What It Does:

Serves as the stick (arm) hydraulic actuator mounted between the main boom and the bucket linkage on Caterpillar E and F series backhoe loaders. Powered by high-pressure hydraulic fluid, it extends and retracts the stick to control reach, trench digging depth, and material crowding functions.

Importance:

Essential for achieving precise digging reach, optimal excavation depth, and maximum stick crowding force during trenching and earthmoving operations. Built with a robust 40 kg heavy-walled barrel and high-strength forged rod, it effectively absorbs dynamic shock loads and severe bending stress, while advanced internal seals prevent fluid bypass under continuous heavy operation.
