One already exists. https://grassrootsmotorsports.com/forum/off-topic-discussion/i-gave-up-on-2-stroke-power-equipment-hello-40v-co/102423/page1/ In fact it's Slefain's fault I now have one, and feel the need to sing praises about it.
OMG!!! I LOVEthis thing! Pull the trigger, it spins. That's it. PERFECT! That's all I've ever wanted any of my tools to do, just work.
Let me start backwards, with the big garden tiller attachment.
My Echo (mantis) tiller decided this spring it no longer wanted to work. The stored dry carburetor gummed up. Taking it apart the diaphram pin snapped off. The replacement carburetor didn't flow gas right. Then the ignition petered out. And finally the starter spring broke. Launching it about 20 feet down the driveway resulted in the throttle trigger breaking.
I marched inside and ordered a tiller attachment. I actually went with the Royobi unit as it had good reviews and was cheaper than almost everything else.
How did it work? PERFECTLY! Far better than my Echo did when it was running, and the Echo tiller was good.
I plugged it into the shaft, walked over to the garden bed, dropped it on the dirt, pulled the trigger. The tines spun, it dug in about 6 inches, and the garden was tilled. You work it like a leaf rake. There is no bouncing, no skipping. It just tills the dirt. It pulls away from you as you relax your arm, and comes towards you when you pull.
It would do the little raised bed in about 30 seconds. By hand that would take me about 10-20 minutes at that depth, depending on how obnoxious the roots were in the dirt. The Echo/mantis would do it in about 5 minutes, and did sometimes bounce into the boarder boards, damaging them.
This thing is almost eerily perfect at the job.
It spins up, the dirt it tilled, the job is done. It took me longer to smooth the dirt out afterwards than it did to churn it up. The roots were no challenge at all to the unit. Nor were the little rocks, as there was zero bouncing. ZERO. Power was absolutely adequate and never was there a hint of inadequacy.
I've used the hedge trimmer attachment a fair bit too now. It drives it just fine. I've used this on the extension shaft so I could trim all around the pond and creek, and without the extension so I could trim some bushes. It powered along just fine, gnawing down any sapling that could get into the teeth, as well all the brush and reeds and such. I was wiped out from the pond while the battery still had some charge.
This is where the lack of heat and fuel and such really shined. Because it's an electric motor and battery I could hold the unit any which way. Perfect for hedge trimming, and trimming vines out of trees. The lack of noise and smoke and vibration also meant it was never blowing in my eyes or making my hands go numb. YAY!
The closest I can come to a negative in hedge trimming is that will the extension pole, it's a little slower spooling up when you pull the trigger. Never noticed any lack of power though. Just needed to give it a second before you swing it into the weeds/reeds/brush.
The pole saw chainsaw attachment was equally glorious. Ever try to old a 2 stroke pole saw up in the air? It's not a pleasant experience. This thing was. Again, hold it anywhere. No heat, no smoke, no vibration, no gas dripping down your arm. Just the whine of the chainsaw attachment and watch it cut the limbs.
Lastly, it's also a fantastic string trimmer. The lack of noise and the lack of vibration mean you can control the trimming with a whole lot more accuracy and ease. I trimmed around the house and the trees and fence without ever having to bump the head to extend the string. All because I wasn't beating it on things, I could finesse my way up to them instead. I really didn't know how obnoxious normal vibration was with a gas type trimmer.
The ergonomics of the thing for string trimmer are spot on perfect for me at 5'5". In the normal hold, the head is perfectly level with the ground.
I'll wait a little while, just to make sure everything stays spiffy. But I fully expect to be selling ALL my 2-stroke lawn tools this spring/summer. Only my big Dolmar chainsaw will be staying.
This thing is wonderful! Thank you Slefain for turning me on to such a wonderful tool!
