Great product for the money definitely great for fallen trees and little trees that you can't get with a brush cutter. just dont man handle it too much it will cause the engine to over heat and you'll have to wait 2 hours or so till it cools off to be able to use it again. If you can find a chain that stays sharp longer I'd recommend it helps out alot and you won't have to sharpen the chain as much but do sharpen it it helps with cutting down thick tree trunks.great product in all no real complaints about it

Worked well, until the lower mount for the front handle failed. That attachment is, amazingly for Ryobi, merely a sheet metal screw through the handle into the plastic housing of the saw. The failure occurred after only 1/2 gallon of fuel used. It's had occasional use for about three months. That mount comes under a lot of lateral stress when felling a tree, and apparently it simply pulled out against the threads and stripped them, because now the screw will not tighten. It's possible that the threads were stripped during assembly, but it is an inherently weak arrangement. I bought this saw for three good reasons: 1 - very positive long-term experience with Ryobi tools, 2 - I own and heavily use a Ryobi Li-ion cordless chainsaw. That tool is very effective and solidly made, which I naturally expected to be the case for their larger gas version. 3 - the low price for a fairly powerful saw.

Powerful but lightweight
[This review was collected as part of a promotion.] Bought this a month ago as I had been given some oak trees to cut up for firewood. I knew that my old 16 inch Poulan would not cut it. Yes read lots of reviews on lots of saws. Had used Husqvarna and Stihl as a volunteer firefighter but couldn’t justify the expense. Took the Ryobi out of the box, added fuel and oil, adjusted the chain, fired it up and was immediately impressed with how the Ryobi cut through those 24” diameter green wet oak trunks. Cut nearly 2 cords without a hitch. Even more importantly with the lighter weight of the Ryobi my arms, shoulders and back didn’t feel as though I’d been stretched on a rack!!

Great Little Saw
[This review was collected as part of a promotion.] Three months ago, I was debating whether to go with a lesser known brand with a lot of good reviews, similar price but it's length and cc's were slightly more than this 20" Ryobi. Although I had read and saw positive reviews for this saw and I know and trust the brand from having had a couple of their other power tools i decided that going a little bigger while saving only a couple of bucks was the way to go....huge mistake that ended up costing me more in the end. I have about a quarter acre of wooded property at the back of my house and little by little we've been cutting and limbing trees trying to expand our limited backyard by a couple of feet and really also just trying to get some more sunlight on the property so we could enjoy it more. I started this project with the larger saw and from day one, it labored cutting 8"-10" thick trees which I assumed it was normal but then after the 5th tree it also started to leak oil, stalling and i didnt feel as tight. I knew it wasn't the right saw for the job so i put the job on hold, fast forward to last month and my son gave me a gift certificate for Father's Day so i decided bite the bullet and buy another saw, but this time i think i got the right one! As soon as i saw the case and then took it out, i knew it was just so much better quality. It came assembled, instructions were simple and even had a fuel additive included. My wife and I took a day off, rented a 50ft bucket lift and put the Ryobi to work. It started right up and man, it was cutting wood like butter! I coulnd't believe how effortlessly it performed compared to my other larger more powerful saw. It went all the way through a few 12" trees with getting jammed. In total we cut 6 trees and tens of thick tree limbs and branches with no issue. Applying the tension and cleaning afterwards was easy, IMO it felt better, safer and solid...overall just a great little chainsaw that I wish I had purchased from the get go.

I had gone to Home Depot a few weeks ago, fully expecting to spend over $350 on an Echo chain saw...
I had gone to Home Depot a few weeks ago, fully expecting to spend over $350 on an Echo chain saw, to replace an '80s Poulan 3400 that's really starting to show its age. Home Depot didn't stock the CS-490 I'd wanted, so I started looking at what they did have in stock. It was then that the Ryobi 18" 2-cycle saw caught my eye. I decided I "had" to have the larger 20" saw, which Home Depot also didn't have in-store, so after some research and some internal debate, I bought it online for $150, during the last few hours of Home Depot's Labor Day sale. At the same time, I also bought a "better" Oregon chain online, to fit before my saw's first use, as I didn't think I'd have much use for the "safety chain" I knew it was going to come with. I'd also already decided to go against Ryobi's recommendation of using 50:1 fuel, and bought a small can of 40:1 fuel instead. I figured I'd burn through that, before moving on to mixing my own fuel. After unpacking my new saw and going over it like a little kid with a new toy, I read through the manual. I was a little disappointed in the fact that the chain oiler isn't adjustable, but I thought, "If it works as it is, who cares?" After finishing with the manual, I loaded my RY5020 up with fuel and bar and chain oil and attempted to start this thing for the first time. I followed the starting instructions to the letter and within 4 pulls, it was up and running! Right away, the sound of the saw impressed me. It seems to have a deeper, growlier sound than the other saws I own (the Poulan 3400 and a Husqvarna 261). I let it idle until the chain started to move slightly, then I blipped the throttle to take it off high idle. At that point, I felt it idled nicely and was very responsive to trigger inputs. Within a few hard revs, I noticed the chain was nicely coated in chain oil. I was ecstatic! I couldn't wait to use it in the woods! Three days later, I was on my property, clearing brush and smaller diameter trees from my dirtbike/snowmobile trails. I used the saw on and off for over 4 hours and it never failed to impress me. At one point, I refilled the saw with fuel and chain oil, even though neither had run out. I'm sure my old Poulan would have gone through multiple tanks of fuel over that same amount of time! At any rate, after the engine was hot, it easily started in one pull, every single time I went to start it. Numerous times throughout the day, I talked my new saw up to my fiancee, who was helping me pull the branches and limbs I'd cut off into the woods. At one point I said, "This is easily the best $150 I've ever spent!" I would gladly recommend this saw to anyone in the market for a "hobbyist" chain saw. I can't yet speak to its longevity, but I feel like it should last me at least a dozen years or so, especially since I'm using an "oilier" mix than what Ryobi calls for. The saw comes with a 3-year warranty, plus I bought the Home Depot warranty for an additional $18, so the saw is covered for a total of 5 years - just like the Echo. The case it comes with was weird to me at first, but now I really like it. It can be locked shut with a padlock, and has built in places to store a set of files and a spare spark plug (all sold separately). I can also get two 1-quart bottles of oil in there as well, along with a shop towel, the owner's manual, and some little "odds and ends." Anything else I might need while I'm out cutting, I carry along with me in a 5-gallon bucket. I did give the saw a 4-star rating in the features and ease of use categories, because even though you can check the saw's air filter without using any kind of tool, you need a screwdriver to remove it. Also, there's a pre-filter that's supposed to be cleaned after every 5 hours of use, which seems to involve removing the pull starter and a cover situated behind it. Overall, it's a very nice product, and I'm sort of glad Home Depot didn't stock the saw I had originally gone in to look at!

Starts right up , has a surprising amount of power , cuts fast , cut up a tree downed by a storm , and took down a pretty big oak (by residential standards I'm not a lumberjack) and then cut slices of the oak to be painted for crafts by my GF and mother . It's not a professional saw , or it would be 800.00 , but it is a very good weekend or honey do list saw, I highly recommend.

Found a big job perfect for this saw. Two tall palm trees, as you can see. This saw cut through them with ease, and then into 18” logs. Believe it or not both trees were down and into logs in just under 45 min. The saw made easy work of this big job, so happy with the job it did. Blade slide through the trees with the greatest of ease. The tensioning system worked perfectly and the self oiling made it easy. A great tool for the price.

I've had several pole chain saws, and several 14" and 16" saws, so it was finally time to step up to the 20" bar. This chain saw comes in nice quality case, with instructions on the top whan you open it. It shipped directly to me, it suprised no one that it was a chain saw. It even comes with a bottle of oil to mix with 1gal of gas (50:1 mix). You'll need to get some bar oil if you don't have any. The tension adjustment is is on the side of the bar cover and this saves a lot of effort. Once filled the saw was a breeze to start the engine (2 attempts). The 50cc engine seems to have plenty of power, and the chain is oh so sharp. It cut throught a 5" oak log like butter. The 20" bar makes cutting large branches/logs much easier than with a smaller saw. The saw says that it has 3 types of vibration dampening, I was legitimatly suprised that my hands did have that "bee" feel that you normally get after using a chain saw for any period of time. The saw weighs about 10 lbs, it includes a chain break, bumper spikes, tip guard and automatic oiler. It also has a 3-year warranty. I've owned numerious Ryobi tools, all have been reliable, but this is my first chain saw from them, so far I'm very impressed. Can't wait for a larger job to do some real work. And did I mention, I really like the case it come with.
