Brand "Cascade" - history of emergence and development
Motoblocks "Cascade" are produced by a Perm holding company that develops transmissions and gearboxes for helicopters - OJSC "Perm Motors". The holding began developing walk-behind tractors in 2006, launching the production of not only garden machines, but also four-stroke single-cylinder engines.
Today, Cascade walk-behind tractors represent one of the largest segments of low-power agricultural machinery. Many modifications are available to buyers, with different engines, types of steering columns and gearboxes. All Cascade walk-behind tractors are developed and assembled at a plant that assembles aircraft equipment, which is why their build quality and functionality are so high.
The first representatives of the Cascade series were equipped with DM68 engines, which were produced by the Kaluga Machine-Building Plant. Subsequently, DM68 increasingly began to be replaced with foreign analogues from manufacturers from China, Japan, and the USA.
The DM68 engine has been produced for more than 20 years. During its existence, the motor model has been improved. Several modifications were released, however, now Cascade walk-behind tractors are increasingly equipped with engines from Honda, Briggs & Stratton, Lifan.
The power of walk-behind tractors is approximately the same and ranges from 6 to 7 horsepower. Next, we will look in more detail at what modifications and types of Cascade walk-behind tractors exist today.

- The flat cutter removes weeds between the rows, chopping the roots;
- the plow makes cuts of different widths and cultivation depths depending on the size of the ploughshare;
- The rake removes the remains of tops and debris.
Equipping the Cascade walk-behind tractor with a trailer will allow you to transport goods over short distances. Connecting the appropriate drive units will turn the walk-behind tractor into a hay mower, snow blower, water pump, potato planter, and feed crusher.
Firework
Among the large selection of garden tools, the Salute unit is the cheapest today. The interesting thing is that if a Chinese engine is installed on it, then it fails much earlier than the Salyut unit itself.
If you want your mechanical assistant to serve you longer, it is better to install on it a motor from such well-known companies as Briggs & Stratton (America), Honda and Robin-Subaru (Japan), Lombardini (Italy).
However, it is better to purchase a motor from these manufacturers with a professional status. It will, of course, have a higher price, but it will serve you reliably and for a long time. For the Salyut walk-behind tractor, a Japanese HONDA “GX” class engine is better suited. It has excellent quality and long service life.
Choosing an engine for a domestic walk-behind tractor
Neva walk-behind tractors are in constant demand among summer residents and owners of country houses. Most models are multifunctional and can be supplemented with attachments. In order for the engine to cope with the increased load, especially when it comes to hard ground, a more powerful motor is required.
For the Neva MB 2K walk-behind tractor version, there are domestic DM-1M engines with a rated power of 6.2 or 7 hp.
For the version of walk-behind tractors Neva MB 2C, 3C. If you choose imported equipment, then there may be several options. Engines for Subaru walk-behind tractors in the EX-17D series have a power of 6 hp, in the EX-21D series - 7 hp. They are effective in any operating conditions under any load. Honda units with power from 6 to 9 hp. are an excellent alternative and easy to maintain. Their analogues will be the Chinese Sadko Lifan models and Bulat models with a reduced chain gearbox, for example Bulat BT170F-L. It allows for improved traction performance at low rpm, while the bolt pattern and shaft diameter are ideal for replacement.

One of the most widely used engines. Lifan 168. It has an engine capacity of 196 cubic centimeters and runs on gasoline. Power. 7 horsepower, air cooled, so they can only run for a short time.
To ensure the service life of the Lifan engine, after installing the Chinese engine, it is necessary to constantly fill in fresh oil and carry out maintenance.
Installing the motor is simple and does not require modification of the frame mount.
Fluid replacement work is carried out as follows:
- with the engine turned off, unscrew the drain plug located on the pan;
- drain the oil from the system;
- tighten the stopper;
- add new oil;
- warm up the engine;
- check the level and top up if necessary.
B.&S I/C
Motor B can also be installed.&S I/C, related to modern models and popular in everyday life. They are often used on cascade blocks.
This is due to the following engine features:
- 7 horsepower;
- enhanced transmission;
- enlarged combustion chamber;
- minimal noise during operation;
- high functionality even at low temperatures.
Vanguard ov
The imported Vanguard OHV engine is also one of the powerful engines that can be installed on the walk-behind tractor of this manufacturer and can perform all the necessary tasks. This engine has a power of 7 horsepower.
Operating and Maintenance Instructions
Cascade walk-behind tractors are presented in a wide range of different modifications. Thanks to this, they are used on agricultural plots of various sizes. With proper use, Cascade walk-behind tractors can last for a long period of time. However, you need to know how to properly maintain and repair these machines.
Walk-behind tractors Cascade
If you purchased a Cascade walk-behind tractor, you should read the operating instructions before starting operation.
When purchasing this machine from the factory, it must be included as standard; if you purchased it second-hand, then ask the old owner to provide an instruction manual for the Cascade walk-behind tractor. However, this is a little book that sometimes tends to get lost. Now you can find an electronic version of the instructions on the Internet.
Here are a few facts that anyone who owns this equipment should definitely know.
Oil and fuel
Engine Lifan-170F
Every owner should know what oil and fuel his Cascade walk-behind tractor works with.
Regardless of what kind of engine you have (Russian-made or Chinese Lifan), you must use only high-quality clean fuel AI-92 or AI-95. Do not use old or dirty gasoline. It can clog the fuel system.
Fuel is taken from the gas tank not from the bottom of the tank, but a little higher. This prevents dirt and dust from entering further into the carburetor, but it simply settles to the bottom.
Changing the oil in the engine of the Cascade walk-behind tractor:
According to the instructions for use, it is recommended to use Soviet oils in accordance with GOST. However, the time of the USSR has already passed, and now you can find higher quality imported motor oils with improved characteristics. In summer, you can use 15W-40 series, and in winter, semi-synthetic 10W-40.
The oil should be changed every 20 hours of operation of the Cascade walk-behind tractor.
The situation is similar with the transmission. The manufacturing plant recommends using Soviet TAP-15v or TAD-17i. However, 75W-90 or 80W-90 can be used instead.
To change the transmission oil, tilt the walk-behind tractor back and pull out the plug. Before doing this, place the container for drainage. Excavation causes great harm to the soil, so you should not pour it there.
Control levers are lubricated with Litol or Solidol.
First launch and run-in
The successful use of the walk-behind tractor in the future depends on the correct start of use. And an important stage is running-in.
These are the first hours of operation of the new device. In this way, the parts rub against each other and fit neatly into the grooves, so it is not allowed to heavily load the device at this time. The highest load should be half the maximum power. Otherwise, parts may fail before full operation begins.
If you are the first owner of a Cascade walk-behind tractor, then fill the crankcase with oil! It is not included in the factory configuration. And if you forget to fill it, there will be excessive friction, and the parts will fail again.
Since Cascade walk-behind tractors are representatives of a professional family, when purchasing it the owner expects it to work for a long time and help in carrying out agricultural work, and do not forget about running it in before starting.
Major breakdowns
Cascade walk-behind tractors have gained immense popularity due to the large number of compatible attachments and easy maintainability. You can easily configure and repair almost all parts of the equipment.
The most common reason for parts failure is their natural wear and tear. In order for the walk-behind tractor to serve for a long time, it is necessary to carry out tuning and regular scheduled technical inspections.
The main malfunctions include:
- Problems with spark plugs (contact came loose, gap changed, oxidized)
- Lack of oil (you need to check its level before each trip);
- The gasket on the cylinder is worn out;
- Dirt and debris have entered the fuel system (so gasoline does not flow into the carburetor);
- The tension of the chain or belt on the pulley has changed (as a result, the torque changes).
Let's take a closer look at the main breakdowns and ways to repair them.
- The transmission gets very hot during operation
The main reasons for this behavior are worn bearings, friction, lack of gear oil or its poor quality. The first thing you should try is to replace the transmission oil with new one. If this does not help, then disassemble the transmission and look at the condition of the bearings. Most likely, one of them has failed.
- The walk-behind tractor does not work smoothly
If the engine is running stably, but the Cascade is slipping or breaking out, look at the condition of the tread on the wheels. Most likely it has worn off. It is not allowed to work on tires that are too worn. If the treads are fine, the reason may be different tire pressures. And because of this, the walk-behind tractor will constantly move in one direction and behave incorrectly.
- Walk-behind tractor Cascade vibrates during operation
This nuance occurs when the attachment is connected incorrectly or is not fully secured. Before starting operation, you should always check the bolted connections and the reliability of their fixation.
- The engine is difficult to start
There may be several problems here:
- Initially, carry out a visual inspection for damage;
- If everything is fine, check if there is gasoline in the gas tank (there should be more than half of it and of good quality);
- If the walk-behind tractor is on an inclined plane, then place it on a flat surface;
- Check the entire fuel system and whether there is fuel supply throughout the entire line;
- Inspect the ignition system to see if there is a spark;
- Check the carburetor and try adjusting the fuel mixture.
