The Cnh Steyr CVT 6145 belongs to the CVT - Zweite Reihe series. Production: 2003–2006. The engine delivers 147 hp (108 kW), has 6 cylinders, with a displacement of 6,597 cm³. Rated speed is 2,100 rpm. The machine is 4,740 mm long, 2,490 mm wide and 3,000 mm high. The unladen weight is 6,390 kg. The wheelbase measures 2,806 mm. Top speed is 40 km/h. Transmission: continuously variable. The engine is water-cooled. Tyres: front 540 / 65 R 28, rear 650 / 65 R 38. The fuel is Diesel / Rapsdiesel. Rated output across the Cnh Steyr range ranges from 65 to 240 hp; the CVT 6145 sits in the middle of that range with 147 hp. Its immediate neighbours are the CVT 6140 below it with 141 hp and the CVT 6150 above it with 150 hp. Rated output across the Cnh Steyr range ranges from 48 to 176 kW; here the CVT 6145 sits in the middle of that range with 108 kW. 28 Cnh Steyr models across 14 series are on record.

CNH Steyr CVT – the entry six-cylinder step with continuously variable transmission: CVT 6135 and CVT 6145, 101 to 108 kW, 6,597 cc, kerb weight 6,390 kg, rapeseed-diesel approved

Steyr was among the first tractor makers to offer a continuously variable transmission as standard, developed jointly with ZF and marketed in-house as S-Matic; the CVT range with the six-cylinder diesel bundles several power steps on this basis, here with the CVT 6135 and CVT 6145 at the lower end of this six-cylinder line-up. The transmission's control range fully replaces the classic stepped gearbox and lets travel speed be adjusted independently of engine speed.

The register lists 2 variants at 101 to 108 kW from a six-cylinder diesel of 6,597 cc, a kerb weight of 6,390 kg, a length of 4,740 mm, a width of 2,490 mm, a height of 3,000 mm and a rated 2,100 rpm; both models are approved for rapeseed diesel.

With a CVT gearbox and around 135 to 145 hp, these models target larger arable farms and contractors who switch frequently between field work and road transport; competition comes from the CVT models of sister brand Case IH as well as from Fendt Vario and John Deere AutoPowr.

Buying a CVT tractor, the condition and oil-change intervals of the continuously variable transmission matter above all, along with hydraulic tightness, the state of the six-cylinder diesel including the turbocharger, and the electronics and sensors of the transmission control; servicing and parts run through the CNH dealer network for Steyr and Case IH; a test drive across the full control range shows whether the transmission shifts smoothly and without jerking.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.
Compare the data plate and chassis number with the papers.
Check the weights in the papers against the figures here — attachments change them.
Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
Shift the gearbox cold and warm — jumps only show up at temperature.
Load the hydraulics and watch for sag.
Ask about parts availability for this build year — the running costs hang on it.
