my 21" SP mower which i have had for less than a year starts then shuts off and flashing orange.  I have tried several of my batteries to no avail.  The first day it did this I actually cleaned the deck and got it to work after letting it sit for an extra 45 minutes.  I cut the grass with no issues after I got over the initial problem.  I was able to start and stop it back and forth before i packed it up.    So I am not sure why now all of a sudden it is doing it when it was working fine or rather working when I last packed it up.  I need help, I really like this lawn mower and I would hate having to get rid of it or whatever.   Please HELP!!!

You do know that it has a 5 year warranty. Get it repaired.

Yes i do know it is under warranty.   I'm just hoping i could get it fixed without having to ship it back and such but I guess I will have to if I cannot get a fix.

This is what happens when the clamps aren't fully engaged.

Hmm is there a fix for that. Reason I asked is because I noticed initially it would work when I reset the clamps. However nothing I tried today worker at all. So I was stumped.

If it is the clamps, pulling deliberately up on the handle while closing the clamps usually works.

If the mower runs for a bit before quitting, try pulling the mower backwards.  If it works OK going backwards and quits while being pushed forward, it's almost certainly the clamps failing to hold the handle in its fully extended position.

Ok. I'll try it again tomorrow. I pulled handles all the way up it will start the led turns green for 2 seconds then flashes orange. Even the markers are well above the line and still nothing. Thanks for the suggestions. Is there anything in the hole the is depressed with the clamps pushed in.

Nothing in the holes.  There's a switch that closes when an indentation in the handle extrusion is positioned in front of it.

The clams are easy to remove. Take them off and see if the switch has come lose. The left side while pushing is where It is located.

Gave it a try and it still doesn't work. The switch appears to be fine. I tested it by manually pressing it and out and did what it should. Any other suggestions

The second switch is on the pivot handle. A cam engages a switch to make sure you dont push the mower when the handle is folded forward. This must be the switch failing. Put the handle in a different height position. So when you fold it up, unfold it to a farther setting. Try different ones. This will help.

I do hear a switch click when I move the pivot arm. I've tried starting the mower when I first hear it click after lifting the arm out of the storage position and it still does the same thing. When lifting arm up nothing happens until that first click. Any position after that initial click just yields the same result. Is it possible that grass could some how gotten up in the mower, blocking a sensor or causing the false code to shut down. It's just odd how it acted up then I was able to finish the lawn, use it one time after with no issues and now it won't start up and run once. Lights and self propel work just fine. Just lights up green then immediately flashed orange.

Boo........ I would guess it's an electronics issue. Nothing we can resolve. I'll keep thinking. It's actually overloading. Does the blade spin freely? Are you using an aftermarket blade?

Lol boo indeed. Same blade I bought it with. I even tried new blade and nothing changed. When I turn the blade it spins in both directions with a little resistance. I figure it's normal because I was able to do it with one finger. It even spins up before it starts flashing orange and that's when it stops. Might be electrical like you said. Thanks for all the suggestions. Maybe I can try some compressed air to clear out any debris that may have gotten trapped causing the overload issue. Just throwing ideas out there. Thanks for all the help and I'll keep thinking on possible solutions myself.

Ok so it fails before it gets to full rpm? Like as it ramps up then shuts off and goes orange?

Yes that is what it does. Blade spins up then it flashes orange and the blade stops as soon as its flashing orange.

That means it is failing it's startup sequence

Possibly a wobbly blade but doubt it.

If I was a betting man, I would bet the rpm sensor is bad, which cannot be replaced.

But regardless of what it is at this point, it's in need of repair.

Sorry chike

Thanks for all the feedback and suggestions. I did some more digging around and found that if I take the blade off it starts and runs. The issue is 1 it's not spinning fast enough and 2 it's not keeping a constant rpm. It spins up, then down, then up, then down. Not particular order to its madness but it seems as if it's just registering a load on the motor. Put the blade back on.. Let the flashing begin. So I think Ill just throw in the towel. Really loved this mower though and bragged to everyone about it even have the trimmer, hedger, blower and chainsaw. Was really liking my combo. Now the main member is down.

Buy another one and return it when your repair is done. It's what I would do

I will call them this week. Since I've tried a few things and nothing seems to work. I can hear a chhhh chhhh type sound coming from the motor so I feel it's as though something is prohibiting it from spinning freely. Hopefully they can shed some light. I really love this mower and had to use the string trimmer to do my entire yard. That did not make me a happy camper at all.

The load between having the blade installed and not having it installed will be pretty significant; and even on a properly working mower, the speed sensor should detect that something isn't correct (e.g. the blade is missing), and will trip to a fault condition and power down.  So the only thing that does prove is that the basic electric motor function is working, but tells nothing on whether the speed sensing sub-system is working correctly.
