  • 1935 John Deere B smoking alot - This B really blows blue smoke when you goose it. I regret tearing it down further when I had the head off to replace the brass pushrod tubes and head gasket. This tractor sat for at least 10 years the guy said I bought it from. At least that's the story he got from the PO before him. I'm wondering if just the rings are stuck in the pistons. Any body have any luck running Marvel mystery oil mixed with the gas to loosen up rings. Other than that it runs good. I have no way of knowing if it ha ...
  • Early John deere B Tappet Oil line - A 1946 John Deere B came to me partially refurbished. A Previous mechanic (who is unknown to me, as this tractor has been thru two previous owners) had used 1/4" OD copper tubing from the oil pump thru block and head, which terminated with a compression nut where it connected to the tappet oil supply. My question concerns the transition from the block into the head. What was the factory original connection? It would appear that the two faces should over lap the holes so the oil would pass th ...

I recently picked up my grandpas 1948 B and want to restore it and bring it back to its old glory. Got it home, and surprised to find i had not problem cranking the engine, so that was good news. After doing some minor maintenance in order to get it ready to try to start, i found that my magneto was cracked and completely corroded inside. I was able to relocate a used magneto that stated it had spark so i purchased it. ...
  • B with 50 pistons - I recently bought back my dad's 43 B that he sold many moons ago, and the guy I bought it from said he added a Heisler head and cast 50 pistons. I still need to pull the valve cove to confirm Heisler is in fact in play. My question is: why use a 50 piston? What's the benefit? I am assuming it is just bore size, so why not just use a larger B piston?

    Today's Featured Article - On the Road with Dave Gohl: Tractors and Farming - by Dave Gohl. I never thought I'd live to see the day, when I could call myself a farmer. What allows me to say this? Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens.
