and that the winch cable or rope is securely attached.
Once you've done that, you can engage the winch and slowly begin taking the slack out of the cable or rope. As it tightens, your vehicle should begin to slowly creep forward. Keep the winch engaged and continue pulling until your truck is back on solid ground.
This goes without saying, but it's really important to use caution when winching and to wear safety gear such as gloves and proper eye protection. Get bystanders a safe distance away from the winch and the truck so that if the cable snaps, it won't hurt anyone. It's no use knowing how to get a truck unstuck from deep mud if you don't do it safely, so always remember to put safety first.
