Description
Our mission is to provide homeowners and small businesses with commercial-quality wood chippers backed by exceptional support. Patriot Products, a small Midwestern business, has manufactured high-quality gas and electric chipper shredders in the United States since its establishment in 1992. Our units are intended to last you a lifetime, when operated and maintained as we suggest. While we continuously strive to improve our products, we still offer parts and support for even our oldest units. Our ultimate goal is to have completely satisfied customers. Whether you’re in your twenties or your twilight years, we have the perfect gas or electric chipper to help you process yard waste! Our products will perform as advertised when operated and maintained per our instructions. There may be a brief learning curve as you begin using your chipper. Don’t panic or get frustrated; message us and we’ll be glad to assist you! Patriot Products offers a 30-day promise of satisfaction for Amazon customers who purchase directly from us. Products must be free of damage and misuse to receive full product reimbursement. We recommend messaging us first to avoid an unnecessary return, as you are responsible for the cost of returning the products directly to our facility. Your Patriot chipper easily turns your unsightly pile of branches into something more easily disposed of, even better, used as mulch. We offer a full line of high-quality gas and electric chipper shredders made right here in the United States. MOST IMPORTANTLY, you’ll get personalized support from a small business that truly cares about your needs. Not finding the answers you need? Just send us a message. Patriot is here to help you find the perfect product. Patriot uses commercial-grade components, so your chipper will last indefinitely if it is properly operated and maintained. Think of it as a family heirloom! Loose, bulky materials such as leaves, pine cones, and walnuts get pulverized, making them much easier to use or dispose of. Not just any engine. Briggs’ Vanguard Series commercial grade engine is renowned for its performance and dependability. It is the heart of the machine and nothing else matters if you can't get the engine started when you're ready to work! The engine is protected by a low oil shutoff switch to prevent accidental damage. The greasable outboard bearing is a key feature in the success of Patriot’s direct drive chipper design. The bearing supports the outer end of the rotor shaft and takes a significant amount of weight and stress off the engine shaft. Less stress on the engine shaft translates into smoother chipping and longer engine life. Patriot’s direct drive design eliminates belts and pulleys, plus the associated structure and covers. One benefit is that no power is lost between the engine and rotor. Even better, it significantly reduces the unit’s size and weight, meaning you get a more powerful chipper that is easier to move, use, and store. Our customers constantly amaze us with their creativity: Got a material you want to try? Message us; we routinely test different materials for prospective customers.

DECEMBER 2019 UPDATE This machine is still going strong. Just used it for about 4 hours over the Thanksgiving weekend. The unit had sat since the fall of 2018. Checked the oil, topped off the fuel and it started on the 2nd pull. Ran like a champ, had no problem handling huge piles of oak leaves and small branches. I really love the mobility of the machine. Maintenance has been a breeze. I use it 2-3 times per year (8-10 hours) so I expect my usage is on the light side. The shred ratio by weight is probably 95 - 5 leaves-to-branches. I change the oil every-other-year but check it before each start and use SeaFoam in my fuel for long storage periods. I am still using the original knives, seem to still chop things up nicely. I purchased an extra bag to allow for extra shredding before needing to empty bags. I stand by my 7 year old review. This shredder does everything I need and does it very well. NOVEMBER 2012 ORIGINAL REVIEW The CSV-3100B arrived in two boxes and took approximately 30 minutes to assemble. The assembly instructions are well written and easy to follow. After filling the B&S engine with fresh fuel and oil it fired up on the second pull. I let the machine warm up for a few minutes before I began to feed it. After nearly 8 hours of use over 2 days here are my pros and cons: PROS: - Powerful machine, has no problems handling 2" dry branches - Easy to move, one side of the hopper has molded handles which makes it simple to tilt the machine back and push/pull it into place - Makes a beautiful shred product. Most of our leaves were very well shredded. The average size was less than a US Dime. - B&S engine fired up without any problems. The pull start requires a nice, steady pull. - Engine throttle allows the user to throttle down the unit when they aren't shredding. Greatly reduces noise levels. - The standard bag is easy to move and unload. Larger bag is nice, but can get quite heavy. - Unit includes a pair of safety goggles. I already own several pairs, but its a nice touch by Patriot to stress the importance of eye protection CONS: - Small branches hidden in your leaf piles can cause "bridging" issues in the feed hopper, no tool is included to help clear clogs - Branches must be fairly straight to feed into "cone of destruction" (kids name for side feed) - Bag attachment point appears to be a bit "rough." If the bag is not perfectly placed the unit will blow shredded product all around To expand on a few of the cons - unclogging can be a challenge at first. I found that using a straight piece of wood (in my case a 1.5" dia branch) to stir the material at the point the feed hopper narrows worked very well in clearing the hopper. The unit creates quite a bit of suction so the issue was usually related to small branches in the leaf pile bridging the opening and causing a backup well above the actual shred point. I also noticed that feeding it a bit slower helped greatly reduce this issue. The area that the bag attaches to the machine needs a bit more work. I'm looking into fitting it with a rubber or plastic baffle/collar that the bag would fit over. This should make operation a bit tidier and result in less shredded material being blow around the unit. The Patriot CSV-3100B is not perfect, but the "CONS" are so minimal that they come no where near negating the usefulness of this shredder. It does exactly what you expect it to do and does so very well.

I read most of the reviews on this site. I don't agree with any review less than 5 stars for this unit. Surely there's always a fluke that deserves one star. But those I've read either did not know how to operate a chipper/shredder or were too ignorant to know how to form tools to clear the hopper. Patriot Products fabricated a costly tool made from PVC pipe that works great to clear hopper. After purchasing one I found that I could make the same tool for $10 or less; theirs is around $80. Still I'm glad I made the purchase. It makes clearing the hopper a breeze. In the early 70's Craftsman made a chipper/shredder, 8 hp. I used that unit around10 years; clearing this same property. Worked that unit until the valves couldn't hold the pressure. Been here 50 years. This is my third season clearing my property that still looks like an overgrown jungle rather than a golf course. The weeds and pine tree shoots grow faster than my old bones can move. But here I am with this Patriot 10 hp chipper/shredder clearing my ½ acre overgrown jungle to make it presentable. I'm sure my neighbors would show up wanting to go for the hunt if the season was right. By late Spring, I should have this place cleared using this unit. It's quite powerful; much more so than the Craftsman. I put everything in this unit. I limit the limbs to 2½ inches more or less (eyeball). There's plenty droppings from Pine, and Gum trees, including gumballs and pine needles. You want to stop up the hopper? Throw in a shopping bag of pine needles. PVC plunger to the rescue. You use the unit to shove them through, no problem. Honeysuckle clippings shove them down the hopper with the PVC plunger; along with any leaves and brush. With the Craftsman, I used an old 2×4. It did the job. But after a few beers it would hit the blades and wake you up!😖 The PVC plunger is designed to prevent this. It goes far enough to clear the hopper and stops before hitting the blades. If you see the picture of this unit, think PVC pipe and fittings. Easy to make. Very compatible. There is no replacement. Patriot's designed this unit with the center of gravity at just the right point to make the unit very portable. A 10 year old could move this thing (not operate). As to the noise level, There were some complaints. A chipper/shredder without noise is usually off and not working. Even the worthless electric versions make noise. So if those who complain want quiet, don't turn the thing on! 😖 Make your neighbors happy. Aww, they'll probably complain about your jungle! This is a very good unit. A lot of thought went into the design, to make this unit a functional, powerful, portable Chipp/Shredder. I highly recommend.

I spent $500 to hire a tree service to chip up 15 years of brush piles in my back yard. Though that amount is cost effective compared to the price of Patriot Products 3100B Chipper/Shredder; I bought one to eliminate brush piles themselves. It works as advertised making short work of tree branches and bush trimmings. Engine is very powerful with deep, mellow exhaust sound. I just love listening to it. It starts on the 1st or 2nd pull, though pulling is not easy because of the weight of the flywheel/cutter. The mulch it produces is a nice, small size which stays in place and decomposes quickly. It also is very effective at shredding leaves in the fall, shrinking my compost pile and speeding compost production. The major drawback to this chipper is the need for the branches and limbs to be nearly straight. So i spend a lot of time cutting them into straight pieces. So a wider hopper-like feeding system rather than a cone would be nice. All in all, a very good machine and I would recommend it.

I have had this chipper for over three months and love it. I say this despite the fact that the engine would not start when I received it (was a Briggs & Stratton problem and not the manufacture). Received excellent and friendly support from the manufacturer and a local Briggs & Stratton repair shop fixed it (valves needed adjusting) at no cost. After I got it running and got the hang of it (e.g., you are almost always are better off using the input chipping cone rather than the hopper -- this will make sense after you have one) I can't believe what a great job it does mulching. Twenty foot pine trees of < 4-inch diameter can pretty much be feed into it whole with no problem. I have 16 acres (13 of which are wooded with trails) and one of my biggest problems was always the accumulation of fallen/dead trees. Now, no problem, we (my wife and myself ) tow it around the property with a golf cart (would definitely recommend getting the optional tow bar, given that the Patriot is steel construction and consequently heavy) allowing us to spread the output mulch wherever we need it. Definitely would buy again. PROS 1) Unbelievable power, works as advertised. 2) Very sturdy construction. 3) Relatively easy starting for a 10 HP engine. 4) Great Support CONS 1) Instructions somewhat difficult to follow the fist time. 2) You need to be comfortable being a 'shade tree' mechanic to maintain the thing, not a big deal but any owner should be proficient at changing oil and minor mechanical service.

First off, great packing! Packaged in two boxes, it easily arrived in one piece! With plenty of reinforcement in the box, metal straps, and liberal foam, this will arrive in good shape. The unit is very nearly assembled. A few basic tools and about an hour or two should get you up and running. The instructions are very good and, low and behold, there is an extra of just about every kind of screw, bolt and nut! What a novel idea! Better yet, all the parts fit without hassle, when lining up the holes. Excellent job. The unit seems quite robust. It should last. I'm glad I bought the 10 HP model as the brush I am chipping has very hard wood. I find that green, 1/2" branches shred with no problem. If the branch starts out thicker, no problem: I just chip it down to the point where the shredder can take the remainder. It rolls easily enough, but it would be nice to have an ATV hookup built into the unit. The wheels, while made of plastic, seem very durable. I would be very surprised if these ever become a problem. There is no arguing about the quality of the Briggs Vanguard engine. In fact, I bought this instead of the DR because the equivalent model DR had the lower grade engine. I'll tell you what, though, I wouldn't want to try and pull-start an engine any larger that this! I wish I could give it 4.5 Stars. I would take off 1/2 Star because I feel like the shredder hopper opening into the shredding chamber could be slightly larger. It's a bottleneck of sorts. It is a minor complaint, however, and I feel 4 Stars would be unfair. So for now, I give it 5 Stars. UPDATE 6/30/17: After chipping/shredding about 20 hours, my initial feelings are about the same. It works very well indeed. I did manage to overstuff the shredding chamber once so even the 10 horse engine bogged down. Easily fixed, however. Just loosen all the bolts, and pull the cover off. It took me 1/2 hour. A bit more care and I had no further issues. I did order the tow-bracket as it is bit awkward to move by hand. For me, it would be nearly perfect with a larger shredding chamber mouth and a built-in tow bar.

I have about 3 acres of property with mature trees and low growth (e.g., forsythia, etc.). Over the year, there is a steady stream of dead branches, the occasional tree trimming, the occasional tree that needs to be taken down, leaves in the fall season, as well as occasionally cleaning up from storm damage. My goal is to recycle all the organic material and pour it back into mulch around fruit trees and leaf mulch for my patches of berries and garden vegetables. I debated purchasing a chipper-shredder for brush and small branches (~ 3-inch diameter) or occasionally renting a higher capacity chipper-shredder (which would also accommodate larger diameter (~6-inch) branches. Rental of such chippers is on the order of $200 per day and $600 per week. I swayed to the side of purchasing a residential chipper-shredder (on the order of $1,000), as I did not want to see huge piles of brush accumulate over the year and then try to tackle them at one time. Obviously, a residential chipper-shredder cannot handle larger diameter branches, thus, my pile of logs for my fireplace is a little larger. I purchased the gasoline-powered Patriot CSV-3100B Chipper-Shredder in September 2013, which comes with a B&S 10 HP engine. The packaging was secure to avoid damage during shipping. The assembly of the unit took less than 30 minutes, which is essentially installing the plastic hopper and the chipping cone on the unit, filling the engine oil, and lubricating the grease fitting on the shaft. The B&S engine is bullet proof. I have never had a problem in starting it up cold (on full choke) with one pull of the cord. Starting it up warm is equally easy, but the choke has to be adjusted to accommodate warm starting. Having been exposed to commercial chippers that throw material out of a chute, originally, I was not sold on the idea of chipping into a collection bag for the CSV-3100B. When the bag is full, the engine is shut down for the bag to be removed, emptied, and re-attached. The whole process is unobtrusive and takes a minute or two. You should definitely work with larger collection bags. I empty the collection bags into a wheel barrow and then use the wheel barrow to distribute the chipped material. Shredding leaves and thin woody debris is done through the hopper. There is significant suction on dry leaves, pulling the material directly into the flails. Mixing in thin woody debris or damp leaves, however, tends to clog the hopper and it is necessary to use a stick to dislodge the material in the hopper so that it falls through the hopper and into the flails. Unfortunately, I am not always grinding leaves immediately after they fall, and thus, I find myself dealing with damp leaves. I would not use this equipment on soaking wet leaves, as I think you will be struggling with continually clearing clogs from the chute where the collection bag is attached. Even with damp leaves there is build up in the chute where the collection bag is attached and you will have to watch that chute does not become clogged. Also, I find that shredding damp leaves yields buildup of wet material on the walls where the wheel rotates and where the collection bag is attached. To clear this, I keep several branches that I chip through the chipping cone; adding “fiber” to the diet clears blockages and cleans the pipes. The grinding of larger diameter woody debris and branches up to 3 inches in diameter are fed through the chipping cone. The branches need to be trimmed so that they are more or less straight. Thus, one has to keep this in mind while trimming up brush so that you do not have to stop and tend to this step during chipping. There are 2 blades on the wheel to chip branches. When the blades are freshly sharpened, branches are pulled down the chipping cone; one should not have to force or push branches down the chipping cone. If you find yourself pushing branches down the chipping cone to engage the blades, the blades likely need sharpening. The manufacturer says that blades should be sharpened after 8 hours of use; however, I find that the type of wood that you chip plays a big role in how quickly the blades become dull. From my experience, dealing with dead wood or wood that has dried for some period of time tends to dull the blades more quickly. This past weekend, I was chipping for less than 2 hours when there was a noticeable change in the capacity of the chipper to pull branches down the chipping cone. I would avoid trying to chip branches when the blades are dull, as this places unnecessary pressure on the shaft which can ultimately lead to the misalignment and cracking of the shaft. Access to the chipping blades on the wheel is straight forward; it requires removing the 3 nuts that secure the chipping cone to the unit and removing two screws that secure each blade to the wheel. Unfortunately, I do not have access to the equipment or experience in grinding steel blades to avoid excessive heat and maintain the original angle on the blades. I have invested in a second set of blades and accept that I need to visit my local lawn mower repair shop for sharpening the blades. In general, I find myself chipping branches once a month or once every 6 weeks, and I consider it part of the routine to remove the blades and have them sharpened. Thus, the cost of sharpening the blades on a frequent basis should be factored into the routine engine maintenance and greasing the shaft. I am quickly approaching the time when I will need to replace both sets of blades. The cost of the blades is $70 from the manufacturer. In theory, the flails should also be serviced. Accessing the flails is a little more involved process, which I have not tackled yet. I have only been using the flails to grind leaves and thin woody debris and I have not seen deterioration in the operation of the flails over the time that I have owned the machine. Overall, I have been pleased with the operation of the Patriot product. I am accepting of the limitations of residential chippers such as these. It fulfills my need to chip/grind organic material once a month or once every 6 weeks and pour this organic material back into the soil.

We have had the chipper for just about a year and I've waited until now, until I've had some experience with it before writing a review. 1) Assembly: Easy and straight forward. Good directions. 2) Starting: Reliable. One or two pulls at most. 3) Power: More than adequate for brush and small branches. 4) Issues: Once you get the hang of feeding small batches of cuttings there are no clogging problems. Don't over stuff the hopper. It's a good idea to have a 1 inch diameter branch around to push any stuck material into the machine. When the bag fills up, empty it. Very, very, very loud!!!! Hearing protection a must. Heavy. Dragging it around, especially uphill is a chore. We find it much easier to bring the brush to the Patriot. Bottom line: This is a fine machine and there are no regrets. Would buy it again. We have 5 acres and now, thanks to the Patriot, we have no brush piles and lots of valuable mulch. UPDATE (A year later): Still no regrets but a warning. I have experienced 2 jams, one worse than the other. The second required partial disassembly to clear the material. NOT FUN. The lesson: Avoid grass!!! Especially bundles of long, green grass blades. And feed material down the hopper in small batches allowing one batch to be shredded and ejected before adding more. Another problem: My wife loves this machine. I suspect she's cutting and pruning things just so she'll have more material to shred. As for the engine, after a winter in an unheated garage in upstate NY it started with the first pull. Still no regrets.

I picked this one because I don't have a lot of storage space and this machine seemed to pack the most capacity into the smallest envelope. Overall I'm happy with it. It's first job was to chip oleander trimmings. Between pruning and chipping, I was able to fill 6 Herby Curbies (2 per weekend, over 3 weekends) working 4 hours a weekend. Impressions: The motor is top notch. It is supposed to be relatively quiet, but make no mistake about it, the thing is loud! The motor starts easily when cold, not so easily when hot. It has a throttle so the motor can be throttled down when not actually chipping, for instance when emptying the bag. The hopper has a narrow throat and material bridges easily. This is probably my biggest source of dissatisfaction. Have a stick handy for clearing jams. Loosening the jam by lifting seems to work better than pushing it through. I like to use leftover PVC pipes because accidental contact with the flails just breaks off the end, with no tendency to pull the pipe into the machine. The machine does not like wet material. Wet material tends to clog the outlet. You must not clog the outlet as it can lead to a stall with material still in the machine. A failure of this type will likely result in some degree of dis-assembly to clear out the machine before it can be restarted. It does not like dry or dirty material. If you use the thing to chip roots, the knives will become instantly dull (said experiment performed by my spouse). Sharpening the knives requires power tools. Knife maintenance is part of the cost of owning this machine. Personally I've had good results using Grizzly wet grinder. They aren't as pretty as new after sharpening, but they cut almost as well. The exhaust faces down and will burn your lawn. Don't use it on the lawn. If you use it on hard surfaces, it helps to have some heavy blocks. The vibrations will cause the machine to walk around. All in all, I am happy with the machine and it has been quite helpful in maintaining my yard. There is a definite learning curve with this machine. My biggest gripe is the easily clogged hopper which is why it only gets 4 stars.
