I bought a B&D 12 amp electric mower that I need a 100 feet of

I already have, for the 100 feet or do I need to get a 100' cord?

Thanks.

I just got a 12 amp mower myself last Sunday, and today I'm going to
get the replacement part that it needs to not vibrate.

I see now problem, if your cords are less than 30 years old, but if
there were a problem especially with something more than 30 years old
it would be that the socket didn't grip the prongs tightly. This can
happen with an indoor extension cord too, because there are lots of
things which use 8 or 12 amps or more. And in my case, by plugging a
heater into a receptacle that was 50 years old, made in 1930.

If you hold the connection in your hand and it's warm at all, it
shouldn't be. Usually it's enough to bend one of the prongs so that
it squeezes on the socket more.

In my case, I was sleeping when the hard rubber plug on the heater
cord got hot enough to flame, an inch or two high. It was morning and
I woke up. I pulled out the plug and it stopped burning for some
reason.

But of course outside, with a normal lawn, you're not going to set
fire to anything and if in a million to one shot, you melt the plug or
socket you can buy another one.
