If your engine is gas-powered, check that the fuel is full before starting, and for electric-powered, check the cord to make sure it is not torn or damaged from anywhere.

When starting the chipper, feed it a mixture of dry and green leaves, and use a long stick to push down anything large that is resisting to go down.

Types of Woodchippers

Types of Woodchippers

There are three main types of woodchippers too that are the best. 

  • Drum Chipper – This chipper’s blades are set at regular intervals and can perfectly chip down a huge load of lumber, but they are quite large and powerful.
  • Disk Chipper – This chipper has a vertical disk that cuts the wood pieces into a 45° angle. But a huge amount of lumber can slow down its process.
  • Screw Chipper – This chipper contains a rotating, large, moving screw to cut pieces, in a perfectly uniform size. But, if you want to have a different size, you will have to change the blade.

There also are two types of engines that you can use – Gas-powered, and Electric-powered. Both are equally best; it is your choice whichever you wish to buy.
