Yes, Honda made three 17" mowers. The HR173 had a gas engine mounted on the plastic deck. The HR17E had and electric motor on the same plastic deck as the HR173 and the HR17 had the same gas engine as the HR173 mounted on an aluminum deck.
I used to have a Toro snowblower with a Briggs motor in it. It actually ended up burning out. I was really disappointed.That's kind of goofy! Most people don't realize that Briggs makes a lot of electric motors. The engineering club at my school has an electric car with a Briggs electric motor.
Like the one on my electric Didier 20 wood splitter...Most people don't realize that Briggs makes a lot of electric motors.
