Thanks. My grandson has pulled this tractor for the last six years or since his eighth birthday. We used to pull classes around 3000 lb. We have to pull 4000 lb. here and if we cannot keep the RPM up we pull down. Do you know what the ratio change is?

Hey Andy i was thinking about putting the 140 gears in my B but putting them in where 3rd and 4th would be. That way I would have something for a looser track.
But I only got to pull 2 times this summer!
Did you check with Murphy's about your Crank shaft problem?
