Steyr has introduced the Profi 4135 Natural Power tractor equipped with a turbocharged mono-fuel compressed natural gas (CNG) engine. The engine is from Fiat Powertrain Technologies (FPT), a sister company in the Fiat group with Steyr.
The Profi 4135 is powered by a 3.0L, 4-cylinder natural gas engine producing 136hp and maximum torque of 542Nm (400lb-ft) at the transmission input shaft. Gas storage is in 9 separate fuel tanks with a total capacity of 300 liters.
The tractor is fitted with a 17 x 16 four-range powershift transmission and has a top speed of 50 km/h (31 mph). It is also equipped the with all of the features found on the standard Profi series, including load-sensing hydraulics delivering a flow rate of 113 liters/min, up to seven remote connections and an electronically-controlled rear hitch with a lifting capacity of 7,864 kg (17,337 lb). The 540/540E and 1000 rpm power take off with Auto PTO and an S-Tech 300 ISOBUS-compatible monitor are also part of the standard equipment.
As the tractor can be powered using refined biogas, Steyr engineers point out that this kind of drive concept is particularly suited to those farms that have their own biogas plants.
Steyr has also launched a line of diesel-powered Profi tractors with ecotech, a new emissions-reduction system.
