i love my EGO mower, i bought the trimmer and blower too. i've mowed probably 10 times this summer (bought the mower may 2015) and the last 2 times i've used it on moderate grass height (probably about a 5 setting) being cut to 3 the mower would flash yellow and die.  i can start right back up but dies again cutting the grass in the same fashion.  i made sure everything was cleared in the blade area and chutes (i tried mulching and bagging and both failed) and i've tried 2 different fully charged batteries.  what can i do to fix the problem?

Hello Jack,

Going from a level 5 to 3 means that your grass was trained to grow at the higher level, and is probably thicker at level 3.  Some factors that affect cutting performance

  • Dull Blade (Sharpen often, world of difference)

  • Wet or Damp grass blades

  • Overgrown grass

  • Type of grass

I would recommend sharpening the blade to a razor sharp cutting edge, and see how the cutting goes.

dry, even scorched grass, not overgrown or overly thick.  i couldn't tell you the type but i live in central NJ.  i haven't sharpened my blade yet but its not even 4 months old with pretty little use ( i have 2 babies and don't mow as often as I'd like at times)   i normally cut at a 4, i tried going to 3 but it kept dying on me so continued my lawn at a 4 with a few areas that i had to "lift" the blade up a little to keep it from staling.

hi Jack, four months is really stretching it for this blade. These blades are thin and made of soft metal, which tends to Dull rather quickly. I can't go more than two cuts without having problems cutting, related to the dull blade. My grass is really thick, with the blades. Try sharpening your blade and see how it goes. Take care.

I agree with SCDC, it sounds like you probably just need a sharper blade.

I recommend buying a new blade and swapping it out for your current blade. That way you can sharpen your full blade at your convenience and have it ready and waiting when you need to sharpen the new blade. It's easier to swap in a blade that's already ready than to remove, sharpen, and reinstall before starting (or resuming) your mowing.

I had the same problem today. Cleaned the whole thing so nothing could block the grass from getting into the bag... didn't work.  Sharpened the blade... didn't work.  Realized that the handle locking clamp wasn't clamped to the arm... clamped it, Problem solved. WE
