Valtra's small and agile new 75-130hp A Series tractors have the potential to be popular sellers with dairy and drystock farmers here.

The previous generation of the A Series offered two models producing between 88 and 103 horsepower, while three smaller A Series models were available with 50 to 78 horsepower.

This new fourth generation now comprises a total of seven models.

All models are powered by AGCO Power Stage 4 engines.

The three smallest models have three-cylinder 3.3-litre engines, while the four larger models have four-cylinder 4.4-litre engines.

Exhaust emissions are controlled with efficient and space-saving SCR (Selective Catalytic Reduction) technology with only the smallest, A74 model, fitted with a cooled EGR system.

Combined with totally new, high-pressure common rail injection systems, the new engines produce high power economically.

The A4 Series features a brand new modular chassis design that enables a broad model line-up to be manufactured efficiently and without compromising any features.


WHEELBASE

For example, the three smallest models have a wheelbase of 2250 millmetres, the next larger model has a wheelbase of 2430 millimetres while the two largest models have a wheelbase of 2500 millimetres. Similarly, the smaller models weigh 3500 kilos and the larger models 4500 kilos.

The chassis design offers excellent ground clearance, which has traditionally been an important feature for Valtra owners who use their tractors for forestry, snow ploughing and harvesting operations.

The new A4 Series has 12 forward and reverse gears in two groups plus an optional creeper gear.

The forward-reverse shuttle is Valtra's well-respected HiTech power shuttle. The three smallest models offer two PTO speeds, while the four larger models have three. All A4 Series models are four-wheel-drive.

The operator can adjust the aggressiveness of the HiTech power shuttle while Valtra's traditional AutoTraction and HiShift features minimise the use of the clutch pedal.

The hydraulic output of larger models is up to 98 litres/minute, which is extremely powerful for this size of tractor.

The larger models also have a lift capacity of 5.2 tonnes with the linkage operated using Valtra's precise AutoControl.

Cab design

The A4 Series features a brand new cab design that offers the maximum space in this class of tractors. The new cab is both comfortable and ergonomic, making the tractor pleasant and easy to use. Electronic controls for the 4WD, diff lock and power lift fully support excellent ergonomics.

Visibility from the cab is excellent through 360 degrees.

The driver's seat swivels 180 degrees, and all controls are laid out logically making them easy to learn and use.

Almost half of all Valtra A and N Series tractors are ordered with factory-fitted front loaders.

The new A4 Series is ideal for loader tasks, and new G Series front loaders are available with either electronic or mechanical control. Serial production begins this summer.
