Following in the formidable shadow of T series, Valtra has introduced a revamped ‘N’ with the same modern cab plus a Stage IV engine perched out front. We take a look at the 99kW/135hp (maximum output to ISO 14396) four-potter.
From a distance it is hard to distinguish the N4 series from its T4 sib, and even the sharpest-eyed haven’t a hope of reading the model badge. You have to be practically standing beside the four-cylinder tractor to notice the tiny but smart-looking model designation on the headlight, while a posh emblem on the door hinge informs you as to what transmission is in place.
Still, getting all close up and personal we see this month’s test tractor is an N134 Versu. Like the Active and HiTech models, it has the five-speed powershift transmission with a total of 30 ratios including creeper range, whereas the Direct tractors drive through Valtra’s own stepless box. The difference between HiTech, Active and Versu is all about their hydraulic specifications. But let’s kick off with the N’s pounding heart. Unfortunately, Valtra doesn’t reveal the engine’s rated power; instead the brochure only shows the maximum output of 99kW/135hp (to ISO14396, which does not include ancillaries). Then you need to add in the bonus of a boost function (up to 107kW/145hp) which kicks in for pto work, even when stationary, and when travelling over 11.5km/hr in range C.
The DLG test centre verified these stats for us on the dyno. With the boost function deactivated, the test team measured 89.9kW/120.5hp and, with the boost given the green light, 96.3kW/129.1hp — both very reasonable results. The same applies to the max torque of the 4.9-litre AGCO Power 49AWI engine, which put out 550Nm (boosted) — a top result for this horsepower band. This and a nearly 10% extra power and more than 27% constant power clearly make up for the rather average drive torque.
