New to the site. I have recently seen a few Oliver tractors I am interested in, the 1550 mostly. I am a member at AC.com as well and enjoy the Allis Chalmers tractors and I am looking to purchase a tractor in a few months once I have made my mind up. Would you care to tell me about the 1550 like what is the Hydra power? is it similar to the power director on an AC D-17? And just some basic knowledge on the Oliver tractors. I like how big these tractors are as well, seems they are bigger than most tractors with similar hp ratings.
