whatis the difference between a farmall B and a BN

Tom Fleming · Dec 7, 2011

About 8 inches........

Seriously, the "N" in BN is for narrow.

I believe the axles are 4 inches shorter on each side.

The axle units on each side of the BN are 4 inches shorter than those on the B. hence the tractor is 8 inches narrower. The BN uses the same length units as the Farmall A uses on the right-hand side. The A has no axle extension on the left-hand side. The BN seat support attaches to the end of the axle as in a Farmall A whereas in the Farmall B the seat support is 4 inches inside the end of the axle.

As stated, the width of the rear of the tractor is what makes it a B or BN. For a quick check, look for a gap between the right hand seat bracket and the right fender. The picture shows a B. The BN will have no gap. This one has an afermarket seat on it but the gap is still there. I don't rely on serial tags anymore.
