Which of the following is not a typical tool used in manual ROW maintenance?

In manual Right-of-Way (ROW) maintenance, tools are specifically chosen for their ability to manage vegetation effectively while also ensuring safety and efficiency. The chainsaw, handsaw, and hedge trimmer are all manual tools that require physical handling and are used for cutting back or trimming trees and shrubs in the ROW.

The chainsaw is a powerful tool suitable for larger limbs and trees that need to be cut back or removed. A handsaw is more manual and is often used for smaller branches or delicate operations where precision is needed. The hedge trimmer, often manual or electric, is designed for shaping and trimming shrubs or hedges.

In contrast, a chemical sprayer is not typically categorized with manual tools. While it is a vital component of vegetation management, it does not require the same type of manual labor as the other tools listed. Instead, a chemical sprayer is used for applying herbicides or pesticides, which involves the use of chemicals to control unwanted plant growth rather than physical removal or trimming of vegetation. This makes it distinct from the hands-on nature of the other tools in the context of manual ROW maintenance.
