EGO 56V 50cm (20”) Steel Deck Self-Propelled Lawn Mower Won't Start

Just bought this lawn mower and did my backyard and it worked fantastically. I had it set to height 5 but the grass was super tall (waist height) due to my petrol mower being broken down for some time. But it got through it easy. I am close to saying this is by far the best mower I've ever used in my life. But then I then wanted to recut at a lower level. I recharged the 7.5a battery to full charge and tried to start the mower but it won't start, self propelled feature not working, and also I tried to use the lights button but the lights don't come on.

There is no warning light.

The following troubleshooting was done:

1) Ensured 7.5a battery was fully charged. Shows 4 green lights in rapid charger, holding power button on battery shows green light. Tried 2.5a battery fully charged from another ego product, which I confirmed worked in blower, but not working in lawn mower.


2) Mounted battery until clicked - tried about 10 different times. Checked contacts were clean and no debris in the battery compartment.


3) Too hot ... can't see any orange light indicating overheating. I left for 30 minutes and retried, still no go.


4) Checked handle is fully extended, and locked clamps. Retried a few times.

5) Handle is in one of the 3 operating positions, tried all 3.

6) Checked there is no debris in mower, and blade can move freely. Tried with mulcher attachment and empty bag. Tried starting on pavement where there is no grass under blades.

Any further recommended troubleshooting steps?

Malcolm, did you depress the green button, then pull the handle to start?

On my 1st cordless mower, a Black and Decker, I forgot about inserting the safety key and scratched my head until I pulled out my owners manual

I never understood the need for a safety key on mowers and snow blowers. The machines already require enough procedures to accidentally prevent startup. The first thing I taught my son since the day he could walk was...never pull and hide that safety key out of the snow blower or Dad will never be able to start it. I'm glad, at least here in the US, that it's a permanent green button you press on the EGO and not an actual safety key.

Does the steel deck 20" mower have the removable safety key? I thought it was permanently installed in the steel deck model. Regardless of that, it's not necessary to depress the safety key and hold the bail in order for the headlight to work, and the self-propel too (if I understand the operation correctly) so it seems there is a bigger problem than just not the normal motor start up sequence. OP's mower seems completely dead since none of the functions work on it.

Bryan, bet it wasn't a product engineering requirement; the legal team asked for it because our society wants to blame others when a mishap happens.

I'm sure some countries have different legal requirements too.

And the 7.5 ah battery works in the other EGO tool (blower)? 
If you got the mower from Home Depot within the last 90 days (1 year if purchased with HD CC) you can easily return/exchange it. If over that return period, you can still try returning it. Home Depot gave me store credit for something I returned that was well past the 90 day limit.
Otherwise, give EGO customer service a call. They will help you out. Call early in the day to avoid hold times. Note that they'll likely be closed on New Year's day.
They can be reached at 1-855-EGO-5656 (1-855-346-5656) from 8:30AM - 8:00PM EST (Monday - Friday) & 10:00AM - 6:00PM EST (Saturday & Sunday).

Yes safety key is inserted and I tried reinserting and following starting procedure of depressing green button first. I may have to return but it no others left at local store so won’t be quick replacement. The 7.5a battery works fine in my ego blower.

Sounds like you've done everything you could. I'd return it unless someone here has a new trick up their sleeve to get the mower fixed.

Definitely a bad mower. The circuitry is shot. I am basing this on the lights not turning on. That's a sure sign of a dud. It's probably the fuse that is not replaceable. If you were in a bind,and couldn't return it, then just remove the plastic panel behind the battery, there is a fuse connected to the red wire coming off of the battery. It's hidden under a small panel once you open the back panel. I am basing this off of the 21" mower as I think they have the same stuff.
