INFORM Swath collection

INFORM Swath collection makes sense, especially with later cuts when forage yield tends to be lower. ally set to form swaths. “This means that on a working width of 3.6 m two swaths would be formed. The advantage here is that during subsequent turning, tractor wheels can be kept off the forage thus minimising contamination”, explains the mower specialist. Disc rotational direction can always be changed in the workshop, however. HOW FAST TO MOW? “OVER THE WHOLE SEASON MORE FORAGE IS HARVESTED IF ONE CUTS HIGHER.” PETER SCHULTZE, PRODUCT SPECIALIST FOR MOWING MACHINERY Mowing speed depends on the fields involved. With a new ley on an even field surface, 20 km/h is possible. Power requirement at the pto can be calculated as 15 to 20 HP per metre cutting width without conditioner, and approx. 25 HP per metre with. Mower suspension must be watched as well. This can be controlled mechanically or, nowadays with many mowers, also hydraulically - partly from the tractor seat. Downward pressure to aim for with disc mowers is 70 kg per metre working width. This optimises firstly the wear but at the same time ensures minimum damage to the grass sward as well as reducing contamination risk. Nowadays there’s a tendency towards more hydraulic components for adjustments of mower, turner and tedder – it’s a solution that eases operation and means the driver doesn’t always have to dismount to adjust suspension, for example. “The technical possibilities for optimising machinery adjustments are there nowadays – and they should be used”, concludes Peter Schultze. « 44

FACTS & FIGURES Continued from page 13 2.5 kWh electricity 300,000 9 km 0.6 l heating oil BIOGAS PLANTS A biogas plant with 500 kW capacity can increase the value of output from its respective region by as much as 300,000 € per year. BIOGAS 1 m 3 biogas produces on average 2.5 kWh electricity, or fuel to drive 9 km or as much heat as 0.6 l of heating oil. BIOFUEL 3.538 m t of biofuel with an energy content of 120 petajoules were used in traffic in Germany 2018. As in the previous year, biodiesel had the greatest proportion here with 72%. RENEWABLE ENERGIE In a single district with a good 250,000 population spending an annual 700 m € for energy requirements, using renewable energies could increase value of output by up to 350 m €. 350 m 45
