You are a veritable fount of Oliver plow information! Thank you!
A friend found the plow sitting in a salvage yard waiting to be recycled. He knew I was looking for one and called me. I plan to bring it home and restore it to use, not parade quality, but practical use.
One more question.... What is the purpose of the long threaded bolt ajustment on the front of my 566? Is it simply to fine tune cutting width, or does it affect the angle of pull?
Most of my equipment is John Deere, but I love my Oliver plow! I also have an 880 Oliver so I have a warm spot for that green as well. I'm always on the lookout for a nice 1655 or 1755 to put on the haybine.
Thank you again for your information, it was most helpful!
