At the end of 1984, the 12-series models, i.e., the results of the "fifth modernization program," were introduced to the Finnish market. Additional power was added to the lifting device and hydraulic pump, although the performance figures remained rather modest and the lifting device was still slow as before. The engines featured new injection pumps. The rear axle housing was strengthened, and the clutch was hydraulically actuated and self-adjusting. In the 4-cylinder models, gear ratios were modified with fieldwork in mind, but the top speed still remained below 30 km/h. Sound insulation in the cabin was improved. The engine hood was beveled more than before. The ends of the drawbars were telescopic.

In the autumn of 1987, the updated successors to the 6211/6245 and 7211/7245—the 7711/7745 (73 hp)—were introduced in Finland, having been announced a couple of years earlier. The four-wheel-drive models (except the 5245) now featured hydrostatic steering and a locking differential on the front axle. Road speed was increased to 35 km/h, and the brakes were disc brakes. Towards the end of their production, four-wheel-drive versions of these models and the updated 5245 were also available with a 10+10 shuttle gearbox. The updates to disc brakes and hydrostatic steering did not apply to the 5245. The 1990 novelty was the turbocharged 7745 Special (81 hp) available as a retrofit. At the same time, a specially equipped 7745 Jubilee was also offered, which included, among other things, 1000 rpm PTO, radio, and a Grammer seat. However, the model 5211 R (35 hp) was not imported to Finland.
