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) 
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  43.6 gal/min  165 ltr/min 
Work pressure  3,553 psi  245 bar 
 
Service Refill Capacities   
Engine oil  2.4 U.S. gal  9 ltr 
Cooling system  3.7 U.S. gal  14 ltr 
Fuel tank  39.6 U.S. gal  150 ltr 
Hydraulic oil tank  10.8 U.S. gal  41 ltr 
Hydraulic oil system capacity  25.6 U.S. gal  97 ltr 
Front axle oil  2.0 U.S. gal  7.5 ltr 
Rear axle oil  3.8 U.S. gal  14.5 ltr 
Gearbox oil, Power Shuttle  5.3 U.S. gal  20.2 ltr 
Gearbox oil, Power Shift  7.4 U.S. gal  28.0 ltr 
 
Steering   
The front steering wheels are controlled by a hydrostatic load sensing steering priority valve system. 
Turning radius at outer edge of front tire  13'1''  4000 mm 
Turning radius (using brakes) at outer edge of front tire  11'2''  3400 mm 
 
Transmission   
Electronically-controlled, four-wheel drive, full powershift transmission. Twist Grip or Electronic Gear Management (EGMTM) gear controls for changing driving direction and gears at full power without disengaging the drive. Twist Grip Controls in manual mode. 
Travel Speeds  Forward  Reverse 
1st  4.0 mph / 6.5 km/h  4.0 mph / 6.5 km/h 
2nd  7.5 mph / 12.0 km/h  7.5 mph / 12.0 km/h 
3rd  14.3 mph / 23.0 km/h  14.3 mph / 23.0 km/h 
4th  24.9 mph / 40.0 km/h   
 
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 loader lever. 
Maximum front strength (Dynamic)  22,031 lb  9800 daN 
Maximum front strength (Static)  53,392 lb  23750 daN 
Maximum rear strength (Dynamic)  16,861 lb  7500 daN 
Maximum rear strength (static)  42,152 lb  18750 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 and FOPS level 2. Cab designed to offer the best visibility, ergonomics, low noise, and operator comfort. Two doors, full opening rear window with front and rear windshield wipers. Interior features include a fully adjustable seat, fresh filtered air intake ventilation, and easy to reach front and side dash boards. 
 
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  7'9''  2356 mm 
Standard bucket capacity (SAE)  1.25 yd³  0.95 m³ 
Standard bucket weigh  1,000 lb  454 kg 
Lifting capacity at maximum height  8,598 lb  3900 kg 
Lifting capacity at ground leve  11,020 lb  5000 kg 
Breakout force  13,224 lb  6000 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)  13,505 lb  6126 kg 
Arm breakout force (ISO 6015)  8,631 lb  3915 kg
