Valtra showed the first of its new A series tractors at SIMA 2017, and last week it launched the whole range. The launch of this new range means all the Valtra series of tractors – the A, N, T and S – are now in their fourth iteration. This can be seen in the model numbers as they all end in four. The range starts at 75hp and goes up to 130hp. The three smaller models in the seven-model range come with a gutsy three-cylinder engine.
