Power Control

Valtra’s unique Power Control system selects the best engagement of the forward-reverse shuttle, four-wheel-drive, HiShift button-controlled clutch, Powershift gears and PTO every time whatever the situation.

  
     

 		  

Driving directions can be switched using the shuttle lever without having to use the clutch. The transition is always smooth and fast, regardless of the load. The shuttle lever also controls the handbrake.

The HiShift button-controlled clutch allows the driver to change gears or ranges without using the floor clutch. The floor clutch can still be used when extra precision is needed.
 



 

  

The benefits of the Powershift transmission are realised best in work that requires a lot of shifting. The Powershift transmission can be operated either by push buttons or by using one of two automatic programmes. The Auto 1 and Auto 2 programmes change gear automatically when engine speed goes above or falls below the preset rpm.

Auto 1
In Auto 1 the Power Control system selects the optimal gear whever the engine speed goes above or falls below a certain rpm. Auto 1 is preset at the factory. Auto 1 is ideal for field work, PTO work and transporting loads.

Auto 2
In Auto 2 the driver can preset the engine speeds for shifting gears according to the type of work. The Power Control system automatically takes care of shifting the gears. Auto 2 helps maximise the efficiency of using tractor- implement combinations.

Kick down function
Both Auto 1 and Auto 2 feature a kick-down function that speeds up shifting. When the accelerator pedal is pressed down fast, the system will temporarily shift down to a lower gear (when the system allows). The kick-down function also works when braking.
 
  AutoTraction
Autotraction automatically disengages the drive when the driver presses the brakes at less than 10 km/h or when the engine speeds drops below 1000 rpm. When the engine speed increases above 1000 rpm or the brake pedal is released, the drive engages smoothly. AutoTraction is ideal for stop-start operations.
 




 		   Automatic four-wheel-drive
Valtra’s 4WD system prevents wheel spin and soil damage. The system automatically engages four-wheel-drive temporarily when moving off from rest, changing gears, using HiShift or changing directions. The driver can select for how long the four-wheel-drive is activated. The system may also be deactivated if required. The four-wheel-drive system and differential lock can be controlled either automatically or manually.
