ROTARY HARROW FOR PRECISE SOIL CULTIVATION

The KATOR KN is a model series of mounted rotary harrows with active working parts. The rotary harrow is especially suitable for seedbed cultivation in impermeable, hard, dry and heavy soils. In one pass excellent work result and quality-prepared seedbeds are guaranteed.

Key properties

A rotary harrow for even soil profile cultivation and quality seedbed preparation, especially in heavy, hard and dry soils.

ROBUST GEARBOX

For perfect power transmission.

The central shaft is the main part of the rotary harrow and the most used component. The connection between the special solid crown with an elongated case and a reduced central shaft (75 mm) provides for a perfect transfer of force between the gearbox and the cascade of gearwheels.

ONE ROTOR, THREE BEARINGS

A design that no-one else offers.

Each rotor is equipped with three bearings (the shaft is mostly surrounded by bearings). This system provides for perfect rotor stability and protects gearwheels, shafts and gaskets from damage. No other competitor offers three bearings per rotor.

QUICK BLADE REPLACEMENT

Easy replacement without the need for special tools.

A quick and easy blade replacement. Just pull out the safety pin, remove the pin and replace the blade. It is a system designed to be used without any special tools and equipment.

PROTECTION AGAINST STONES

Avoid rotor damage.

The special “STONE” equipment prevents stones from penetrating or sticking between the blades holder flange and the rotor. The bearing holder and cover are made from one part. The cover is screwed to the machine frame and the shaft turns inside the cover. This way, no foreign objects that could damage the gasket or bearing can enter the rotor area.

A LARGE NUMBER OF ROTORS PER METRE OF WORKING WIDTH

Perfectly cultivated soil.

The folding arrangement of the BEDNAR KATOR rotary harrow offers only 22.5 cm between rotors. A larger number of rotors per metre of the working width improves soil crumbling.

LEVELLING BAR

Prevents clogging and creating waves.

The rear levelling bar is very close to the rotors. This design is better for higher quality of soil levelling (a greater distance between the rotor and the rear levelling bar creates waves).

HIGHLY ROBUST FRAME

Stronger than in any other competing machine.

The bottom part of the main frame of the gearbox cascade of gearwheels is made of steel with a thickness of 12 mm. The main gearbox is not filled with oil but with a highly viscose grease that ensures reliable lubrication of the gearwheels. Also, the risk of oil leak into soil is eliminated in case of tub damage, such as puncture.

Spodní část hlavního rámu převodové kaskády ozubených kol je vyrobena z oceli o tloušťce 12 mm. Hlavní převodovka není naplněna olejem, ale vysoce viskózním mazivem, které zajišťuje spolehlivý chod ozubených kol. V případě poškození vany, například při průrazu, tak je eliminováno riziko úniku oleje do půdy.

EXTERNAL GEARBOX COOLING

A quiet operation, a long-lasting engagement.

The KATOR KN 6000 model and the KN_PROFI model series can be equipped with external gearbox oil cooling for intense long-lasting operation without overheating.

HIGH-QUALITY PTO SHAFT

By Walterscheid.

The KATOR KN rotary harrows have high quality PTO shafts by Walterscheid in various dimensions according to the model.

OUR INNOVATIVE TECHNOLOGIES

ONE ROTOR, THREE BEARINGS

Each rotor is equipped with three bearings (the shaft is mostly surrounded by bearings). This system provides for perfect rotor stability and protects gearwheels, shafts and gaskets from damage. The system provides perfect rotor stability and absolute protection from dust. No other competitor offers three bearings per rotor.

CARBIDE BLADES FOR HIGHER RESISTANCE

We recommend choosing the LONG-LIFE blades with carbide tips for higher resistance when used in abrasive soils.

WHAT DO THE FARMERS HAVE TO SAY?

“We started using the BEDNAR KATOR KN 7000 Q PROFI rotary harrow at our farm for soil cultivation in difficult conditions in fields that are hard to cultivate. We tested what the machine can do and in my opinion it is a high-quality machine. Thanks to the high number of rotors per metre of working width the clod crushing is much better than in competitive machines. I am very pleased with the machine and so we also purchased another BEDNAR rotary harrow with a working width of 8 metres.”

AGRONOMICAL GUIDE

SEEDBED CULTIVATION
Soil preparation is an important operation for the formation of a uniform and balanced seedbed prior to crop establishment. Each crop and field requires different soil preparation based on the climate, or the chosen date of cultivation. The aim of the seedbed cultivation is to create an ideal soil structure in the field, with a harder bottom and loose top soil layer, to level the field after previous operations, and to open, warm up and aerate the soil profile for even crop emergence.
