When I moved here to Virginia from New York..I had a good knowledge of operating excavators,dozers,loaders,etc. be that I worked for a landscaping and excavating company in NY for 20 + years, I landed a job with the state highway department here in Virginia and at the headquaters where i'm stationed, the grader operator retired 2 weeks after I started. Well, needless to say, after being watched on how I've been operating the other equipment, they decided to train me on the grader, never have I been on one before. so, the head operator took down to the back of the yard,showed me the basics of the grader, Deere 770C, and left me alone for the balance of the day. He came down and checked on me from time to time..and then told me to go ahead and park it in it's stall..well the next morning when the supervisor was giving out the job duties for the day, he looked at me and said to take the grader and here's a list of 6 or 7 dirt roads that needed to be machined.. the first road I sucked at..lol...had to redo it again...but by the time I got to my 3rd road..they looked good...now..being on my 5th year with the state, I'm doing the training and i'm telling you, you talk about guys being nervous, just the face expression from them as the climb in and look at the levers..
