I really like the idea of a cordless electric lawnmower, but the cost is so prohibitive. My corded electric mower I got for cheap over a decade ago is still going strong.
I have one. The cheapest Ryobi model. It works great.
My yard...s are discontiguous. The front yard is fully separated from the back yard by my house, with only a narrow alley in between that and my neighbor's house, and the back yard is fully enclosed with a fence. Then we have the "way back" behind my garage and shop, the forecourt to which is completely paved. Many obstacles are in between. Getting an extension cord out to all three locations would be a monumental pain in the ass.
If you need batteries, just buy the knockoff ones from Amazon. They're fine. The "brand name" Ryobi batteries aren't any less shit, but the price they try to sell them for is beyond audacious.
So… does that store only sell Stihl tools? Or, do they just order their tools by brand rather than type? Because if so I need to find them and tell them how angry their store makes me.
Stihl typically does their own displays. You can't mix other brands into their products. They have strict rules on pricing and promotion. If you don't follow their rules, you can't sell their products. If you go to any store that sells Stihl, you will find it set up in a similar fashion.
