You have lots of acreage, so do I. actually I'm pretty sure you have far more than I do.
I would NOT even touch Ryobi again. Ive given all that **** away. The problem wasnt the tools, they worked well enough, but the batteries are ass when you are doing a bigger job. 1/2 or 1/4 acre people may have different results.
Some aspect of their battery control just doesnt work once you severely discharge the battery or heat them up. Then you cant even jump the battery to get it to charge. I've seen YouTube videos on taking the battery apart and soldering on a wire that bypasses their little mini controller chip in there. Since I had like 8 or 10 of those batteries most of them hardly used, I thought about doing it. But in the end lithium is pretty scary and I wasnt interested in doing.
I had a few pieces of Husqvarna gas stuff too and none of it worked well. I'm not sure if it's the gas mix we use in the United States not working well for their Euro carburetors or what. Just what Altitude said, no amount of winter prep made those thing work in Spring. again people who don't really store tools for the winter probably have never had this problem. Perhaps the problem was I was buying Lowe's grade stuff. Again, Id never buy another. One of their chainsaws is probably the most frustrating piece of equipment I've ever owned, bext to a Husqvarna mower.
I ONLY use Stihl tools now and never struggle with getting it started and working properly. I would pay twice as much for Stihl. They do have some battery stuff but Ive never used it.
For mowers I have a tractor with a Kawasaki that replaced a Husqvarna that I would have gladly burned. I also have a Honda push mower, that has been a champ for over a decade. The Husqvarna tractor rarely lasted say two or three mows until it had to go back to the shop, but it had one of their ****ty early Chinese engines "Kohler Courage". Maybe they are better now.
Dont listen to Earth nuggets who are more interested in their green religion than actually working. I doubt you will ever see a work crew carrying those, for good reason.
