Transmission

All A Series models come with a fully synchronised 12+12 transmission with a straightforward design and excellent efficiency. The standard electronic front linkage and versatile automated transmission facilitate tasks. The new and improved A Series allows customers to enjoy a level of productivity and technology that was previously available only on larger tractors.

Best forward-reverse shuttle on the market

The new A Series HiTech models feature Valtra’s electronic HiTech forward-reverse shuttle, which is widely considered the best on the market.

The smooth and precise shuttle improves productivity and comfort, especially when performing front-loader tasks.

The system also features an integrated handbrake, a luxury even on bigger tractors. The handbrake is engaged automatically when the shuttle switch is in P mode or when the engine is turned off. Selecting a driving direction releases the handbrake, so it cannot be left on by mistake. The system is therefore extremely easy and safe.

Alongside the HiTech models, Classic models are offered with the traditional synchronised forward-reverse shuttle.

HiTech models naturally include an electrohydraulic dual-speed PTO. The multidisc clutch is controlled effortlessly by the suspended clutch pedal, while the hydraulics ensure a soft release. PTO controls are optionally available in the rear mudguards. The PTO shaft can also be replaced if necessary (6/21 splines).


Valtra HiShift button-operated clutch control

Valtra’s HiShift feature operates the drive clutch when changing gears mechanically. HiShift saves you from having to press the clutch pedal is most practical driving situations.

You only have to use the clutch pedal when starting the engine for safety reasons. If you want to make individual choices according to your driving style, you can of course still use the clutch pedal. Actively using the HiShift feature makes work more efficient and reduces the strain on your clutch leg and foot.

The drive clutch is computer operated. Each driving direction has its own service-free multidisc clutch.

Valtra HiTech means practical automation

The automated forward-reverse shuttle and electronic engine management facilitate everyday tasks.

For example, the optional cruise control simplifies driving on roads and working in fields, as the required driving speed or engine speed can be easily stored and recalled.

Valtra’s excellent Autotraction feature is standard on A Series HiTech models. When Autotraction is activated, the tractor can be stopped from normal working speeds (below 12 km/h) simply by applying the brakes or lifting your foot from the gas pedal. The tractor then starts again when you release the brake or increase the revs. An electronic drive clutch developed by Valtra ensures smooth yet rapid starts.

The 4WD can be programmed to activate when changing directions and starting, or only when the linkage is in the working position. The optional automation package also controls the PTO.
