917.289071, 917.289070, 917.28907, 917.289072 specifications

The Craftsman 917.28907, 917.289071, 917.289070, and 917.289072 represent a series of high-performance lawn mowers designed to tackle various yard maintenance tasks with efficiency and ease. Each model in this lineup features a powerful engine combined with user-friendly technologies, making them ideal for homeowners seeking reliability and robust performance in their lawn care equipment.

One of the standout features of these mowers is their cutting deck design. With a wide 42-inch deck, the Craftsman series enables users to cover more ground in less time, ensuring a neat and professionally looking lawn. The deck is constructed from durable materials, designed to withstand regular use while maintaining sharpness for effective cutting.

The mowers are powered by dependable gasoline engines that provide consistent performance and are built to handle various terrains. The powerful engines ensure that even tougher jobs, such as mowing overgrown grass, are completed without difficulty. Furthermore, these models are equipped with electric start capabilities, allowing for easy starting with the turn of a key, eliminating the hassle of traditional pull-start systems.

Another noteworthy technology found within these models is the adjustable cutting height feature, which allows users to customize the mow height according to their lawn type and seasonal needs. This versatility is crucial for maintaining a healthy lawn and achieving the desired aesthetic appeal.

Ergonomically designed, these mowers prioritize user comfort and ease of handling. Features such as padded handles contribute to a more comfortable grip while mowing, reducing strain during extended use. Additionally, the models are designed with maneuverability in mind, making them easy to navigate around obstacles like trees, flower beds, and other landscaping features.

The Craftsman 917.28907 series models also emphasize maintenance convenience. They come equipped with a rear discharge, which effectively disperses grass clippings behind the mower, resulting in a neat finish without the need for additional cleanup. The side-mounted bagging system further enhances lawn care, allowing for efficient grass collection.

In summary, the Craftsman 917.28907, 917.289071, 917.289070, and 917.289072 lawn mowers are engineered for durability, ease of use, and efficiency. With powerful engines, versatile cutting options, and user-centric design features, these mowers stand out as exemplary solutions for homeowners looking to maintain beautiful and healthy lawns with minimal effort.
