Which of the following is a common tool used in landscape maintenance?

A shovel is a fundamental tool in landscape maintenance due to its versatility and effectiveness in a variety of tasks. It is primarily used for digging, planting, and moving soil or mulch, making it indispensable for planting beds, gardens, and other landscapes. Its design allows for efficient lifting and transferring of materials, which is crucial for maintaining the landscape's aesthetic and health.

In contrast, while a paint sprayer is useful for painting, it does not directly contribute to typical landscape maintenance tasks. A text editor is not a physical tool used in landscape work; rather, it is a software application for text editing. A hammer, though valuable in construction and certain landscaping applications, does not serve the frequency of roles that a shovel does in day-to-day landscape maintenance activities. Therefore, the shovel stands out as the most practical and commonly utilized tool in this context.
