Zetor Serie-9 (UR-1)

The water-cooled four-cylinder diesel engine has a displacement of 3,456 cc and produces 58 hp, or 42.7 kW, at 2,200 rpm, with 190 Nm of torque. At 3,555 mm long, 1,853 mm wide, 2,445 mm high, with a 2,220 mm wheelbase and 2,810 kg weight, the tractor reaches a design top speed of 25 km/h.

Series 9 was designed as a versatile standard tractor for medium-sized farms and, at around 58 hp, covered a broad range of tasks from tillage to haulage. This line's wide distribution in the late 1970s made it one of the defining tractors of its era across many Eastern Bloc countries.

When buying a Series 9 Zetor, the condition of the clutch, the tightness of the hydraulic system and corrosion on the load-bearing sheet-metal parts, common after decades of use, matter most. As this line was built in large numbers, parts for the engine, gearbox and axles remain comparatively easy to source today. A test run under load also shows whether the hydraulic pump still builds enough pressure for the three-point hitch, and whether the clutch engages smoothly across its full travel.
