DPR22H46STA specifications

The Poulan DPR22H46STA is a robust and versatile riding lawn mower designed for homeowners seeking efficiency and reliability in lawn maintenance. With its 22 horsepower engine and a 46-inch cutting deck, this lawn mower is ideal for tackling medium to large yards, making it a favorite among garden enthusiasts.

One of the primary features of the Poulan DPR22H46STA is its powerful engine. The 22 HP Briggs & Stratton engine provides ample power for cutting through thick grass and uneven terrain. It offers a smooth starting mechanism, ensuring that the mower is ready to go at a moment’s notice. This engine is also designed for efficiency, delivering a balance between power and fuel economy, which is vital for homeowners looking to reduce operational costs.

The 46-inch cutting deck is another standout feature of this model. This size enables the mower to cover a significant area with each pass, reducing overall mowing time. The deck is made from durable materials, ensuring it can withstand the rigors of frequent use while ensuring a clean and precise cut. Additionally, the cutting height can be easily adjusted, giving users the flexibility to customize their mowing experience based on grass length and weather conditions.
