780r specifications

The Ryobi 780R is a powerful and reliable gas-powered string trimmer known for its exceptional performance and user-friendly features. Designed for both professionals and homeowners, this tool offers versatility and efficiency for tackling tough trimming jobs around the yard.

One of the standout features of the Ryobi 780R is its robust 30cc 2-cycle engine. This engine provides ample power to handle thick weeds and overgrown grass, ensuring a clean and precise cut with every pass. The lightweight design of the trimmer enhances maneuverability, making it easy to navigate around obstacles such as trees, flower beds, and garden furniture.

The trimmer is equipped with a premium 18-inch cutting swath, allowing for a wider range to be covered in a single pass. This feature can significantly reduce the time required to complete larger trimming tasks. Additionally, the variable speed throttle gives users the flexibility to adjust the cutting power based on the density of the vegetation, offering greater control.
