MULCHER MZ three-rotor, semi-mounted rotary cutters with a working width of 4.5-5.8 metres are very popular machines that combine a high area capacity with low demand for the tractor towing power. The robust frame with hot-dipped galvanized body predetermines the rotary cutter to be maximally used in the most demanding conditions of an agricultural operation.

A semi-mounted rotary cutter with a working width of 4.5– 5.8 m designed for quality mulching of crop residue, unwanted tree seedlings and grasses, with a high daily output.
Mulching vegetation contributes to a balanced growth of above ground matter, processing ungrazed grass (bad quality fodder not grazed by the cattle), it promotes grass offsetting, and also prevents the development of weeds.
In this case, the rotary cutter crushes, shortens and evenly distributes the mulched material, which is then better incorporated into the soil and also decomposes faster. Mulching is also important for mechanical prevention of diseases and elimination of pests, such as the European corn borer.
Weeds and dispersed tree seeds do well in maintained land. To reduce their occurrence, the land needs to be mulched well to prevent seeding and other unwanted spread.
The MULCHER MZ semi-mounted rotary cutters are highly durable and designed for hard work. Hot-dipped galvanization of the machine provides high resistance to vegetation sap, collision with rocks, or weather conditions.
Quality mulching requires a large rotor diameter and high circumferential speed. The MULCHER MZ mounted rotary cutter is equipped with two pairs of shaped knives on the rotor to ensure excellent quality of work. The blades can be used both for mulching grasses and processing crop residue.
MULCHER MZ can be equipped with cover plates of the main frames. The plates are smooth and minimize the sticking of plant residue on the machine.
When compared with the standard model, MULCHER MZ can be equipped with a walking version of the central axle. The machine is then able to better trace any terrain unevenness and maintain the set working width. You can achieve an even better effect in combination with the tandem version of the side axles.
The transmission part of the MULCHER MZ semi-mounted rotary cutter is protected against damage (for example, in the case of a collision with a rock, etc.) with a friction clutch that automatically stops all the transmission processes. The cardan shaft connecting the tractor with the gearbox is equipped with a friction clutch.
The side wings of the MULCHER MZ rotary cutter can also be lifted, for example, when mulching unwanted tree seedlings along field edges. The wings work on a swinging arm and perfectly trace the unevenness of land to be mulched from −15° to +45°.
When manufacturing BEDNAR rotary cutters, we use high-quality cardan shafts by Walterscheid.
The main component is the fan that creates a stream of air and the wind straighteners direct air to the risk areas on the machine surface. The equipment prevents dirt and plant matter from sticking on the machine surface. It improves labour safety and reduces time spent with cleaning.
Counter blades that provide the final cutting of the mulched material are installed in the front part of the mulching area to increase the crushing effect. That easily increases the quality of material mulching.
The spreading deflectors ensure that the rotary cutter works perfectly as they evenly spread the mulched material. They prevent the formation of plant clumps and larger amounts of matter in one place.
The MULCHER MZ semi-mounted rotary cutter is equipped with replaceable armoured plates that protect the machine frame from damage. Moreover, each rotor is protected with its own cover, which enables to work in an extremely low position above the ground.

The rotary cutter is easily aggregated to the bottom or top tractor hitch. It can also be connected using the K80 ball pin.
Two pairs of bent blades provide an excellent cutting and crushing effect. There are two blade models available – grass and corn.
The central walking axle provides excellent terrain trafficability, and even better tracing when compared with the standard model.
They protect the rotor and enable to work in an extremely low position above the ground.
The side runners maintain the set working height.
They provide an outstanding resistance to aggressive vegetable saps or mechanical damage (e.g., collision with a rock).
It prevents dirt and plant matter from sticking on the machine surface and increases labour safety.
The device for continuous machine surface cleaning is mounted centrally on the machine to provide the best possible effect at work, and also compactness during transport.
“We decided to purchase the machine after we saw a demonstration in a grain maize stubble field and meadow grass. We tried competitive hammer cutters in the same conditions, but the quality of work did not meet our demands. Therefore, the MULCHER MZ 6000 rotary cutter was the obvious choice; it worked perfectly in the stubble field as well as in the meadows. Another decisive factor was that the rotary cutter with a working width of 6 metres does not need such a towing power as the competitive machines.”

We know that everyone has different requirements for the optional machine equipment and its expected use. Therefore, you can specify your MULCHER MZ semi-mounted rotary cutter to precisely match your needs.
We achieved double-crushing hard stalks, such as grain maize, sunflower, or oilseed rape, by combining the paddle-shaped blades mounted in the lower plane and straight blades mounted in the upper plane. The stalks are cut at two levels at the same time.
The paddle-shaped bent blades, cross-mounted on one plane, are suitable for mulching permanent grassland. The paddle-shaped knives create a suction effect, which lifts the grass run over by the tractor wheels and helps mulching the grass.
The main component is the fan that creates a stream of air and the wind straighteners direct air to the risk areas on the machine surface. The equipment prevents dirt and plant matter from sticking on the machine surface.
CROP RESIDUE MANAGEMENT
Processing crop residue after harvest is important for several reasons. Crop residue is a source of organic matter therefore it is not desirable to simply leave it in the field without attention. Crop residue may be unevenly spread which aggravates soil cultivation and the clumps facilitate the spread of diseases and breeding of pests.
