After using your wood chipper for a while, you may start to notice that it’s power has been lagging or that it’s chips are rougher than usual. One reason for this may be that the blade has grown dull over time, so it is time to replace it with a brand new one. This can be a fairly simple task to complete, but it is important that you are careful, as rough handling can actually damage your chipper.

Step 1: Make sure that the PTO shaft is in neutral (this means that the engine is out of gear) and that the chipper’s spark plug has been removed. You will need to remove the inspection plate to locate the blades.

Step 2: Unhook the spring, then put the feed roll in its maximum position and block it in place. Take an Allen wrench and use it to remove the bolts from the side of the wood chipper that holds the chute. If there are any bolts on the other side, you will need to remove them with a socket wrench.

Step 3: Remove the blade and give the hole where it sat a thorough clean. You can then put a new blade in or take the old one away for sharpening before returning it to this hole.

Step 4: You can then replace the bolts that you removed in step two and screw the inspection plate back into place. Start the chipper to ensure that it is working properly.

When you are replacing the blades in your wood chipper, it is important that you wear the proper protective gear (including safety glasses, ear plugs, steel capped boots, and so on) and that you avoid wearing loose clothing. This will ensure your safety whilst performing a potentially dangerous task.
