The Yard-Man E643E is a lightweight yet powerful electric lawn mower. It features a 14-inch cutting deck, making it perfect for small to medium-sized yards. The mower is powered by a potent 12-amp electric motor that provides the efficiency of a gas mower without the noise and emissions. One of the standout features of the E643E is its adjustable cutting height, which ranges from 1 inch to 3 inches, allowing users to customize the grass height according to their preferences and seasonal needs. This model is equipped with a rear bagger that collects clippings for easy disposal, ensuring a clean and manicured appearance for your lawn.

On the other hand, the Yard-Man E663H is a self-propelled gas mower built for those who require a more robust solution for larger lawns.
