@@WilsonHayFarms well the good thing about a 1066 is those engines if you try enough you can get them cranking 170.But if the jd has a German diesel in it it’d be a close match.
My grandfather bought a 1942 H brand new and farmed with it for years. We still have it till this day. It's been a great old tractor and we still use it around the house and in the garden. Love and miss you gramp and gram RIP
