Horsepower will be the same at the blade as the other answer you got. Yes torque will reduce, but the rpm will increase and will offset the torque decrease. The formula for hp is hp= torque * rpm / 5252. So, with a 2:1 pulley ratio you have twice the rpm and 1/2 the torque. 2 * 1/2 = 1. The horsepower at the blade will be the same as at the motor.
