This is going to sound like I'm shilling for the industry. I'm not. But I'm more than happy with the performance of electrics. Gone are the days of 18V yard tools.
The Kobalt mower has sensors. When mowing higher or wetter grass, it speeds up automatically. I sometimes have time slip away and the grass gets a little high but have never bogged down. It does use more battery when that happens just as a gas engine uses more gas when pushed. I have two leaf blowers, the 80V Kobalt as well as the Trimmer Plus blower attachment that fits on the 80V Kobalt Trimmer. The Trimmer Plus has more power and is also much louder. The Kobalt has three speeds.
Batteries are expensive. But I don't have to winterize, buy oil to mix with the gas I also have to purchase. There is no replacing of the little primer bulbs, no smoke, FAR LESS noise, and many municipalities and states have rebates for electric. There are far fewer parts to go wrong and be replaced at some point down the road. Like you, I also use mine weekly though I actually use the blowers for a quick sweep several times a week. I even used the blowers for snow removal this last year. Mostly powder but also if you chipped up surface ice, you could blow under it and it kept flipping up the packed layer and blew off underneath. That came in pretty handy and sped up getting to the car in the morning.
I don't have to burn hydrocarbons past initial production. I also no longer keep gas cans (and gave all mine away) or have to make trips to buy gas, and don't worry about stabilizing gas for the winter. No vapors, no fire hazards, no smells.
Best of all? No more yanking arms out of my sockets trying to pull-start anything. Flip a switch & squeeze a trigger. Ms. UrbanWild also appreciates that one.
The Trimmer Plus attachments I use most are the hedge trimmer, pole saw, and blower. The cost to add those to my Kobalt platform was not as large as buying all the standalone tools. The mower came with two batteries and the trimmer came with one but I bought it when they had a rebate for an extra battery when you bought it. So, I have four batteries that I can use in any of the tools. I also have the blower that iuses the same batteries. Since I have three chargers I can fully charge three batteries in about 20-30 mins. That means if I start with four fully charged, I'd have newly charged batteries coming off the chargers before I am physically able to discharge the ones I could already use. I'm going into my sixth season on my fleet.
Even Stihl has started putting out electric units.
Not trying to sell you, but the industry has been heading down this path for a while. In trade shows it's been reported that some more traditional companies have noted they will be all electric at some point.
The guy who owns the house three houses away from me has a commercial lawn and landscaping service with all the necessary large vehicles, tankers, trailers, pro machinery and tools. At home? He uses the same Kobalt 80v tools I do. In fact, I talked to him about his units before I took the plunge trimmer.
Again, the back mower wheels are a bit wobbly and I will eventually need a string cap for the trimmer. But after 5+ years of constant use that's it so far. The mower had a 3 year warranty. Can't remember what the trimmer had.
. I was using it just a few days ago when I decided that the hottest day of the year (so far) was a good day to trim the hedges (it was not sensible!!!
