How do I Increase the Horsepower on John Deere Tractors?

by John Gregory

Given the unpredictability of weather, a volatile economy and tighter government regulation, today’s farmer is always looking for ways to be more productive with less investment. Increasing the volume of agricultural output normally requires spending on larger tractors and implements, the return for which may not immediately materialize. Alternatively, improving the power and fuel efficiency of a farm’s present John Deere fleet minimizes the financial risk taken to expand the harvest. Adding horsepower (hp) to the tractor engine will facilitate this expansion.

Step 1

Assess your horsepower requirements to determine whether engine or tractor replacement is off the table. Rule out doubling hp, for example, without replacement.

Step 2

Check the engine air filters, replacing them at the recommended times. Install maximum flow filters if presently absent, as impediments to air flow can reduce engine performance up to 15 hp. Attend to the exhaust manifold in like manner.

Step 3

Install a John Deere, or compatible, turbocharger, which will push a greater concentration of air through the engine cylinders, thereby improving the horsepower capacity up to 50 hp.

Attach a chip tuning box, or power box, to the diesel common rail pressure sensor, which regulates the pressure from fuel tank to pump. Adjust the device so that the sensor is allowing for greater thrust, which can raise hp by 25.

Items you will need

  • Chip tuning box
  • Maximum flow air filter
  • Turbocharger
