MTD1640NAVCC, MTD1840AVCC specifications

The Yard Machines MTD1840AVCC and MTD1640NAVCC are powerful lawn mowers designed for efficient grass cutting and yard maintenance, perfect for homeowners seeking reliability and performance. These models stand out for their robust construction, user-friendly features, and advanced technologies that ensure a seamless mowing experience.

The MTD1840AVCC model is equipped with an 18-inch cutting deck, making it ideal for small to medium-sized lawns. It features a reliable 40V lithium-ion battery, which not only provides impressive runtime but also operates quietly, reducing noise pollution during use. The mower offers three cutting options: mulching, side discharge, and rear bagging, allowing users to choose the best method for their yard care. The adjustable cutting height accommodates different grass lengths, making it versatile for various gardening needs.

In contrast, the MTD1640NAVCC model comes with a slightly smaller 16-inch cutting deck, making it an excellent choice for tighter spaces and small yards. It shares many of the same benefits as the MTD1840AVCC, with a 40V lithium-ion battery for efficient performance. The MTD1640NAVCC also offers multiple cutting modes, providing flexibility in achieving the desired finish for your lawn.

Both models are built with lightweight materials, ensuring easy maneuverability even on uneven terrain. The ergonomic handle design adds comfort during use, reducing strain on the arms and back. Additionally, the foldable handle feature allows for compact storage, making them ideal for garages and sheds with limited space.

Safety features have not been overlooked, with both mowers equipped with a blade brake mechanism that stops the blade quickly when the user releases the handle. This ensures added safety, especially in households with children or pets.

In conclusion, the Yard Machines MTD1840AVCC and MTD1640NAVCC are exemplary lawn mowers that combine innovative technology with practical features. Their durable construction, efficient battery operation, and versatile cutting options make them superb choices for maintaining a beautiful lawn. Whether you have a small urban yard or a larger suburban garden, these mowers deliver performance and reliability you can trust.
