With which buckets is the hydraulic thumb clamp configured to work?

The correct answer is that the hydraulic thumb clamp is configured to work with the rock bucket and ditch cleaning bucket. The hydraulic thumb is designed to enhance the versatility of the excavator's operation, allowing for gripping and holding materials in conjunction with specific types of buckets.

When using a rock bucket, the hydraulic thumb is particularly effective as this type of bucket is designed for heavy-duty operation, often handling large and uneven materials such as rocks. The thumb can grasp these materials securely, making it easier to load them onto trucks or move them to different locations.

Similarly, the ditch cleaning bucket is typically wider and more suited for removing material from ditches or trenches, where gripping is essential. The combination of the thumb with a ditch cleaning bucket allows an operator to efficiently clear debris, ensuring that the material can be manipulated with greater control.

In both cases, the thumb works in tandem with these bucket designs to enhance efficiency and precision during excavation and material handling tasks, making them ideal pairings with the hydraulic clamp system. Other combinations may not provide the same degree of functionality or operational efficiency as these two specific bucket types do when paired with a hydraulic thumb.
