Hydraulic System   
The WB142-5 hydraulic system affords the operator very precise backhoe movements. This system is energy efficient and incorporates two different working modes. In Power mode, both pumps will provide maximum flow and pressure according to demand. In Economy mode, flow and pressure are automatically regulated to provide optimum fuel economy. 
Pump type    Tandem fixed displacement pumps 
Main valves    Closed center, flow sharing valves provide excellent multi-function capability

Service Refill Capacities   
Engine oil  2.4 U.S. gal  9 ltr 
Cooling system  3.7 U.S. gal  14 ltr 
Fuel tank  31.7 U.S. gal  120 ltr 
Hydraulic oil tank  10.8 U.S. gal  41 ltr 
Hydraulic oil system capacity  25.7 U.S. gal  97 ltr 
Front axle oil  1.9 U.S. gal  7 ltr 
Rear axle oil  3.8 U.S. gal  14.5 ltr 
Gearbox oil, Power Shuttle  4.8 U.S. gal  18 ltr 
     
 
Steering   
The front steering wheels are controlled by a hydrostatic load sensing steering priority valve system. 
Minimum turning radius at the outer edge of front tire:     
Without Brakes  13'6"  4100 mm 
With Brakes  11’10”  3600 mm 
 
Transmission   
Shifting between 2WD and 4WD is achieved through an electrohydraulic system. The transmission is operated through a torque converter and a power shift reversing shuttle; the mechanical 4-speed gearbox is synchronized 
Travel Speeds:  mph  km/h 
1st Forward  3.2  5.2 
1st Reverse  3.2  5.2 
2nd Forward  5.3  8.5 
2nd Reverse  5.3  8.5 
3rd Forward  11.5  18.5 
3rd Reverse  11.5  18.5 
4th Forward  23.0  37.0 
4th Reverse  23.0  37.0 
 
Axles   
Heavy duty axles with planetary reduction gears in the wheel hubs. Front axle total oscillation angle is 20°. Differential lock in the rear axle controlled by electro-hydraulic system with a switch on the loader lever. 
Maximum front strength (Dynamic)  16,875 lb  7500 daN 
Maximum front strength (Static)  42,188 lb  18750 daN 
Maximum rear strength (Dynamic)  15,368 lb  6830 daN 
Maximum rear strength (Static)  38,475 lb  17100 daN 
 
Brakes   
Oil immersed disc brakes are actuated by individual braking on each rear wheel with two separate pedals. Total integral braking on the 4 wheels is activated by operating the two pedals at the same time. 
Disc diameter  11.8"  300 mm 
 
Cab   
ROPS/FOPS (Level 2) canopy designed to offer superior visibility. 
 
Loader   
The design of the front loader allows for better tensile strength distribution and parallel movements when raising and lowering the bucket. Due to the linkage geometry, the number of greasing points has been dramatically reduced. 
Standard bucket width  7'2"  2180 mm 
Standard bucket capacity (SAE)  1.00 yd3  0.77 m3 
Standard bucket weight  904 lb  410 kg 
Lifting capacity at maximum height:  6,325 lb  2870 kg 
Lifting capacity at ground level  8,089 lb  3670 kg 
Breakout force  10,116 lb  4590 kg 
 
Backhoe   
The boom has a rounded profile and reinforced structure built with cast ends allowing for 180° rotation while maintaining high rotation torque. 
Bucket breakout force (ISO 6015)  11,351 lb  5150 kg 
Arm breakout force (ISO 6015)  7,670 lb  3550 kg
