Czech truck Škoda 706 — one of those cars that became a symbol of the era. Produced from 1961 to 1988, this tractor is still found on the roads of post-Soviet countries, which indicates its phenomenal survivability. Originally designed as a universal platform for military and civilian needs, 706th model gained popularity due to its simplicity of design, maintainability and ability to work in the harshest conditions.
Today Škoda 706 is not just a rarity, but a full-fledged working tool for small carriers, farmers and retro technology enthusiasts. Its traction characteristics, despite its modest power by modern standards, allow it to cope with trailers weighing up to 12–14 tons, and the diesel engine Škoda 706 R famous for its "indestructibility". In this article, we’ll look at why this truck is still in demand, what its weak points are, and how to choose a vehicle that will last for decades.
Technical specifications of the Škoda 706: what's under the hood?
The heart of the tractor - diesel engine Škoda 706 R volume 11.78 l air cooled. This engine, developed back in the 1950s, has become a legend due to its reliability and ability to run on fuel of questionable quality. The basic version gave 130–140 hp, but later modifications (for example, 706 RT) brought the power to 160–180 hp.
Gearbox - mechanical, with 5+1 steps (five-speed + range), which allowed the tractor to feel confident both on the highway and off-road. Suspension: dependent, on springs, with hydraulic shock absorbers. The brake system is drum type on all wheels, with a pneumatic drive. For its time, this was a progressive solution, although by modern standards the braking distance leaves much to be desired.
- 🔧 Engine: Škoda 706 R, 6-cylinder, air cooling,
11.78 l - 💪 Power:
130–180 hp(depending on modification) - ⚙️ Gearbox: 5+1, mechanical with range multiplier
- 🚛 Load capacity: up to
12–14 tons(with trailer) - ⛽ Fuel consumption:
22–28 l/100 km(depending on load)
A unique feature of the 706 is the ability to operate on kerosene or a mixture of diesel and oil (in emergency situations), which made it indispensable in conditions of fuel shortage. However, modern copies require high-quality diesel to avoid problems with fuel equipment.
Modifications of the Škoda 706: which tractor to choose?
For almost 30 years of production several modifications were released Škoda 706, differing in purpose, power and layout. The most common versions for civilian use:
| Modification | Purpose | Power (hp) | Features |
|---|---|---|---|
| Škoda 706 R | Basic version | 130–140 | Classic tractor with wheel arrangement 4×2 |
| Škoda 706 RT | Off-road tractor | 160–180 | Reinforced frame, all-wheel drive (6×6 in military versions) |
| Škoda 706 MT | Dump truck/platform | 140–160 | Short base, designed for construction work |
| Škoda 706 RTO | Tractor for heavy trailers | 180 | Extended Cab, Heavy Duty Hitch |
The most popular version for transporting goods is 706 RTO — it was equipped with a more powerful engine and a reinforced frame, which made it possible to tow trailers weighing up to 20 tons (in some configurations). If you need an off-road tractor, you should pay attention to 706 RT with all-wheel drive, although such examples are less common and more expensive.

Advantages and disadvantages of the Škoda 706: is it worth buying?
Like any technology with a half-century history, Škoda 706 has its pros and cons. Let's look at them in detail so you can make an informed decision.
✅ Pros:
- 🔨 Indestructible design: The frame and motor can withstand extreme loads.
- 💰 Low cost: prices for used copies start from
300–500 thousand rubles.. - 🛠️ Maintainability: spare parts are cheap, many parts are interchangeable with other Czech trucks.
- 🌍 Patency: versions with all-wheel drive (
6×6) cope with off-road conditions no worse than modern SUVs.
❌ Cons:
- 🚗 Archaic ergonomics: The cabin is cramped, there is no sound insulation, and the controls take some getting used to.
- ⛽ High fuel consumption:
25–30 l/100 kmwhen fully loaded. - 🛑 Weak brakes: The drum system requires frequent adjustments.
- 📉 Low speed: maximum speed -
70–80 km/h, which is not suitable for long-haul flights.
⚠️ Attention: Upon purchase Škoda 706 Be sure to check the condition of the frame for corrosion - this is the most vulnerable spot. Particularly affected are specimens operated in aggressive environments (for example, chemical plants).
How to choose a Škoda 706: checklist before purchasing
When inspecting a used one Škoda 706 Please pay attention to the following criteria:
☑️ What to check when buying a Škoda 706
Pay special attention engine: During a cold start, there should be no blue smoke (this is a sign of worn piston rings) or knocking noises (possible problems with the connecting rod bearings). Also check the compression in the cylinders - it should be at least 24–26 kg/cm² in all cylinders (dispersion no more 2 kg/cm²).
It wouldn't hurt to check braking system: Press the brake pedal and hold it for a minute - if the pedal “falls”, the brake master cylinder needs to be repaired or the cuffs must be replaced. Also inspect cardan shafts for play - this is a common problem with high-mileage vehicles.
If the seller claims that the engine is "overhauled", ask to see receipts or documents from the workshop. Often, “capital repair” means replacing only the gaskets.
Operation and Maintenance: How to Extend the Life of a Truck?
Škoda 706 does not require complex maintenance, but there are several nuances that will help avoid costly repairs:
- Oil: use mineral or semi-synthetic oil with a viscosity
15W-40(for example, Lukoil Standard or Rosneft Diesel). Synthetics are not recommended due to the risk of leaks from old seals. - Fuel: in winter, add anti-gel (even if the seller claims that “everything will be fine”). Diesel with a high sulfur content reduces engine life.
- Brakes: every
10–15 thousand kmcheck and adjust the clearances in the drums. Worn pads can lead to overheating and warping of the drums. - Electrical: The contacts in the fuse and relay box oxidize - clean them once a year.
One of the most frequently asked questions is how to increase engine power. Some owners install a turbine from Tatra T3, but this requires modifications to the cooling system and fuel pump. A safer option is to replace the camshaft with a sports one (for example, from Škoda 706 RT later issues), which gives an increase in 10–15 hp.
⚠️ Attention: Never pour into Škoda 706 modern motor oils with low ash content (for example,CJ-4orCK-4). They contain additives that attack old seals and gaskets aggressively, causing leaks.
What to do if the engine is misfiring?
If the engine starts to stall, check:
1. Condition of the glow plugs (even if the engine is diesel, they are used for cold starts).
2. Compression in the cylinders - low compression in one of them is often the cause.
3. Fuel injectors - they can be washed in an ultrasonic bath or replaced with new ones (the cost of one injector is approx. 3–5 thousand rubles.).
If the problem persists, the cylinder head may need to be repaired.
Prices for Škoda 706 in 2026: where is the best place to buy?

In Russia, the most profitable offers are found in Central and Volga districts, where these trucks were actively used in agriculture.
When purchasing through auctions (for example, Auto.ru or Avito) be careful: sellers often hide problems with documents or the condition of the frame. It is better to inspect the car in person or hire an independent expert. Average diagnostic cost Škoda 706 in the service - 5–8 thousand rubles., but this will save you from unpleasant surprises.
Before purchasing, check the VIN number through the traffic police database - many Škoda 706 were officially scrapped, but continue to drive with “gray” numbers.
Owner reviews: real operating experience
Opinions about Škoda 706 They are divided: some praise it for its reliability, others criticize it for its archaic nature. Here are some real reviews:
Igor, owner of dump truck 706 MT (2019–present):
“I bought it for 450 thousand rubles three years ago. During this time, I only replaced the battery and brake pads. The engine never failed, even when I had to carry 15 tons of crushed stone. Consumption is 26 liters per hundred, but for such a car this is normal. There is one minus - it’s cold in the cabin in winter, the stove is weak.”
Alexey, carrier (706 RTO, 2021–present):
"I took it for transporting equipment on a trailer. Pros: it pulls well, spare parts are cheap. Cons: the brakes are terrible, on a wet road it stops only with a rebuke of will. I can’t accelerate the speed above 60 - the whole cabin starts to shake. But for my money, this is the best option."
Many owners note that Škoda 706 perfect for local transportation (up to 100–150 km), but is not suitable for intercity flights due to low speed and poor sound insulation. Also often mentioned is the problem with electrician - over time, the wires become fragile and have to be replaced.
