The horsepower requirements for a John Deere 430 Series baler are at least 50 horsepower. Tractors and implements starting at 50 horsepower are labeled as Category 2 implements.
Identifying horsepower requirements for any tractor requires you to calculate the PTO, or power take off rating needed for any attachment. Often, the power available to the power take off is less than that of the engine's overall horsepower.
Using a 50-horsepower John Deere 430 baler, the maximum produced bale weight is 1,400 pounds.
