I was one of those teenagers could run anything. Both my sons surpass me on my best day. I had occasionally had a fraction of a day I would have opportunity to run excavator, or backhoe, I just loved it! Several times, I rented an excavator.
About 22 years ago I bought my own backhoe. Like most used old machine purchases, it had problems. After diagnosing the problem, it took forever for parts to arrive.
I needed a backhoe, so I bought another, This was functional but not loved. I found another in very nice condition, close sibling to the previous. This I kept 15 years.
My son's friend is no mechanic. He bought a backhoe to do his own site work on construction projects. He was disillusioned after two years, wanted to sell. I bought his also.
I didn't need two, I sold both, added some more money, bought a low hour machine a model still in production.
You'll either quickly learn to run it, or find it isn't for you.
