Valtra, a subsidiary of AGCO, has launched a new line of five S-Series tractors, ranging from 270 to 370 hp (201 to 276 kW) and 1185 to 1540 N·m (874 to 1135 lb·ft).
The S-Series has been developed closely with AGCO, which also controls Massey Ferguson, Challenger, and Fendt. Power for the S-Series comes from AGCO Sisu Power’s 84CTA-4V engine and is sent through a stepless transmission. The engine is an 8.4-L six-cylinder diesel, turbocharged and fuel injected. The power is adjusted depending on the model chosen. AGCO's new transmission is constantly variable, with the speed adjusted using the throttle pedal, a hand lever, or advanced automation. The chassis and the axles are also new.
While already meeting the 2011 emissions regulations, Valtra has gone further and added selective catalytic reduction as standard on the largest S352 and as an option on all other S-Series models except the S232, the lowest power tractor in the line. Urea-based AdBlue is sprayed into the exhaust gas to reduce the NOx emissions, improve fuel economy, and prolong engine oil life.
A new cab features seating for two and a small refrigerated compartment. Available options include an air-conditioned driver’s seat and Auto-Guide steering, which uses satellites to control the steering and accurately visit all areas of large fields, saving time and allowing the operator to focus on implement control. TwinTrac reverse-drive controls that allow the operator to swivel to face the rear are also optional.
The S352 tractor has a mass of 10,300 kg (22,710 lb), which can be increased to 14,320 kg (31,570 lb) using additional weights or 17,640 kg (38,890 lb) with double wheels. The rear linkage has a lifting capacity of 11 t (12 ton), and the front has 5-t (5.5-ton) capacity.
A choice of eight colors can be ordered, making Valtra the only company to offer color choices. Cab suspension is on all four corners, or a semi-active AutoComfort cab is optional.
Valtra has plants in Finland and Brazil that sell to the European and South American markets, and, in fact, it claims to be the second best-selling tractor brand in South America.
