The device of the walk-behind tractor Cascade

Each version of the device consists of 4 basic units: transmission, power plant, chassis and controls. The unit is often equipped with a variety of engines.

As for the undercarriage, it consists of a frame with drive wheels and assemblies mounted in it. The rulers of the Cascade walk-behind tractors are distinguished by the ability to independently determine the inter-wheel distance.
Moreover, the unit is often accompanied by powerful pneumatic wheels with aggressive treads. The creators of the technique also provided for the specifics of storing the object and supplemented the design with special metal stops. They can be very useful if you need to stop the device during a workflow.

The reliability of the transmission is beyond doubt, and its main task is the high-quality transmission of torque to the wheels from the engine itself. It is also an integral part of the process of determining the speed and rotation of the device. The chain reducer, clutch and 4-speed gearbox belong to the basic components of the transmission and are often housed in a special block.

Most models have multiple forward and reverse speeds for excellent maneuverability. The output shaft of the reinforced gearbox is located on bearings with a significant diameter, which steadily react to mechanical damage and the negative impact of various kinds of vibrations. A specialized belt drive allows the owner of the Cascade walk-behind tractor to install the necessary attachments.

It is worth noting that the system is controlled using the clutch handle, gear traction, steering wheel, engine, power regulator and carburetor air damper. The handlebar itself can be easily adjusted to suit the height of the operator, and the center of gravity is located relatively low.

Thanks to the indicated moments, it becomes easy to control the walk-behind tractor. This is also facilitated by the location of most of the controls directly on the steering wheel.

Particular attention should be paid to the steering column, which is quickly adjustable, allowing a person, even after several hours of active work with the Cascade walk-behind tractor, not to get so tired and adapt the basic control elements to personal wishes

It is important immediately after purchasing the device to carry out the correct running-in, control the oil and fuel level and not overload the machine, otherwise it will often start to fail and soon become completely unusable

Working at high speeds

Expensive models of walk-behind tractors are characterized by the presence of several operating speeds. On the one hand, this option makes it possible to optimize the process of planting, harvesting or processing the field. On the other hand, the functioning of cultivators largely depends on the quality of the belt. The first thing to remember is that the length of the product always meets the requirements specified in the passport.In second place is the requirement related to strength.

Constant switching of speeds does not have the best effect on the operation of the device. That is why it is worth abandoning the use of cheap and not always high-quality belts.

A cultivator is a technical tool that performs the following functions:

• weed control;
• plowing the soil;
• loosening;
• application of various fertilizers to the ground.

During intensive use, some units and parts of the unit may be damaged

... Therefore, it is necessary to purchase the necessary spare parts in advance (it is possible on the day of purchase of the cultivator itself). This will allow it to return to functionality immediately after a breakdown.

The main elements of the cultivator are a gearbox, levers, a fuel tank, a frame, a motor, a support, a wheel, as well as a working tool knife. The transmission of torque is provided by a gearbox, which is built into the engine.

The machine knives are designed to cut layers of soil, mix and grind them easily. Device management is effortless.

Outstanding representatives of the same reliable and high-quality equipment are cultivators, and. For more information about the work of the Mole cultivator, see the video:

, spark plug cap or starter pawl, it will take time to find the right part.

Belt

From time to time, when operating the Mole walk-behind tractor, you can notice belt slippage.

This problem can be avoided by installing 2 belts. Correct installation requires an oversized idler pulley.

The roller is placed on bearings. To improve the cultivator, you just need to remove the old roller and install a new one.

The unit uses drive belt A-750.

It is 750mm long, 8mm high and 13mm wide.

Product composition:

• cord;
• wrapping layer;
• technical vulcanic rubber.

The main task of the belt is to transfer torque from the motor to various components of the device. The belt is marked according to the size (mm). It can be used at temperatures from +30 to +60 degrees.

Attachments of the walk-behind tractor "Cascade"

• cutters that allow you to work the land on a strip with a width of 45 to 93 centimeters. If the land does not belong to the category of virgin or especially hard soils, then it makes sense to add two more additional cutters to the two standard cutters, more than doubling the strip of simultaneously cultivated land.
• hiller. Very handy and useful equipment, the value of which will be appreciated by anyone who has tried it in action.It not only destroys weeds in the inter-row space, but also sprinkles soil to the stems and roots of cultivated plants, helping them to develop and grow.
• flat cutter. It not only loosens the soil, but also crushes the roots of weeds, reducing labor costs for further weeding of the site.
• trolley trailer. Of course, the speed of movement of the walk-behind tractor is very low, but, in any case, it is better to transport bags of potatoes or other heavy or dirty cargo in a cart, and not drag them "on your hump". The same goes for construction waste, various tools and materials. The trailer is designed for a load of up to 600 kilograms.
