Which of the following is a common type of TLB attachment?

The correct choice is the auger, which is a common attachment for a tractor-loader-backhoe (TLB). Augers are used to drill holes in the ground for various applications, such as setting fence posts, planting trees, or installing foundations. This attachment enhances the versatility of the TLB, allowing operators to perform tasks that require precise hole placements with various diameters depending on the specific auger size used.

While other attachments like forklifts and cranes are extremely useful in heavy equipment operations, they are typically associated with different types of machinery rather than TLBs. A forklift is predominantly used for lifting and transporting materials, while a crane is intended for hoisting heavy loads vertically and horizontally, requiring different operational dynamics compared to a TLB. The trencher is also recognized as a TLB attachment, but it is less common than the auger, which is frequently utilized in both commercial and residential projects for efficient digging and drilling tasks.
