How do you calculate drawbar pulls?

To find the drawbar pull (DP) of a vehicle in pounds, you’ll need to multiply the torque of the vehicle’s motor (T) in inch pounds by the gear reduction (R) (including the axle and transmission) and divide that number by the radius of the drive tire (r) in inches.

What is drawbar HP on a tractor?
