When more energy is needed to drive the engine, the chipper will be louder and will require increased horsepower. If this isn't addressed, premature engine failure can result. And, remember that it's important to change your hardware when you change your blades.

Regardless of when you need to change your wood chipper blades, ordering the right replacements the first time is important. The best way to make sure that you have the right blades is to consult your owner's manual. If one isn't available and you're not sure of your chipper's make and model, you'll need to measure your blades.

How to Properly Measure Your Wood Chipper Blades

To accurately measure your wood chipper blades, you're going to need a fractional tape measure and a caliper. In our demonstration video, we are using a digital caliper.

  1. Start by measuring the length of your chipper blades with your fractional tape measure. BeDigital Caliper certain to start with the metal tip of your tape measure to ensure accuracy.
  2. Next measure the width using your fractional tape measure. Again, be sure to start measuring at the metal tip.
  3. To measure the distance between holes in your chipper blade, you'll need to trade your tape measure for a caliper. Turn on your caliper, if it's electronic, and insert the lower (sometimes called outer) jaws of the caliper into two holes. Once the jaws are in the holes, tighten them to get an accurate reading.
  4. Move on to measure the outside of the hole by laying the lower jaws of the caliper flat on the bottom of the blade. Adjust to ensure an accurate measurement.
  5. Flip the blade over to measure the inside of the hole using the upper jaws of the caliper. Insert the upper jaws of the caliper into the hole and extend them to allow for measurement of the entire space.
