I just purchased my first lawn mower.
It is a Black & Decker Lawn Hog 12 Amp 18" Electric Mulching Mower model
MM575.
The table for selecting an extension cord is confusing.
The model is recommended for lawns up to 100'.

The cords listed for 12-16 Amps are 120V SJTW 14/3 for 25 feet and 12/3 for
50 feet. No recommendations at all for over 50 feet.
You can see my confusion since it is supposed to be recommended for 100'
lawns.

I need 75' to reach my fence line and parkway.
Should I go with a SJTW 12/3 gauge 50 foot cord and add a 25 foot cord when
mowing the perimeters?
Or should I get a SJTW 10/3 cord (not even mentioned at all in the table)?
