The maintenance of it period the blades. Of course, had to be replaced now that could be sixis.
I don't know yet but mine were more replaced several times of course, you can sharpen them if you want to, but that's time and maintenance plugs had to be done couple times And the air filter had to be done oil had to be changed. Not big things and then of course, gas. If you really want the mower to run well, you need to run it with high-octane. And with something with no ethanol. In it. And at $4 a gallon in gas. Probably spent about 40 bucks a year. Probably 10 gallons for me to mow my lawn. So over 10 years that's $400 in gas.
Over 20 years $,800. Well, there's your battery replacements. Now your yard might be smaller than mine until it might not be that big of a deal, but if it's smaller, that means your battery is also not going to wear out as fast.
I mean, have you had issues with your ego batteries? I haven't and i've had ego now for about eight years
