Zetor Proxima was introduced in 2004 as a replacement for the Super Vision. The old engines were replaced with larger, turbocharged units sourced from the Forterra. A 35% increase in torque was promised. The basic gearbox remained the same as before, but the shuttle-shift model gained two extra gears. Unlike most other tractors of the 2000s, the rear axle used a conventional portal-gear design. Four-wheel drive engagement was electric, and the front axle was still built by Carraro. Only one hydraulic valve was standard equipment. The power take-off still offered multiple speeds for stationary (local) use in different gears. A 1000 rpm PTO was available as an option.
The three-point hitch was always mechanically operated. The two largest models delivered a healthy 4150 kg of lift capacity. On the four-cylinder versions, the exhaust pipe ran up the cab pillar. The cab noise level remained at 83 dB.
