4521 FEATURES
Relentless Power
A great chipper needs to be powered by a great engine. Constructed in Mississippi, the 20.5HP Kohler Command Pro CH640 engine provides extended maintenance intervals and fuel-efficient operation with features like:
-
Integrated oil coolers extend oil-change intervals and maintain low temperatures during the entire power range.
-
High-efficiency, heavy-duty air filters provide protection from debris and ensure longer service intervals.
-
Extra-large sleeve bearings support heavy loads in commercial and industrial environments
Dual Blade Rotor with Split Frame
Equipped with a dynamic balanced dual-blade reversible rotor, the 4521 devours a diverse range of tree materials with unparalleled ease. While gravity-fed, the specially angled A8 American-made tool steel blades develop a significant self-feeding effect that dramatically improves the chipping operation.
The innovative split frame design isn't just for show—it's your ticket to swift inspections and effortless debris clearance, ensuring your beast is always ready for action.
Efficient Certified Fuel System
The Yardbeast 4521 stands out with its American-made robust fuel system, designed for performance and environmental responsibility. Here's what makes it exceptional:
-
Fuel Tank Capacity: A spacious 5.0-gallon tank ensures extended operation without frequent refueling.
-
Constructed from HDPE (High-Density Polyethylene) with a Level 3 Fluorination, providing exceptional durability and resistance to fuel degradation.
-
Certified for EPA & CARB emission requirements.
Robust Transmission
Transferring all the horsepower to the blades is what is all about in a chipper. Our dual belt centrifugal clutch -fabricated in Wisconsin- takes care of that, with dual bearing and high friction pads with a thick steel bell to even out high thermal loads, this commercial grade clutch is made to deliver. Belt tension is kept in check thanks to its tension idler arm with dual bearing supported shaft that minimizes power loss while optimizing for the long operational life of the elements.
On and Offroad Towing
The Yardbeast 4521 wood chipper stands out for its exceptional mobility, designed for seamless towing both on and off the road. Its DOT-compliant suspension ensures a smooth ride, handling the rugged terrains of job sites as adeptly as it navigates highway speeds. Equipped with certified highway towing features, including proper lighting for visibility and safety, the Yardbeast 4521 is not just a workhorse in the woods but a reliable companion on the road, meeting all the necessary standards for safe and legal towing.

TESTIMONIALS
I have used other chippers in the past, but nothing compares to the power and efficiency of this machine for its size. It is straightforward to use, and it has saved me countless hours of yard work. I can chip good-sized branches in just minutes, making my yard work much easier and more enjoyable. Overall, I would highly recommend the YardBeast 4521 to anyone needing a reliable and easy-to-use wood chipper.

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.
BRIAN D. / WASHINGTON
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.
EZRA / CALIFORNIA
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.
