I will start cutting firewood in the coming months which made me wonder, "what's my best and worst chainsaw?" I'm not extremely picky on brands but my experience with Echo is mixed and is limited to one model with Stihl. Aside from a basic homeowner, inexpensive poulan I've had 3 chainsaws.
My first "farm/commercial" grade purchase was the echo cs590 "timberwolf." Bought it bout 9 years ago (?). My favorite saw. 20" bar and cuts everything I've thrown at it. I've cut firewood: we heat our home with a Lopi wood stove. I've trimmed trees and cleared well over 1,000 cedar off of 70 acres. This saw is my favorite. It's a bit heavy for trimming and clearing cedars.
I wanted a lighter saw so, I stuck with Echo and bought the 4510 with an 18" bar. This saw never ran right. Finicky bout idling. I struggled with it for a few months. My dealer (who is great) tweaked it. Ran a bit better. I even started buying the echo premix fuel. I've always used premix but upgraded to echo's red "something." Somehow, that saw burned up and I threw it away after less than a year. The dealer said water somehow got in the fuel. I'm not sure how that could have happened. Regardless, I never liked the saw so I didn't press it.
I then picked up the Stihl ms250 with an 18" bar. This is a great saw. Lighter than the echo. And, starts a bit easier. But, it doesn't cut as efficient. I use both saws and appreciate them. The cs590 remains my favorite. It just cuts so dang fast and sometimes the weight works for me. Even when I'm sawing cedars horizontal the speed may offset the weight.
I do want a new saw. I'm thinking about a new cs590. What's your experience for best all around saw. By all around, I mean firewood and property mtnce (clearing cedar, fenceline cleaning, even cutting brush and underbrush).
OK, I'll give this a shot. I have used a lot of chainsaws for farm use, not for logging or arborist use, tho.' Here's my experience...
As 5030 said, the best chainsaw I ever owned was a Stihl 028. A younger version of myself heated with wood. I used that saw so much and was so impressed over the years, I traded it in on another Stihl. Worst mistake ever. The closest Stihl size never had the power of the 028. So traded it to another Stihl. And another. Turns out the Germans apparently forgot how to deliver fuel to their engines. And professionals, in larger saws, swear by them. I've got one in the shop, fairly new, that myself and others swear at. And don't tell me to spend time "fixing" an apparent factory problem (from what I read). Still a good, strong saw, when it runs...
I buy from a dealer - next to the Stihls was a pretty orange Echo. I bought it and never looked back. The CS-500P saw (about 50CC). Bought another, too, CS-501P. Both start, and run, and cut wood. Gee, that's what I wanted. Saw an Echo gas Polesaw. Bought it. Use it a lot. After 8 years...it starts, and runs, and cuts wood. You see the thread here. Think the newer 501P has a compression release, but all of these saws start easily.
Here's what I do on farm saws not used every day. I use only Echo Red Armor oil for my mix (it has some onboard fuel stabilizers) and only 89 Octane alcohol free gas. I also change out bars and chains to 2 or 4 inches smaller to get real performance out of these saws (except for the polesaw).
For field use, I use good sharp files and a raker gauge, etc. But...I have to train people that if you touch one of my saws, you sharpen it and fill it up afterwards. Period. But, it takes a little time to show folks the two file system, so I am now using PFERT 2 in 1 file guides (cuts the tooth and raker at the same time). Seems to work well enough, easy to demonstrate, and this is what Stihl is selling with a different color...
Another note...I have two 56V Echo cordless chainsaws with several fat batteries. They go on the truck or RTV when things go to the devil during a storm. For limbing downed trees and cutting 6-10 inch branches, they are great (and I'm not always a fan of some of this stuff). They don't replace gas chainsaws, but make these tasks much easier.
This is just my personal experience. But I am satisfied with Echo for my farm purposes. And you might do some reading on one of several arborist sites for chainsaw reviews. People who make their actual living with a chainsaw...know stuff.
Best of Luck. But buy from a good dealer.
