How does the mower overload protection work?

To prevent damage due to overload conditions, do not try to remove too much grass at one time. Slow down your cutting pace or raise the cut height.Your mower has built-in overload circuit protection. When the mower is overloaded, the power indicator on the mower will blink orange. The mower can endure a short time of overload. You can slow your speed to reduce the load; otherwise the protection circuit will shut off the mower automatically. Release the bail handle, wait for a few seconds and try again.

Can you confirm exactly how long the reset period is? My mower overloads constantly if I go more than 2-3 days without cutting my thick Bermuda lawn, and the reset time seems to vary from around 2-5 minutes per shutoff.

This constant shutting off is while moving at a snail's pace with a freshly sharpened blade and a clean, dry, silicone-treated deck, and when only removing 1/3" of growth. It easily doubles the amount of time my yard takes to cut, and has become a major drawback of converting to the Ego mower.

Any advice for minimizing downtime due to overloads?

Jennifer, I think David hit upon a very simple idea.  I wouldn't mind a shorter run time to get through some very thick areas.  Very nice idea.  Elegant.

Wait, I don't get it.   First use, my LM2101 mower worked fine for 20 minutes under minimally challenging conditions, then went into flashing orange mode, which took some 20 minutes to reset.  Hopefully, I'll have some additional time to test it, but if it bogs down like this, it goes back to the store.  My EGO LM2101 replaced an old Jacobson 24 Volt mower which slowed down under certain conditions but never wimped out like this unit.

JVA, this post is a year old and it's about the 20" mower. The 21" mower (which is COMPLETELY different in regard to overloading) wasn't even announced yet then!

I'm quite sure we've got more current discussion threads that are specific to the 21" if you search or look around this site. You will probably get more responses from people who have your mower model if you post in one of those.

I now have the self-propelled version of the LM2102SP, and I have not been able to make the mower overload once yet when using the 7.5Ah battery. Do you have the push or self-propelled mower? The 21" push version has a slightly more powerful motor (700w vs 600w in the 20") but the SP has a 1000w dedicated blade motor (not shared with self propel motor) so it is nearly 50% more powerful than the push version.

Also, the battery you use makes a huge difference. While I can't make mine overload with the 7.5Ah battery, the 2.5Ah overloads constantly. The push version typically (perhaps exclusively, but possibly not) comes with a 5.0Ah battery, so it is only middle of the road in terms of load handling.

If you have the push version and are still within the return period, I would definitely exchange it for the self propelled mower. The price difference between the mower kits is less than the difference between the 5.0 and 7.5Ah batteries, plus you get a more powerful (and self-propelled) mower.

If by chance you already have the SP version, I would call Ego support because a well-maintained Ego 21" SP mower definitely shouldn't be overloading that much, if at all!

Maybe you have a defective unit.  If it's not that big a deal to return to the store, if it were me, I'd return it for refund and try another unit.  I wouldn't even bother with calling Ego as there is nothing they can do over the phone to resolve such an issue for you.

Definitely call Ego before returning to the store if you're having issues with any Ego product! We've had people here that exchanged multiple times for something that turned out to be operator error. What a waste for everyone!

Perhaps more importantly, I believe someone said that Home Depot doesn't indicate a return reason for returned mowers that are sent back to Ego for credit. So then they have to blindly figure out what was wrong with it (or anything at all, like if someone falsely claims a mower is defective). If you call Ego before returning then they can make a note of the issue for when Home Depot sends it back.

Not taking the time to contact Ego may cause you to unnecessarily exchange a perfectly fine unit, but also will definitely make things harder for Ego's quality control and engineering teams, which ultimately hurts us all!
