917.27066 specifications

The Craftsman 917.27066 is a powerful and reliable riding lawn mower designed to make lawn maintenance a hassle-free task. This model combines a strong build quality with modern technology, catering to homeowners who value efficiency and performance in yard care.

One of the standout features of the Craftsman 917.27066 is its robust engine. Equipped with a 19 horsepower Briggs & Stratton engine, it delivers ample power that allows it to tackle various terrains with ease. This engine is designed for durability and efficiency, ensuring that users can cover more ground without frequent refueling.

The mower includes a 42-inch cutting deck, which provides a well-balanced cutting width perfect for medium-sized lawns. The size of the deck facilitates a clean and precise cut, ensuring that users can achieve a professional-looking finish in minimal time. The adjustable cutting height feature, with multiple settings, allows users to customize the grass length to meet their specific lawn care needs.

In terms of technology, the Craftsman 917.27066 features an electric start for convenient operation. This means no more pulling on a starter cord repeatedly; simply turn the key, and you're ready to mow. The adjustable seat adds to the comfort, making it suitable for extended use during those long mowing sessions.

The ergonomically designed steering wheel and intuitive control layout enhance the user experience by making the mower easy to maneuver. The tight turning radius enables users to navigate around flowerbeds, trees, and other obstacles, ensuring a thorough cut without leaving unkempt patches.

Another notable characteristic is the transmission system. The Craftsman 917.27066 features a hydrostatic drive system, which provides seamless speed adjustments and enhances overall ease of use. This is particularly beneficial for beginners who may find traditional gear transmissions challenging.

Moreover, the mower is designed with durability in mind. Its reinforced frame and heavy-duty materials ensure it can withstand the wear and tear of regular use. The incorporation of safety features, such as a safety switch that stops the engine when the operator leaves the seat, adds an extra layer of protection for users.

Overall, the Craftsman 917.27066 is a versatile and powerful riding lawn mower that combines ease of use, comfort, and efficiency, making it an excellent choice for homeowners who want to maintain their lawns effortlessly. Whether tackling flat surfaces or uneven terrain, this mower provides a dependable solution for all your lawn care needs.
