The Zetor 6340 belongs to the tractor group and is manufactured by Zetor. It is equipped with a power output of 73 hp (53.7 kW) and a 4‑cylinder engine with a displacement of 3,922 cc. The nominal engine speed is 2,200 rpm and the maximum torque is 247 Nm. Available transmissions are 10 V/2 R, 20 V/4 R or 10 V/10 R, providing a range of gear ratios. The fuel tank holds 70 L, the shaft speed is 540/1000 rpm and the overall height is 2,675 mm. The lift category is Cat II.
With 73 hp the engine delivers sufficient pulling power for medium field tasks, while the 247 Nm torque ensures responsive operation of attached implements. The choice of transmissions allows low ratios for torque‑intensive work and higher speeds for transport duties. A 70‑L tank enables long operating periods without frequent refuelling, and the compact height of 2,675 mm facilitates maneuvering under low obstacles.
The Zetor 6340 is suited for typical mid‑range applications such as field cultivation, pulling implements and intra‑farm transport. Its size and equipment make it an appropriate tractor for farms requiring a versatile machine for a variety of field operations.
Zetor — where the name comes from and how the ranges connect, models from 11 to 120 kW, engines including Caterpillar, Perkins, Zetor and Deutz
The brand name is a compound: the "Z" of the Brno arms factory Zbrojovka and the ending "-tor". It was there, in March 1946, that the first three Z 25 tractors left the line — an eightieth anniversary in 2026.

Order among the many Zetor types came in the 1960s with the unified UR I and UR II ranges. They brought more modern engineering and, above all, shared central components — the reason parts can be swapped across model boundaries. In the late 1960s the UR II joined the programme, designed for stronger machines and more demanding work.
Those lines still run today. The UR II range was revised and reached the market in 1998 as the Zetor Forterra. Around the turn of the millennium came the Proxima and Forterra ranges together with the modernised Major and Crystal — the generation carrying the brand through its recent history.
Anyone assessing an older model should therefore identify the base range first. A tractor from the UR II family is technically related to the Forterra, even with decades between them. That kinship decides how readily parts can be found — with a brand spanning eighty years of models, that is the most practical question of all.
Across the whole power range gathered here, 11 to 120 kW, the ISO 730 three-point linkage spans Category 0 on the smallest post-war models to Category II on the stronger series; the 540 rpm PTO speed remained, across the decades, the unchanged common denominator of every Zetor generation.

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.
- 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.
