I ended up getting the Makita 14” (XCU07) that takes (2) 5ah batts a year ago and love it. I have 8 5ah batteries total now and a lot of cordless tools. My guys are all switching to cordless 10” miter saws and table saws, which I was always committed to corded tools that generally stay stationary, because what’s the point when you have a stationary power supply and don’t need the tool to go up on a roof or on a ladder. Still, their saws run a while on a charge, pretty impressive.
From my experience with the Makita and what I’ve read about the Milwaukee’s (the best reviewed), they beat gas in an off-road rig simply for the ease of use and are very impressive, as have been all of my other cordless tools.
All my subs use Milwaukee, and once they started to replace heavy right angle drills with cordless versions that cut out the second you take your finger off the trigger making them immeasurably SAFER I saw the direction at least my industry was going in.
My impact or baby skilsaw will go all day without a charge. So with the benefit of not cleaning out old gas or packing premix or risking spilling gas, definitely safer and cleaner which is a huge plus. In most of the national forests I’m aware of around Washington you aren’t supposed to run an unmuffled compression engine without a spark arrester anyway. Disagree with the law all you want, still adds to my consideration.
In an emergency situation at my home I have a 35 year old 20” Homelite that starts on the first pull every time and is good to have around for emergencies when the power is down for weeks (which hasn’t happened…yet). I also have plans for a PTO generator for my tractor, so charging tools can be done as well.
If you’re clearing 5 acres, yes, a gasser is a no brainer and you probably better go 40cc minimum, but we’re not really on a clearing land message board. Do you go out on trails looking to clear that much? I hope t hell not, not exactly treading lightly, which should always be the goal.
If I go out with even 4 batteries I know I’ve got a solid 45 minutes of decent cutting ability and I always carry an axe as well, which I got by just fine with that and a bow saw for years and years.
Bottom line, for a vehicle based chainsaw, use what you see as appropriate, but packing a gas saw for a week worth of travel isn’t what I plan to pack when I drive a little truck alreadytight on space.
