I bought a B&D 12 amp electric mower that I need a 100 feet of
extension cord for. Would it be advisable to combine two cords, which
I already have, for the 100 feet or do I need to get a 100' cord?

Depending on the flexibility of the cord, the loop can pull tighter
with tension and create fairly sharp bends at the plugs, which is bad
for the cord. I make an extra turn when I'm doing that so the
friction between the cords is what takes the strain. If it's a
heavier gauge cord, it's less of a problem.
The only downside I've run into when joining cords like that for use
with a moving tool (mower) is that the "lump" in the middle of the cords
tends to hang up on things far more often than a full length cord will.
I got a new B&D hedge trimmer last year and I like the fact that there's
no cord at all on it, just two plug prongs sticking out below the handle
and a built in lug to keep the extension cord in place so that a pull on
that cord won't disconnect the plug.
Don't know how things are at your house, but at mine, it's a hard and fast
rule that if there is ANYTHING for a cord to hang up on, that cord will seek
it out, and not come unhung no matter how many times you flip the cord. You
must physically walk all the way back and free it from this 1/2" protrusion
or tiny tiny stub of a root.
What's the big deal? If they didn't want you to daisy chain extension
cords, they would hard wire a long tail to a tool.
And multi strip plugs. Each one will plug in six more strips. The number
of final outlets is infinite.
Or so some people think...............................
It'd take an infinite amount of time to collect infinite power strips,
and you'd need infinite space to put them in.
Then, some outlets would be infinitely far from the power source,
connected by an infinite length of wire, in infinitely many pieces
with infinitely many connectors. Expect an infinite voltage drop.
Now consider that infinity doesn't exist in the real world...
I can see you haven't met my wife. I've found birdsnest configurations of
extension cords and MOS's (some extension cords going to another MOS) and I
just cringe. Her attitude is, "Oh, look, there's two empty plugs, and I
need to plug in a crock pot and an iron."
Starting with a duplex receptacle, the formula is:
O = S (N - 1) + 2
O = total number of outlets
S = number of power strips
N = number of outlets per power strip
Where N is always 6, here's some values of O (for a given S):
But you wanted:
O = infinity * (6 - 1) + 2
BTW, this is true even for those too stupid to figure out where the
"-1" came from.

There's a better way. You need:
1. short extension cord (suitable for mower)
2. power strip (with 4-8 outlets)
3. duct tape
Use #3 to attach #2 to the mower handle.
Plug #2 into #2.
Use #1 to connect the mower to #2.
Everything's plugged in so it must work :-)
If it doesn't work, trace the problem and see if you can explain why
it's not working. If you really understand that, it'll be of great
benefit to you in the future.
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
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.
