The John Deere 400 series manufactured between 1975 and 1983. And in that time, 400, 420, and 430, which are the first, second, and third brands in the 400 series, were produced.

The 400 series is powerful enough to serve both home and commercial operators and equipped with engines of 20 to 22 Horse powers. Their powerful engines, durability, and cutter width of 48 to 60 inches make them ideal for cutting 3 to 5 acres of grass.
