Which is an advantage of the two lever system in TLB operation?

The two lever system in Tractor-Loader-Backhoe (TLB) operation provides the advantage of less operator fatigue. This system is designed to streamline operations by allowing the operator to control multiple functions with reduced physical effort. By using two levers, operators can efficiently manage the movements of the loader and backhoe with minimal strain, as it requires less hand and arm movement compared to more complex control configurations that utilize multiple levers or pedals. The ergonomic design of the two lever setup enhances comfort and minimizes the potential for fatigue over extended periods of operation, which is especially valuable in demanding work environments. This ultimately leads to improved operator efficiency and productivity.
