Detailed explanation-1: -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.

Detailed explanation-2: -Drawbar power (Dbhp) is power measured at the point implements are attached to the tractor, drawbar or 3 point hitch. During tractor testing a load cell is placed between the tractor and a load. The drawbar pull and the speed of travel are recorded and used to calculate drawbar power.

Detailed explanation-3: -Drawbar power is the power transferred through the drive wheels or tracks to move the tractor and implement. You can estimate Drawbar power by multiplying the PTO power by the appropriate value from the table below: Tractor Type.

Detailed explanation-4: -DbHp = F × V 375 where F = Force (lb); V = Speed (mph); 375 = Units conversion constant. This equation is derived by modifying the standard power equation.
