The Zetor 5511 is a rear-wheel-drive agricultural tractor manufactured in Czechoslovakia. Production of this model took place in 1966, with a total of 37,535 units built. As a four-cylinder, water-cooled diesel tractor, it represents a solid construction for its time. The machine is built using a unitary construction design, ensuring a compact and robust structure. With a maximum speed of 30 km/h, the tractor is suitable for use on fields and roads without exceeding typical speed requirements for road traffic.
The output of 55 hp at a rated speed of 2,200 rpm provides sufficient power for common field operations and the operation of mounted implements. A wheelbase of 2,257 mm and ground clearance of 420 mm allow for good stability and traversability on uneven terrain. The weight and dimensions of 3,710 mm in length, 1,833 mm in width, and 1,620 mm in height ensure a balanced weight distribution, which is adequate for most agricultural tasks. A turning radius of 3,970 mm permits relatively agile maneuvering on small areas and in tight yard spaces.
Within the model range, the Zetor 5511 occupies a specific position defined by its power class of 55 hp. It represents a mid-range category in the Zetor tractor lineup, designed for various agricultural holdings. The production figure of 37,535 units demonstrates the significance of this model at the time. The tractor is particularly suitable for tasks requiring moderate power and good maneuverability, without the need for the higher complexity of a four-wheel-drive system.
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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
