To the 20066, it adds an electric start option which starts the mower at the turn of a key. Like all models in the series, the 20067 utilizes a 22" steel deck designed to handle rough and uneven terrain. The height of cut can be set at one of nine positions between 1.25" and 4.25". It lacks only a blade override system available with the top-of-the-line model. Two years of full warranty coverage are offered.
