It's all about gear reduction (torque), not horse power. A 72 to 1 gear reduction coupled to a 500 pound, 8 HP gas engine, 4 wheel drive tractor will drag a 2000 pound log up a 20 percent grade. See what will happen with the same engine on a lawn tractor with stock gearing. It will sit there and spin.
