Once you get it back on firm ground and have some time to play with it, do take time to practice some of the moves as suggested. Not only are some of these techniques useful for getting a machine unstuck, but also for regular everyday digging tasks.
For example, you need to get proficient at pushing the machine along with the hoe, which is the only efficient way to move forward when trenching. Also needed when lifting/pushing yourself forward to jump over an open ditch or trench. Next is lifting the machine and pivoting it side to side with the hoe. This is used to quickly square up to parallel sides of a wider hole or trench (say 6-8’ wide) as you are digging it. Also useful for getting yourself on or off a trench you are straddling. Lastly using the hoe and loader together to lift and walk the machine, useful for getting up and out of deeper excavations with straight walls.
Some of these are pretty advanced techniques and situation you
may never need, but others you’ll encounter regularly. I see it all the time where new operators just view a backhoe as a tractor with a couple attachments on it. Don’t be the guy who digs a few feet of trench, spins the seat around, lifts up the outriggers and loader, and puts it in gear to move ahead a few feet lol.
Mr. Jimmynoshow, I'm also not an operator. I bought a JCB 1550B essentially cold turkey (from brother in law so was trusted source)
One thing I did in the very beginning was to go down by the lake. Put machine down to idle. Dipped the backhoe bucket into the lake to fill it. I tried to move that bucket as many directions as I could, without spilling any water.
I can't say factually how much that helped me learn but I don't think it slowed down any learning!
Also, what MG84 says above makes a lot of sense.
I looked for pictures (which I know I have) and can't find them yet. I live next to a managed lake. They lower the levels during winter and let it raise back up for spring/summer. (It's a TVA, Tennessee Valley Authnority lake)
I obtained permission to take my backhoe out to the now exposed 'beach' since the water was down. This would otherwise be maybe 4-5 feet deep when the water is up. I used the hoe to skim some muck and dumped it closer to shore. Later, I scooped the pile near the shore and dumped it into a smaller tractor that had a loader so someone could carry it to a ravine on the farm.
Win/win....until I sunk down to my axel's. I was utterly dead in the muck. I am however, persistent. I had thought of several things.... try to pull it out (brother in law has some heavy machinery) maybe tie off to a tree and see if I could roll bucket over & over & over to inch my way out....
I finally used hoe to push wheels out of the muck, had outriggers down to slow sinking back in. Used hoe to crab the back end around (I was facing INTO the deeper lake so going in reverse just slung mud) Used the hoe to move up, over, down..... up, over,down.... again & again until I could redirect towards the shore. I also had to raise the front bucket so things weren't binding up there. Once pointed in the right direction I then did what I call "pogo'ed" Put the front bucket up, I don't recall if the outriggers were up (probably) or maybe down partially to protect a bit towards rolling to side. Just like you might do a push up.... I used the hoe as an arm to push the machine up and forward and also had (if I recall) machine in gear so wheels were also trying to move (2-wd)
I had let worry get in my way and I just "knew" that it was stuck there forever and "soon" (like 5 months later) the water was going to rise and ruin everything..... that was very unfounded as there were other ways to also try to pull it out BUT, pushing with the hoe did it. Not being familiar with your machine, I'm going to presume the hoe can easily lift and shake the entire machine so it has the power, you just want to be pointed in the right direction.
