My 15 year old gas powered Toro Super Recycler is still going strong. But I secretly look forward to the day that it dies, so I can
upgrade to a battery operated mower. As
@Astro14 mentioned, I will not miss having to deal with stinky gas, changing plugs and air filters, cumbersome oil changes, worrying about spilled gas dripping from the deck onto my lawn. I won't miss the mower smoking after tilting it on it's side to put on a sharp blade. I won't miss having to wear hearing protection.
After my Stihl string trimmer engine wouldn't stay running this spring, I
treated myself to a Milwaukee M18 string trimmer and leaf blower. Although my Stihl leaf blower still works great, the two tool package deal was too good to pass up. I don't miss the 2 cycle tools at all. The M18 string trimmer doesn't drip gas on me when I tilt it to edge the lawn. The muffler doesn't burn me. I don't have to wear hearing protection. No mixing 2 cycle fuel.
Since the Stihl leaf blower still runs good, I would, on occasion start it up and use it instead of the M18 leaf blower. But I do that less and less, as the M18 is so nice to use.
So no, I won't be nursing the B&S on my Toro, trying to keep it alive in hopes of avoiding a battery powered mower. Instead, I'll be giddy with excitement when the old Toro gives up the ghost, looking forward to enjoying a battery powered mower.
Tell your small engine repair man that he better be finding a side gig, because that bubble that he plans on enjoying, will burst.
