Does anyone know what the torque rating on the AHH is? I know it’s 9 hp but I can’t find any info on the torque.

Thanks

Dusty, The Wisconsin AHH makes a maximum of 25.5ft/lbs torque @ 1400rpm. At governed speed, 2200rpm, maximum torque is 22ft/lbs with a rated horsepower of 9.2. If you need a single cylinder Wisconsin engine with more torque do not overlook the AGND, it is a fantastic engine which makes 27ft/lbs of torque @ 1900rpm.

Thanks for the info Chris. It’s on a Gibson model d tractor. I also have another Gibson super d2 with the Wisconsin TF on it. I could never find the torque ratings on either of them.

The Wisconsin TF produces a maximum of 33ft/lbs of torque at 1600rpm. At governed speed, 2600rpm, the TF produces 14.6hp and 29.5ft/lbs of torque. A lot of Gibson tractors used the model AEH engine which looks like an "AHH" to most people but is only 5.9hp @ 2200rpm. The AEH produces a maximum of 14ft/lbs of torque at 2200rpm which happens to be that particular engines maximum governed speed. The later AEHS had an updated camshaft/governor and was able to produce 7.4hp at 3200rpm.
