We have a good engine which we know well. It could power hydraulic pumps and have a huge heavy system around it. It would not be our nimble Farmall or # series anymore. These tractors need a little more torque at low ground speed and that is the way it is. Torque multipliers are known to solve that problem but they increase the torque before the clutches and standard finals. What we need are units which bolt to our shafts hubs and bolt to our wheels. There are so many units which don't appear as tractor parts, someone has done this.
