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.
