Redlevel,
I was in the exact same position as you looking for a 40-50hp tractor. I am not attached to any color paint like green, blue, or orange so I figured I would look at all of them. I spent 6 months looking at POS used tractors, and started to get frustrated, so I decided to go new. Long story short is that based on my needs and the amount I wanted to spend I decided on a NH Boomer 50, and then a buddy said I should just buy from LS tractor directly and save some cash. Holy S***, what a great piece of advice that was!!! Turns out that the Boomer 50 and LS 4047 are near twins except for a few cosmetics... And as a bonus the LS comes with 2 remotes and a universal mounting bracket on the FEL. The NH dealer near me has a free loader program going on if you don't use 0% interest, but even with that it was almost $5,000 more than the LS.
Anyway, that's my 2 cents on my journey, based on my needs and bank roll.
