This bad boy pretty much will destroy anything you give 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.

After researching all the reviews and ratings of several chippers as a gift for my husband, I finally chose the Patriot CSV-3100B on the basis of so many outstanding reviews. We have a large garden and use organic gardening methods so he wanted a chipper that would take brush, corn stalks, huge sunflower stalks and put it as mulch back into the soil. He had been borrowing a friends large, well known brand chipper but because of the top heavy weight distribution, nearly had a serious accident when they were unloading it from the truck. So I decided he needed one of his own and started the search for the right one even though I know virtually nothing about chippers. The reviews of the Patriot very important to the selection process. My husband is thrilled with it and how easy it is to handle and move since the center of gravity is low. The engine is easy to start, very powerful and produces a very fine grind. He states it's quality produced of excellent materials. We are also pleased it was manufactured right here in the US. He is singing its praises and would recommend it to anyone thinking of purchasing a chipper.

Best service ever by manufacturer.

After receiving shipment, engine would not start. Most likely cause was bad oil level sensor which prevents starting if oil is low. Oil level was fine, but no spark. Long story short, the president of Patriot products personally delivered a new unit to my door and took the other one away. He had me start it and gave me a rundown on operation and maintenance procedures before he left. I've used this new unit close to 20 hours of major chipping and it's fantastic. It eats 2 inch saplings as fast as I can feed them into the chute. Chips are roughly 1/2 inch. Starts on first pull and is easy to push around the yard. Be careful, not to overfill the mesh chip bag or to allow the bag to block the exit chute on the chipper. This will clog the unit and require disassembly of the chipping chamber. If you take those two simple precautions, this thing will run all day without a hiccup. Very highly recommended. One other suggestion is renting one first to try it out. Ask Patriot where to do that in your area. You won't be disappointed and you cannot beat the customer support. I know!

Great Quality, American Made Machine

After seizing the engine on a Troy Built Chipper Shredder due to my stupidity, I was suddenly in the market for a new machine. I chose this product due to the engine size and positive reviews. I own 1.5 wooded acres with a lake and use this machine primarily for leaf mulching and stick chipping. I could not be happier with my decision. The 3100B was easy to assemble, and it runs like a champ. Much quieter than my previous Troy Built model. The thing I like the best is the lower height of the leaf hopper as compared to my previous Troy Built Chipper. When I do leaves, I use my John Deere Riding Mower (x320) with their Power Flow Bagger system. When my bags are full, I pour the contents into the hopper...NOT TO FAST to prevent clogging. Couldn't be easier!!! The mulched debris shoots out from the top of the shredder over a hillside into my mulch pile. After 6 hours of mulching, I never had to rake debris away from the opening!

Solid and well made.

Before deciding to buy this model, I carefully reviewed this and many others to make sure that I got what I needed. This one kept coming out on top. It arrived very quickly (three days), was easy to assemble, and easy to use. I am used to operating the larger Vermeers and Morbarks, so anything smaller just looks inadequate to me, but this powerful machine quickly chews whatever you feed it. It's easy to move it through uneven terrain, and stable while you're using it. It stores nicely as well, by using only a small footprint in the shed. I'd buy this one again if I needed to, for sure.

Great, well made machine!

Bought one of these in spring of 2102. It is great when used on green limbs up to about 1.5"diameter. Zips right through. Surprisingly easy to start but I found out just recently that it doesn't want to run on the side of a hill (probably not safe anyway). It needs to be on fairly level ground. I have about 5 acres with a lot of trees and brush. A lot of oaks and red cedar. As long as the limbs are green it chews right through. It does not like dead limbs but then if I remember right the manufacturer tells you that in their literature. Most of the time, I just blow the chippings out on the ground under a bush. However, the chipper bag is very convenient if you want the chips or need to collect an move them. It also keeps the chips from damaging the turf if you are on grass. About a year after getting the chipper I ordered the attachment that allows you to tow it behind a riding mower. Wish I had done that sooner. I have saved a lot of effort by taking the chipper to where the limbs are rather than gathering them into piles. Great, well made machine!

Works very well!

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.

This is the one you want!

This is it lot more expensive that I had originally wanted to spend, but after using the product, it was definitely worth the money. The simple, and efficient design makes this a real winner. I have had it for only 2 days. I've filled 8 bags of wood chips, and I am impressed. It arrived early in shipping. I started assembling it minutes after it arrived, and found that the company has clearly thought about the assembly process and has very detailed instructions. This will tell you how amazing the product is: everything was easy, except for 2 of the screws that attach the "hopper" to the main body. It was difficult to match the screw holes of the hopper to the main body. I needed to put my phone light into the hopper to see where the hole was (flash light wouldn't fit.. too small). Other than that the assembly was very easy. The 10HP Briggs and Stratton is clearly powerful enough (I wouldn't go for anything less powerful). I had previously rented one from Home Depot to take care of some of the work. It costs more than twice as much (to purchase, less to rent), and wasn't able to do even a fraction of the work. I was originally concerned about not having a neck to output the chips directly into a bin. It turns out that having the bag seems to be better. I am able to take breaks from chipping to empty it, and it gives me a unit of measurement for how much work I've done (I have a lot of trees, and a lot to chip). This machine is amazing. Keep in mind that the chipper knives need to be kept sharp (using any standard sharpening method like a wet stone or grinder). The branches from my trees have a lot of very small twisty turny branches that need to be pushed down the funnel. I've been trying to make do by using a larger branch to push the small branches down. I think I'll purchase the Chipper Buddy to help with the problem.

Tough and Reliable Machine

I purchased the 9HP Briggs chipper in November 2010. I research extensively prior to the purchase of any product as I only want to buy it once. I own a certified tree farm of 43 acres and when I'm out in the field working I want dependable equiptment that produces. This machine has matched all of my expectations. I use it mainly in the fall and winter months when I thin forested areas from the smaller, undesirable trees or when pruning desirable trees. I chip up the unwanted limbs and small trees and use the chip as mulch in an appricot orchard. On my farm nothing is wasted. Niether is my time or money on inferior products. This is an exceptional machine, well worth my money. It is well made and very reliable. I follow the maintenance schedule per the directions as I do with all of my machinery and it has done a great job. It was a great investment for my needs in utilizing unwanted forest litter and recycling it to productive use. Dr. Michael Deckert

Great product and responsive company!

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.
