Just remember that when you are running "tennessee backhoe" , and the work is greuling ,that pain is weakness leaving the body. You have to develop the ability to focus thru pain. A while back ,we were digging up an old septic line at a farmhouse. The backhoe was having a hard time pulling up the 3in main that was embedded in concrete. The crete ran from the house to the hunny pot. The homeowner was observing our production, and told us that her father had installed all the concrete (mixing by hand) all the no hub cast iron pipe, and the septic tank, as well as the feelers by himself. The only hand tools used were a pick ax and shovel! After I gathered my thoughts about how much WORK this man did, I mentioned that her father had to have been a very strong man. She replied,"oh yes, he could squeeze a pair of pliers in his hand and flatten the handles". Now that was a real man.
