Patriot;

When installing the engine, it is important not to exceed the permissible power. If you take a motor over 6.5 hp, the gearbox often begins to break down due to excessive loads.

The size of the belt for the Krot walk-behind norway mobile database is determined depending on the model. There are only three sizes that fit the models of this brand:

A13*900 – devices with an imported four-stroke engine;
A13*700 – suitable for the first modifications with a “native” engine;
A13*750 – suitable for most models with a gear pulley diameter of 150 mm.
The value “A13” means the belt profile, and the numbers 900, 750, 700 are its length.

Some models of the Krot walk-behind tractor are equipped with Chinese four-stroke engines

Standard cutters for the Krot walk-behind tractor have a diameter of 330 mm. They are mounted on the power take-off shaft. The choice of cutter model depends on the type of soil being processed. Thus, for medium and light soils, 1-2 pairs are used, and for virgin soil, three will be required.

Before cultivating the soil, it is necessary to lift the transport wheels and install a coulter on the hitch. It will regulate the depth of soil cultivation. If the soil being cultivated is dense and heavy, it is better to use goose foot cutters, and for soil with less hardness, cutters with four or three petals are suitable.
