917.272068 specifications

The Craftsman 917.272068 is a highly efficient and robust lawn tractor designed to meet the needs of both homeowners and professional landscapers. Built with durability and performance in mind, this machine is ideal for tackling a variety of mowing tasks, whether you have a small residential lawn or a more expansive grass area.

One of the standout features of the Craftsman 917.272068 is its powerful 24 HP engine, which provides ample power to handle tough mowing conditions. The engine is specifically designed for reliability and longevity, ensuring that it can provide consistent performance over many seasons. Coupled with the dual blade system, the mower provides an even and clean cut, reducing the need for double mowing and optimizing efficiency.

The 917.272068 is equipped with a 42-inch cutting deck, allowing for wide swath mowing while maintaining agility around obstacles. The cutting height is adjustable, providing users with the flexibility to choose from various settings, ensuring a tailored cut to suit the season or grass type. This versatility makes it particularly advantageous for users with varying mowing preferences and lawn conditions.

Another notable feature is the hydrostatic transmission, which allows for smooth and effortless control of speed and direction. This feature enhances ease of use, particularly for those who may not be accustomed to operating larger machinery. The responsive controls enable precise maneuverability, making it possible to navigate tightly spaced areas with ease.

The Craftsman 917.272068 also includes comfortable seating and a user-friendly dashboard that displays essential information at a glance, such as fuel level and maintenance reminders. This focus on operator comfort is a crucial aspect of its design, making long mowing sessions more enjoyable and less fatiguing.

In terms of technology, the Craftsman 917.272068 supports mulching and rear discharge capabilities, providing users with the option to either recycle grass clippings back onto the lawn for nutrient replenishment or easily discharge clippings behind the mower. This dual functionality enhances the utility of the mower, catering to different user preferences and lawn care practices.

Overall, the Craftsman 917.272068 stands out with its fusion of power, efficiency, and user-friendly features. Its reliable performance, combined with adjustable mowing options and comfortable operation, positions it as a top choice for anyone looking to achieve a well-maintained lawn.
