A loader is not the most efficient machine for digging as it cannot dig very deep below the level of its wheels, like a backhoe can. Their deep bucket can usually store about 36 cubic meters of earth. The front loader39。7. Bucket Controls：The use of a PPC hydraulic control valve offers lighter operating effort for the work equipment control levers. The reduction in the lever force and travel makes it easy to operate in the work envy ornament.Control positions：Boom：Raise, hold, lower, and float；Bucket ：Roll back, hold, and dump8. Hydraulic System：Capacity (discharge flow) enginerated rpm：Loader pump；Steering pump；Pilot pump(Geartype pumps)；Relief valve setting；Control valve：2spool open center type；Hydraulic cylinders：Doubleacting, piston；Hydraulic cycle time (rated load in bucket)：Raise，Dump，Lower (empty)，Total cycle time1. The roundback bucket design is stronger with no angled corners. This configuration makes it easier to fill and dump — improving productivity.2. The ROPS/FOPS structure protects and shields the operator.4. A safety system locks lift, tilt and drive systems when the operator leaves the seat, raises the seat bar, or turns off the ignition switch. The brakes are wettype multiple discs that require no maintenance.6. The rugged allwelded unitized frame is constructed of .375inch gauge steel for years of productivity. Step bushings are placed in all key pivot areas to increase strengt
