Narrowing up B.N. to A Width. Post # 2

1 morgan · Oct 4, 2008

Hey guys: There are two parts to this ? Does anyone know if the A will pull better for tractor pulling than the B. N. because it is narrower. In the 2500 lbs. class if I had the narrow axle, it would weigth maybe 50 ibs. less, so I could put a little more weigth on frt. # 2 I would like run 13.6x24 tires that also weight a little more. Also does an A also use the cast weight on one side? That should be on the right.side as you sit on the tractor I guess. Any help would be great Thanks............

AS far as the rear weights . . . A lot of As were sold with the lighter stamped steel wheel on the left and the cast wheel on the right. Easier and less hassle than having two stamped wheels and adding a wheel weight to the right. At the same time, my neighbor just came into a 1940 A, stamped wheel on the left, cast on the right, and weights on both sides. In general, yes, you want any extra weight on an A to be on the right, to move the center of gravity in that direction and away from the short left side for stability. This would be even more important if you're going to keep the narrow front.

I'm not a puller, but it would seem to me that the extra weight of the longer diff shaft and housing on the left of a B/BN is free weight on the rear. They're not as heavy as you might think, certainly less than the 140# or so of an A/B wheel weight, probably more like 60#. Or looking at it in reverse, you're only eliminating 50-60# by shortening up the left side of a BN to an A configuration.
