Which activity is included in the maintenance of arena equipment?

The maintenance of arena equipment is essential to ensure that all systems are functioning correctly and are safe for use. Checking the arena drag for loose bolts is a critical task that directly relates to the upkeep and operational efficiency of the equipment. The arena drag is used for maintaining the footing and surface of the arena, which is crucial for both the safety of the horses and riders and the quality of the riding experience. Loose bolts can lead to malfunctions or breakdowns, resulting in equipment failure or safety risks during use. Regular inspections such as this help prevent larger problems down the line.

The other activities listed, while involving care and management within an equestrian context, do not fall under the specific maintenance category of arena equipment. Fertilizing the ground pertains to agricultural practices, inspecting horses for fitness relates to animal health and readiness for work, and conducting riding lessons focuses on education and training for riders. These tasks are important in their own right but are not directly associated with the maintenance of arena-specific equipment like the drag.
