US gal STEERING WB-N/WBPS-N/WB-N/WBPS-N The front wheels are controlled by a hydrostatic load sensing steering priority valve system Turning radius at outer edge of front tire: Without Brakes mm '" With Brakes mm '" The new Komatsu steering system ensures excellent maneuverability and versatility and allows the operator to choose from the following three different steering modes by the push of a button: Two Wheel Steering, Four Wheel Coordinated Steering, Crab Steering Turning radius ( wheel coordinated steering mode, w/o individual braking): Edge of tire mm '" Edge of bucket mm '" AXLES HYDRAULIC SYSTEM The Hydraumind hydraulic system affords the operator very precise backhoe movements. This system is energy efficient and incorporates two different working modes: economy and constant power. The advanced hydraulic system includes the speed up function to increase the working speed of the front loader. System HydrauMind Type Closed center Load Sensing System (CLSS) with economy/power selector switch (power mode is the default setting) Pump type Variable displacement axial piston Pump control system Load Sensing set to adjust the hydraulic power Main Valve Load Independent Flow Divider LIFD modular type Max delivery ltr/min. gal/min Work pressure WB-N/WBPS-N bar, psi WB-N/WBPS-N/ bar, psi WB-N/WBPS-N/WB-N/WBPS-N Heavy duty axles with planetary reduction gears in the wheel hubs.

2 BAC K H O E L OA D E R S WB/ TRANSMISSION WB-N/WB-N Switching between WD and WD is achieved through an electro-hydraulic system. The transmission is operated through a torque converter and a power shift reversing shuttle; the mechanical -speed gearbox is synchronized. Travel Speeds st nd rd th km/h mph km/h mph km/h mph km/h mph Forward Reverse WBPS-N/WBPS-N/ Electronically-controlled, four-wheel-drive, full powershift transmission. Twist Grip or EGM TM (Electronic Gear Management) gear Controls for changing driving direction and gears at full power without disengaging the drive. Twist Grip Controls in manual mode on WBPS-N/WBPS-N EGM TM Gear Controls in automatic or manual mode on Travel Speeds st nd rd th km/h mph km/h mph km/h mph km/h mph Forward Reverse LOADER The design of the front loader allows for better tensile strength distribution and parallel movements when lifting and lowering the bucket. Due to the linkage geometry, the greasing points have been dramatically reduced.
