To all: thank you for all of your help and information, I have decided, my normal salesman came back from vacation, He is very patient and good to deal with, He felt the 3830 would be the significant improvement in power for what I want, He also felt for my needs the HST would be the way to go, He did not have on on the lot but was willing to find me one, He called me back about 10 min later, found one nearby that had just been invoiced to the dealer, said he could have it to me by thurs, 2000.00 more than I was going to pay for the 3130, Sounded great to me so I went with it.
Now I am just waiting till tommorow evening to get my new tractor and brush hog, He is coming to take the 3130 out of my barn and deliver me the 3830, unfortanately I will have to wait until Sunday to try it out, as I have to work on Fri and Sat, oh well. Probably more tractor than I need, but I go to a lot of barns and have never heard one of my clients say they wished they had bought a smaller tractor, all of them had stories of wishing they had more for this or that.
Thanks again for all of the wisdom, information and help making my decision, I am sure I will have many more questions to come.
