The Massey Ferguson MF 6445 is a tractor from the Massey Ferguson 4WD Tractor series. The engine draws 91 hp (67.1 kW) from 4.4 litres. Rated output is reached at 2,200 rpm, so it works in the lower rev range.
Unladen weight is 4,150 kg.
Within the range, rated power spans from 10.2 to 375 hp; with 91.2 hp, the MF 6445 sits in the mid-field. Directly alongside are the 593 with 90.2 hp below and the 3645 with 92.3 hp above.
Massey Ferguson – other models: the collective page of tractors outside the named ranges, from the MF 35 and 135 through the 1000, 2000 and 3000 series to the MF 1200 (compact) and the 8700 S, 5 to 313 kW, Perkins, AGCO Power, Iseki and Simpson engines
This page gathers the Massey Ferguson tractors the register could not assign to a named range – from the classics of the 1950s and 1960s such as the MF 35 and MF 135 from Coventry to current compact tractors and big tractors. Massey Ferguson emerged in 1953 from the merger of Massey-Harris (Toronto) with Harry Ferguson's tractor company, whose three-point hydraulics with draft control became the world standard; since 1994 the brand has belonged to AGCO, which builds the tractors in Beauvais, France, and sources the compact class from Iseki in Japan. The brand's type logic changed several times: the three-digit types 130 to 1200 of the 1960s and 1970s order the size in ascending order, the four-digit 1000 to 8000 series of the 1980s to 2000s give the range in the thousands digit and the model in the remaining digits (MF 1250 as compact, MF 3060 as mid-range), and since 2005 two digits mark the range and the last two the power step – MF 5710 as a 5700 with about 100 hp, MF 8737 as an 8700 with about 370 hp; S and the suffix Dyna-VT denote equipment and stepless transmission. The engines come from Perkins (the AD3.152 and 1104 series), AGCO Power (formerly Sisu) in the big and Iseki, Simpson (India) and Kohler in the small models.

The register lists here 1,011 versions with 5.2 to 313 kW from one- to eight-cylinders of 1,123 to 8,419 cm³, PTO outputs from 19 to 290 hp, lift capacities from 540 to 9,950 kg, unladen weights from 670 to 12,000 kg, lengths from 2,480 to 6,200 mm and widths from 1,003 to 3,000 mm.
By unit numbers Massey Ferguson is one of the world's best-selling tractor brands, with strongholds in Britain, France, Scandinavia, Africa and South Asia, where the MF 240 and its Indian and Pakistani licence builds shape the market.
Used, the span is as wide as the brand: on classics originality and Perkins parts count, on compacts hydrostat and front loader, on the 5700 to 8700 operating hours, Dyna transmissions, electronics and exhaust aftertreatment; parts run through AGCO and Perkins.

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.
- 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.
