About the Patriot Products CSV-3100B Wood Chipper Shredder

Have you heard of the CSV-3065B? Because the Patriot Products CSV-3100B Wood Chipper Shredder is its younger, hotter and wiser version.

This is the perfect machine if you have a lot of trees in the backyard. The machine can go through any kind of organic debris in no time. 

Let me elaborate

For medium to large yards, a 6.5-horsepower engine is good enough. But this baby runs on a 10 hp engine. 

This means that the machine has real bite.

It is not a surprise then

This wood chipper shredder can reduce waste through a mulch ratio of 20:1. This means that for every 20 bags of debris that go through the machine, only a bag of mulch or chips will come out of it. 

Isn’t that amazing?

The average reduction ratio is between 10:1 and 15:1. 


The engine can be used for commercial purposes, too. 

The engine is also Briggs & Stratton Vanguard. 

Lady pruning leaves

What does this mean?

Vanguard engines by Briggs and Stratton are robust and high-performing engines. They are manufactured with premium quality in mind. 


You must know that Briggs and Stratton is really about power. The brand has been producing engines for over 100 years and boasts over a million customers worldwide. 

It doesn’t get better than this!

Let’s continue

So what does that kind of power do? Well, it makes for heavy-duty chipping and mulching. 

If you have a branch with a diameter of around three inches, don’t worry about it. This machine can turn it into chips without much problem. 

You can easily deduce:

If wood is not a problem then processing leaves will be such a breeze. 

That is also due to the y-hammer system built in the machine. 

The Good

This machine is not the cheapest one in the market. But it also proves that you really have to pay for premium quality. 

And premium quality is exactly what you will get from the CSV-3100B. 


The machine could go through any organic debris without much problem. Of course, there is a limit to its maximum capacity and that is three inches in diameter.

That is not bad at all!

In fact

A lot of wood chipper shredders could only handle less than two inches in diameter. 

The large maximum cutting diameter also means that it would be easier to process thin branches that are irregularly shaped. 

This way

You don’t need to break them into smaller pieces for easy processing.  

With that in mind

You can also see that the hopper is quite large in this thing. It measures 16 by 14 inches. 

Just like the CSV-3065, this baby also has a seven-inch chipper. There is no need to break branches with offshoots into individual things. 

Not only that

The power in this machine is great for hardwood. So even if you don’t have a large yard but it is home to some hardwood, then this machine is more practical for you. 

Examples of hardwood trees:

  • Alder
  • Balsa
  • Beech 
  • Hickory
  • Mahogany
  • Maple
  • Oak
  • Teak

Here’s another advantage:

The machine has a high RPM or revolutions per minute. This is in reference to speed. 

That means work can be done in no time at all. 

You know what else?

This machine is so easy to assemble. That is important for a lot of people. 

Plus, it can start quite easily–one pull or two and it is good to go!

Let’s talk about the parts!

The rotor contains two chipping knives that are made of high-quality steel. Now that is important because despite the power of an engine, if it is not complemented with sharp and efficient blades, wood chipping will not be effective. 

The blades are tough and treated with heat so that it will be resistant to wear and tear. 

Yes, folks!

The machine is built to last for quite some time. 

To add to that

The product features and outboard bearing that you can grease for lasting performance. Technically, this bearing supports the rotor shaft. 

What happens is the engine shaft will take on less weight, hence, will be less stressed. 

If that is not quite clear

It only means that it helps the engine have a longer life. 


The product comes with a standard collection bag. The machine is really designed well as it has a side discharge that is more convenient when it comes to the collection process. 

Cleanup becomes so much easier with the bag that comes with this Patriot Products CSV-3100B.

The Not So Good

We have repeatedly mentioned how powerful this product is with its 10 hp engine. Now, with great power comes great–size!

Yep, this machine is quite large and understandably heavy, too. 

So the downside?

Going up the hill is quite an uphill battle. Yes, the product has a pair of wheels, but the engine doesn’t drive itself. 

The product weighs 139 pounds.  

You know what else?

The machine is also quite loud. Wear hearing protection when you use the CSV-3100B. 

You should also know

That working with wet debris has its own little challenge. There is a tendency that the shredder will clog up when you feed it wet debris. 

You have to push the product down with a stick or paddle. 


Don’t feed it wet materials. Surely shredding can wait a day or two.

Price - 88%


Powerful and highly efficient!

That’s quite the machine, right? Patriot Products certainly knows how to make efficient outdoor power equipment.

How do you clean the wood chipper?
For the chute or hopper, you can use a brush or dry cloth to clean them. The same can be used to clean around the muffler. Make sure there is no debris left in the wood chipper so that the machine will not bog down. 

How often should you clean the wood chipper?
Ideally, you should clean it after use. But we don’t always have the luxury of time or the energy to do so especially after cleaning the yard. You can do the cleaning after eight hours of use.  

What are the other maintenance activities needed for the wood chipper?
If it is a gas-powered machine like the CSV-3100B, you definitely change the oil after eight hours of use. That is only for the first oil change. After that, you can change it every 50 hours. You also need to lubricate the moving parts every eight hours of use.
