commercial chipper reviews

I have been using my 4521 for over a year now, and it has been an absolute game-changer for my yard work. This machine is incredibly powerful and efficient, and it makes quick work of even the toughest branches and yard waste. It is also very easy to use and take care of it, which is a huge plus for someone like me who isn't exactly a handyman. I would highly recommend this chipper.


Read on the customer reviews about the Yardbeast 4521

I got the commercial 4521 chipper. I had about 100 trees to cut down varying from small to large. I put most of it through this chipper. Having the higher the 20.5 horse power compared to other 5" chippers at 9-13 HP saved me a TON of time. You can put logs bigger than 4.5" through it but you need to cut them short to not overwhelm the engine.


tree care business leaves commercial chipper reviews

The build quality of the Yardbeast 4521 is outstanding. I got mine the CRX engine. The chipper feels sturdy and durable, which gives me confidence that it will last for many years to come. Took me a little to get used to the chipper engaging right after startup. Overall, I am very pleased with the chipper.
