Cyclone JD B compared to a regular B

Ckluv · Oct 27, 2008

I have a 1950 John Deere B that i restored from the ground up. We found it in an old corn crib with the motor locked up. The drawbar is nice and perfectly round and not even oval shaped. I dont think its hardly seen an implement. We had everything apart, sandblasted and painted. First tractor I ever restored and man did it turn out nice. The kid that I was working with said it was a "Cyclone B." Is there any real difference? Whats the story behind this? Thankyou in advance!

The cyclone refers to a change in the intake manifold that allows the air fuel mixture to swirl more as it enters the cylinder. It suppsosedly was more well mixed allowing for a better burn.

There is an (eyebrow) over the intake valve on the cylinder head inside the combustion chamber. This was supposed to swirl the air-fuel mixture to give a better burn and more pep. I hope this explains what you want to know.

More of an advertising gimmick used to describe the B's made for the 1948 model year with the pressed steel frames.

Funny thing is the cyl. heads were the same clear back to 1941.
