Claas and Stage V, in Harsewinkel can say can say “mission accomplished!”. Here we provide some insights into the relationship between the German OEM and FPT Industrial, John Deere Power Systems, MTU and Yanmar. You will find the full article in the January 2021 issue of Diesel International.
Claas and Stage V. Let’s start with MTU
When mentioning Claas, puns are taken for granted. How did Claas prepare for Stage V? Certainly, with no hassle of standardization, but looking for specific and better designed curves for all work cycles of each machine family. Its agreement with MTU for an annual supply of between 4,000 and 5,000 units was pioneering. An agreement that encompasses all series from 1000 to 1500, in order to control harvesting (Lexion and Tucano) and chopping (Jaguar) operations, and anything else 4×4 open field tractors (Xerion) are designed for.
Fpt Industrial: NEF67 and Cursor9
FPT Industrial got onboard at the time of Tier 4 Final, with the Cursor 9 for the Axion 900, by shaping, for example, its torque curve according to the needs of the Axion 960, the top model. The announcement of the N67, which delivered 161 to 204 kilowatts in Tier 4 Final, dates back to 2013 and, as for the Cursor 9, it even goes back to 2008, at the time of IIIB.
The Deere for Torion
Let’s now drop the power level abruptly to talk about the wheel loaders by Torion, which for its three mid-range models (1177, 1410 and 1511), in collaboration with Liebherr, has reconfirmed John Deere solution for Stage V. In fact, the 4 and 6-cylinder engines, which are equipped with a 1.1 litre cylinder displacement, deliver 103 and 120 kilowatts at 2,000 rpm; while the top-of-the-range Torion 1511 delivers 138 kW at 2,200 rpm, that is a 12 per cent difference compared to its predecessor.
Low entry powered by Yanmar
The two smaller models (Torion 535 and 639) are powered by 46.3 kW and 50 kW Yanmar engines, which are Stage IIIB compliant. The hydrostatic transmission has two ranges: F1 from 0 to 6 km/hour and F2 from 0 to 20 km/hour. The (articulated loaders) tilting loads of the Torion 639 and 535 are 3.45 and 3.85 tonnes, respectively. An optimum centre of gravity and low heights (passage height of less than 2.5 metres regardless of the tyre type) ensure maximum stability even when working on uneven grounds.
