When MF concentrated its tractor production in France, alongside the new 6400 series, a cheaper 5400 series was introduced in the autumn of 2003. The technical differences to the more expensive series were minor. Both the basic structure of the tractor and the frame of the cab were the same. The instrument panel and some other controls were borrowed from the older 6200 series. Sound insulation was reduced, and the noise level was declared to be 76 dB, which according to test results was still an optimistic figure. The transmission was the 16+16 speed 2-range powershift used in earlier base models, with a mechanical reverser as standard. The hydraulics were based on an open system. A surprising cost-saving measure was replacing the draft arm sensing of the 6000 series with a push arm sensing.

The engines were Perkins’ new 1100 series. The 4-cylinder displacement had increased to 4.4 liters, and the cylinder head was crossflow. In the naturally aspirated engines of the two smallest models, the torque increase figures were quite weak. The more powerful ones were equipped with a wastegate turbo and had better performance figures. The most powerful model of the range, the 5465, had a 6-cylinder Perkins engine, which, unlike the 4-cylinder ones, was electronically controlled.

A hitch with electrical control and oscillation damping was standard. Optional extras were packaged into reasonably priced packages. The comfort package was popular and included air conditioning, an air-suspended seat, a passenger seat, and telescopic mirrors. Later, the package was expanded to include 100 l/min hydraulics, a brake valve, and additional lights. In other countries, the packages differed from those in Finland. The four smallest models were also available with a slanted nose. The two largest models had a rear end that was more robust than the others.

At the beginning of 2006, alongside the former Speedshift transmission, the Dyna-4 was introduced as an option, which, like before, had 16+16 speeds but featured a 4-range powershift and synchronization of the powershift when changing the range gear. Sound insulation was improved so that the actual noise level was now close to the promised 75 dB. The 5435 gained more power with the turbo. All engines now had a viscous fan. At the top of the range was the 5470, equipped with a 4-cylinder SisuDiesel. In it, the Dyna-4 was always standard. By the end of 2007, the Dyna-4 became standard on other models as well.
