I just purchased a NH LS 45. A year ago I had a NH LS 55 which I had for about a year. I had great luck with it and sold it as I have a business now of buying and selling tractors, after I go through them and make them as close to perfect as possible.
I just hired an electrician, who has worked for me in the past, and he is the brother of my mechanic. He is the one who bought my LS 55 and said after a years time he has had no problems and he loves his tractor. they are solid machines built like a ____ and run great.
The other reason I bought another LS is I still had an almost new rototiller and plow for it. Very happy with my New Holland LS 45. I also own a Cub Cadet 2135 and just bought a JD 317 which I need to rebuild. A winter project.
