Valtra A73
Series: Other models
The A73 is a tractor from the Finnish manufacturer Valtra. It belongs to the tractor group and is equipped with a 3‑cylinder engine. The engine delivers 78 hp (58 kW) and a maximum torque of 310 Nm. The displacement is 3 300 cm³ and the wheelbase measures 2 030 mm. The transmission provides 12 forward and 12 reverse gears, allowing fine speed selection. The fuel tank holds 74 l, supporting long work periods without frequent refuelling.
A power output of 78 hp enables pulling medium‑size implements and performing field tasks such as ploughing or mowing under moderate soil conditions. The torque of 310 Nm gives sufficient pulling force when starting heavy loads, especially at low engine speeds. The relatively short wheelbase of 2 030 mm contributes to compact manoeuvrability, useful on smaller plots or in tight field edges. The 12‑step forward and reverse gear range allows precise adjustment of travel speed to various operational demands.
A tractor of this size and specification is typically suited for medium‑scale agricultural work. The combination of moderate power, adequate torque and flexible gearing makes it appropriate for seeding, fertiliser application and light to medium pulling tasks. The large fuel capacity supports extended working cycles without the need for frequent tank stops.
Valtra – other models: the collective page of the Finnish tractors outside the named ranges, from the Valmet 600 and 6000 series to A, N, T and S, 10 to 313 kW, Sisu and AGCO Power engines from Linnavuori
This page gathers the Valtra tractors the register could not assign to a named range – the brand from Suolahti in central Finland that, as Valmet with state roots, built the first Finnish tractor in 1951, was renamed Valtra in 1997 after the sale to Sisu and has belonged to AGCO since 2004. The type logic: the Valmet ranges of the 1980s and 1990s – 500, 600, 6000 (Mezzo) and 8000 (Mega) – give the range in the first digit, -4 four-wheel drive and HiTech the equipment with electronic control; since 2000 Valtra has structured the programme in letter ranges, A for the compact class, N for the four-cylinders, T for the six-cylinders and S for the big tractors, with the following number as power class (N174 about 175 hp, T234 about 235 hp) and the suffixes HiTech, Active, Versu and Direct for transmission and equipment. The engines come from the company's own Linnavuori plant – first Valmet, then Sisu, today AGCO Power – three- to six-cylinders of 3.3 to 8.4 litres; the brand is known for the à-la-carte tractor the customer configures at the factory in colour and equipment, and for the forestry and municipal versions with the TwinTrac reverse-drive station.

The register lists here 646 versions with 9.7 to 313 kW from one- to six-cylinders of 400 to 8,419 cm³, unladen weights from 680 to 12,000 kg, gross weights from 1,100 to 16,000 kg, lengths from 2,970 to 6,090 mm and widths from 1,362 to 3,000 mm.
Valtra is market leader in Finland and Scandinavia and one of the big brands in Brazil, where AGCO runs a second Valtra plant; in Central Europe it is the tractor of forestry businesses and municipalities.
On used tractors, operating hours, Sisu engine and injection, HiShift shuttle and powershift (Versu) or stepless transmission (Direct), TwinTrac station, front loader and forestry equipment, rust on cab and mudguards count; parts run through Valtra and AGCO.

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.
- 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.
