1. The Sheep: The most obvious answer is the sheep themselves. They are the main source of income for the station and require a lot of care and management.
2. The Dogs: Working dogs are crucial for herding and managing the sheep flock. They are often referred to as "workhorses" because of their tireless efforts and vital role in keeping the sheep organized and safe.
3. The Station Vehicles: Four-wheel drive vehicles are essential for traversing the often rugged terrain of a sheep station. They are used for mustering, checking fences, and transporting supplies. These vehicles are often considered "workhorses" for their reliability and durability.
4. The Human Workers: The station staff are the backbone of the operation. They put in long hours and hard work to manage the sheep, maintain the property, and ensure the smooth running of the station. They are often referred to as "workhorses" for their dedication and commitment.
Ultimately, the best answer depends on the specific context of the question. However, all of these options are vital components of a sheep station and could be considered "workhorses" in their own right.
