You can replace the backhoe bucket with a breaker for breaking smashing concrete and rock. There are loader buckets with a retractable bottom which help empty the load more quickly. Retractable bottom loader buckets are often used for grading and scratching off sand as well. The front assembly on a backhoe may be either removable or permanently attached. Operationally, loaders are built to be multifunctional. They are nifty in construction, light transportation, excavation, breaking asphalt, and even paving roads.
