BB-Umwelttechnik - Double-blade Mowers
Double-blade mowers are an essential tool in modern agricultural practices, designed for efficient and precise mowing of grasslands. Unlike single-blade variants, double-blade mowers cut with two overlapping blades, resulting in a cleaner and more uniform cut. These mowers are particularly effective in terrains where consistent grass length is crucial for subsequent agricultural processes or livestock management. The enhanced cutting mechanics reduce the workload on the mower engine, potentially leading to longer machine life and lower operational costs. They are also designed to be adaptable and are suitable for various grass types and densities. This makes them a versatile choice for farmers who require both reliability and efficiency. BB-Umwelttechnik, a company known for its innovative approach to agricultural machinery, provides options that integrate durability with advanced technology, addressing the diverse needs of the agricultural sector.
Minimum power requirement
The power requirement of less than 2 hp per meter of working width measured by the Federal Institute for Agricultural Engineering (BLT) in Wieselburg, Lower Austria, illustrates how little energy is needed to mow effectively. A double-blade mower combination with 9 meters has a power input of 18 hp, a disc mower requires about 5 times that amount of drive power.
Minimum ground pressure
Double-blade mowers are significantly lighter than rotary mowers due to their design. They have a weight of about only one third of that. Using double-blade mowers can prevent soil compaction and grass sward damage.
Improved regrowth behavior and cutting pattern
In rotary mowers, the forage is cut off by the fast rotating blades. The double-blade mower cuts off the plants with a shear cut. This results in a straight cut, which significantly improves the regrowth of the plants.
Clean forage
Forage contamination is significantly lower when mowing with double-blade mowers than when mowing with rotary mowers because contamination, e.g. from a molehill, is not distributed throughout the forage.
Perfect forage deposit
During mowing with the double-blade mower, the forage is deposited completely homogeneously and evenly on the surface. The result is excellent drying behavior of the forage, and turning can be significantly reduced.
Safe stuff
With the double-blade mower, unlike rotary mowers, there is no risk of solid bodies, such as stones, being thrown away and damaging machinery or even injuring people.
Gentle for amphibians and insects
Double-blade mowers protect amphibians, insects and wildlife to a high degree. The number of injured and killed animals is demonstrably many times higher when mowing with rotary mowers. Furthermore, the body parts remain in the forage and cause various sicknesses in the animals that eat the forage.
Long lifetime of the blades
Since the correct ratio of travel speed and knife cutting speed is a very important factor for a long lifetime of the knives, we have developed a revolution counter with integrated operating hours counter, which always reflects the speed of the cutterbar drive. A table showing the parameters of the appropriate relationship between ground speed and cutterbar drive speed helps to adjust the rpm or the driving speed. Anything else is a “blind flight” when mowing with a double-blade mower and can cause significant damage to the mower due to incorrect speeds.
Cutting units with smooth lower knife
Tests in grass cutting have clearly proven that the service life of knives with a smooth lower blade is significantly higher than when using serrated lower blades.
Serrated bottom knives, on the other hand, have advantages in extremely stalky crops,such as hemp or reed.
Oil temperature monitoring
The use of oil coolers (optional) ensures an ideal oil temperature and consistent cutting performance, even on long and hot working days. All machines with their own oil supply are equipped with a thermometer as standard to always have information about the oil temperature.
Flip-away mechanism
When the cutting unit comes into contact with an object, the mower reliably moves
backwards / upwards. The pressure relief valve of the hydraulic drives is set so that the cutting unit stops if a foreign object gets into the blade. This prevents damage to the cutterbar.
Own oil supply
Basically, all BB – Umwelttechnik doubleblade mowers are equipped with their own oil
supply. A large-volume hydraulic oil tank, return flow filter and large-dimensioned pipes
ensure reliable drive of the cutterbar.
Optionally, the solo mowers can also be operated via the hydraulics from the carrier vehicle.
Flexible cutting heights from 4 cm
Depending on customer requirements, the mowers can be equipped with skids of different heights. From a minimum of 4 cm to a maximum of 20 cm, all cutting heights can be supplied.
NEW! Two different cutting heights are possible with one skid! For example, by turning the skid, you can switch between 5 and 7 cm cutting height.
Modular design
Due to the well thought-out modular design, many machines can be upgraded or converted without additional expense, e.g. a standard rear side mower
can be upgraded to a rear butterfly mower at any time.
