Well, for real chainsaws, 2 stroke can not be beat period.
I can’t even think of a battery that would work with my Husky 395XP or Stihl 044.
Unless they come up with an electric car/truck with a 6 or 7 speed manual transmission, I ain’t biting.
Batteries will never match the energy stored in gas/diesel.
My dad bought an 044 Stihl Farm Boss in the 1970s. My older brother still has it. I always found it too heavy for me.
I bought a Stihl 026 in 1990 when I bought my first house. I blew the piston in it March 2020. Right during the height of covid. It took over six months and me complaining on a Stihl Facebook post to finally get the replacement piston & rings at my local dealer.
I bought a Stihl battery operated chainsaw when my 026 was busted. It takes the same battery as the previously mentioned Stihl hedge trimmer. It is great for trimming branches. It rips through anything up to about 5-6” inches in diameter. So, when I dropped a (16” DBH)maple tree last spring I used the smaller battery saw to de-limb the log.
I also just used it a couple weeks ago for trimming all the saplings along the old skidder trails behind my house. All those 2-4” diameter trees that curve in to scrape the side of my tractor cab.
The nice thing about the battery saw is that it is light. I can hold it up above my head with one hand. Then cut branches up to 7’ off the ground without a pole saw. I also feel more confident climbing up into a tree with that saw because as soon as you let go of the trigger the blade stops. So, it is a lot harder to cut your leg off!
So, unlike a gasoline engine that you start up and keep running. The battery saw/trimmer stops when you let go of the trigger. The ONLY time it is running is when you are actually cutting. So, IF you buy the biggest battery in the series(I have two now) it will last to finish the entire job.
When I used it for tree trimming it never ran out of power. When I use the hedge trimmer I have never even close to running out of power. The only time I have run out of power and had to switch batteries was when I cut down the 16” dia Maple tree. Again, using the battery saw to trim all the branches.
Here is the list of equipment I own and have experience with:
Massey Ferguson 37HP turbo diesel cab tractor
Landpride 72” finish mower
Bush Hog 5’ Squeeler
John Deere LX 255 riding lawn tractor with 15HP Kohler/ 42” deck
Honda 20” snow blower (4 stroke)
Toro 16” snow blower(2 stoke)
Stihl 026 chainsaw
Echo straight shaft string trimmer(2 stroke)
Stihl FH80 straight shaft brush cutter with bicycle grip
I have two of these. I got one for free at the dump.
Troy Built 4’ sickle bar mower(bought for $50 at a yard sale) has a 5HP 4 stroke B&S engine. Great for maintaining trails.
Stihl MSA 120 battery chainsaw
Stihl HS50 battery operated hedge trimmer
2012 Toyota Tacoma DBL cab long bed pick up(bought new)
