How often should wood chipper blades be replaced?
There is no fixed replacement cycle for wood chipper blades; it mainly depends on the usage scenario and maintenance:
If processing softwood (such as pine), using alloy blades, and operating for 4-6 hours daily with 1-2 sharpening sessions per month, they can typically last 1-3 months. If processing hardwood (such as oak), with high usage frequency (more than 8 hours daily), or using blades made of inferior material (such as ordinary carbon steel), they may need to be replaced every 2-4 weeks.
Maintenance: Regularly cleaning and lubricating the blades, and adjusting the blade gap promptly to prevent rust and dust accumulation, can effectively extend the blade’s lifespan. Operating the chipper correctly, avoiding overloading, and not cutting materials beyond the blade’s capacity can extend blade life by 20%-50%.
Without maintenance, the blade surface will rust, wear will accelerate, and if the cutting edge becomes dull and is not sharpened in time, the blade’s lifespan will be greatly shortened. Blades that would normally last a year may become unusable in just six months.
