Standard Hardware Sizing

When a washer or nut is identified as 1/2”, this is the Nominal size, meaning the inside diameter is 1/2 inch; if a second number is present it represent the threads per inch

When bolt or capscrew is identified as 1/2 - 16 x 2”, this means the Nominal size, or body diameter is 1/2 inch; the second number represents the threads per inch (16 in this example, and the final number is the body length of the bolt or screw (in this example 2 inches long).

The guides and ruler furnished below are designed to help you select the appropriate hardware and tools.

3547 specifications

The Snapper 3547 is a highly versatile and efficient riding lawn mower designed for both residential and commercial use. This machine is engineered for performance, offering a blend of power, maneuverability, and convenience that makes lawn care a breeze.

One of the standout features of the Snapper 3547 is its powerful engine. Equipped with a robust 19.5 HP Briggs & Stratton™ engine, this mower ensures reliable starting and exceptional cutting power. The engine is paired with a durable transmission system that provides smooth operation and allows users to easily navigate their lawns. This combination of power and transmission efficiency means that users can tackle a variety of grass types and terrains with confidence.

The Snapper 3547 also boasts a cutting deck that measures 47 inches. This wide cutting deck enables the mower to cover a larger area in less time, significantly reducing mowing sessions. The deck is made of high-grade steel, ensuring longevity and resilience against wear and tear. Additionally, users can adjust the cutting height with ease, thanks to its six-position height adjustment feature, enabling them to achieve the desired grass length for a healthier lawn.

Maneuverability is another key characteristic of the Snapper 3547. With a tight turning radius and responsive steering, the mower is exceptionally easy to handle, even in intricately landscaped areas. The design incorporates a comfortable, ergonomic seat that provides excellent support during prolonged use, making it ideal for larger properties.

Moreover, the Snapper 3547 is equipped with advanced technologies that enhance its overall functionality. The Hydrostatic transmission allows for seamless speed and direction changes without the need for clutches or gear-shifting, giving users a smoother and more enjoyable mowing experience. Additionally, the mower is compatible with various attachments, enabling users to switch from mowing to leaf bagging or tilling, making it a true multi-tasking tool.

Safety features are also a priority in the design of the Snapper 3547. An automatic safety kill switch is a crucial element; it ensures the mower stops when the operator leaves the seat, minimizing the risk of accidents.

In summary, the Snapper 3547 is a reliable and powerful riding mower that combines performance, comfort, and safety. Its strong engine, wide cutting deck, maneuverability, and advanced technologies make it an excellent choice for anyone looking to maintain their lawn efficiently and effectively.
