I was so excited to find a plow that was from the same time period as the 165! Did your 155 have Multi-Power?
Oh by the way, did you decide to buy the book on the MF 100 & 1000 series? I know it talked about the MF 155.
Not yet, that will be done soon I think.
Our 155 had a four speed transmission with a Hi/Lo range, no Multipower. I've got to get into Dad's pictures and see if I can find some of me on the Massey, I was on it every chance I had. One funny shot occurred while the tractor was still new, my sister and two or three friends were all wearing sun bonnets and climbed up on the tractor and Dad took a picture.
