MM875 electric lawnmower

there is a wire connected to the carby at the end of the throttle cable
that wire makes contact with the throttle plate when the engine stop is required
if that wire has fallen of or burnt through or touching the plate it will stop the engine and there will be no spark

1) Something is shorting before completing the circuit. Look for any bear wires that may be touching the metal of machine, nicks or burnt spots on wires. 2) Overload on ampherage. For more information you might try visiting the Lawnmower World Forum. They have a lot of helpful ideas and more experienced people.

that was burnt carbon coming out and you did overwork that lawn mower not dangerouse but keep mowing long grass you will end up buy anew one soon

Nope. If the grass is too high, knock it down to size with a weedeater first. These electric mowers cannot handle the tall, high stuff. If you do, you will surely burn it up.

Good morning,

This site has an abundance of info, from tech specs, FAQs, and TSBs:

Here's the scoop on the MM875: it has a plastic piece called a "blade insulator" (part # 241381-01) that "locks" the shaft to the blade, so that you can remove the nut by stopping or blocking the blade. If it has been damaged or stripped out, then stopping the blade won't do anything. However, the metal spacer directly under the nut IS still locked to the shaft (because of its shape), so you can use a pipe wrench or something to hold that in place and unscrew the nut. You might even be able to get someone in a home improvement store to do this for you. But you will still need to replace the insulator, which is only a few dollars.

You were NO help at all. I asked for a location to have an electric lawnmower repaired in my area. You gave me a source 2500 miles away. Obviously I cannot count on assistance through this site. What happened to REAL PEOPLE who can offer some intelligent reply? If I could repair a lawnmower, why would I need to ask you?

Does it crank over at all? I would look at all the fuses, and check the wiring going from the battery to the starter. Also check the key switch for corrosion.
