JerryG, I tried to give a complete answer.
Often times in court, a lawyer will ask a very specific question and the very specific anwer will not tell the full story. I think that type of question/answer session is not mearly misleading, but borders on lying.
In the case of tractoring, a very specific question may be asked for several reasons, and some of those reasons may include that the person asking the question does not understand things fully and I fall into that category on many topics. So when I answer, I try to give a complete answer that may be mildly off topic, but still relevant to the overall issue.
So to be more blunt, the answer is YES.
But to be more accurate, it is only YES IF THE OPERATOR IS GOOD WITH THE PARTICULAR SHIFT METHOD ON THAT PARTICULAR MODEL TRACTOR.
And to be even more accurate, YES, BUT ONLY IF THE ABOVE IS TRUE, AND THAT DOES NOT TAKE MANY OTHER VARIABLES INTO ACCOUNT AND IT ALSO DISMISSES THE NEED TO BE PRODUCTIVE.
Hope that clears up my thought process and clarifies why I am so darn long winded with my answers so often!!!
