[. . . ] Easy for heavy digging. Bucket capacities Switch pump 13. 0m3 17cu. yd While the lift boom is raised, all the hydraulic flow from the switch pump goes to the work equipment. Fast Normal loading mode: All hydraulic flow is transferred directly to the work equipment. Digging/Loading Loader pump Active Working Switch Normal Loading Large Dumping Clearance The WA900-3 was designed with ample dumping clearance for dump truck matching. 2450mm 4640mm 4285mm WA900 & HD785 Excellent Stability The WA900-3 has the widest tread in its class 3, 350mm (11') and a long 5, 450mm (17'11'') wheelbase, for maximum machine stability. Switch pump Static tipping load (with 45/65-45-58 PR (L-5) tires / bucket 13. 0 m3 17. 0 yd3) Fast W=5210mm The hydraulic flow from switch pump goes to work equipment. Traction while digging/shoveling is not increased. The speed of the lift boom is increased in all operations. 65670 kg 144, 780 lb 40° full turn: 57430 kg 126, 610 lb Straight: High Breakout Force Komatsu wheel loaders have high-tensile steel Z-bar loader linkages for maximum rigidity and maximum breakout force. [. . . ] This results in increased rim pull for better bucket penetration and reduced cycle times for higher productivity. Hold switch: Auto shift is selected and if the operator turns on this switch when the lever is at the 3rd gear speed position, the transmission is fixed to that gear speed. Kick-down switch 1st 2nd 1st hold 2nd 3rd Comfortable Operation Steering Wheel Type Remote Boom Positioner The highest and lowest position of the bucket can be set from the cab to match any truck body.
