Checks
The sowing quality essentially depends on the adjustments and checks made prior to and during sowing,
as well as on regular servicing and maintenance of the machine. Before starting sowing, you should
therefore carry out all maintenance and lubrication work.
Checks Before and During Sowing
Machine
• Has the machine been hitched up correctly and are the coupling devices locked?
• Have the hydraulic lines been connected without being mixed up by mistake?
• Have the safety catches/wing lock pins been inserted for road travel and does the light system work
properly?
• Has the hydraulic system been switched to float position for sowing?
• Has the machine been levelled and the sowing depth correctly adjusted?
• Is the pressurized hopper tightly closed and sealed?
Cultivation Tools
• Are opener discs, scrapers, firmers, rollers, harrows (wear items) and other cultivation tools and
optional equipment still in a serviceable state?
• Are the cultivation tools discs and bearings still in usable condition?
• Are the friction bearings of the coulter discs still leak tight and have they been sufficiently sprayed
with corrosion protection oil at the end and the start of the season?
• Do the opener discs have sufficient pretension and do they all rotate freely?
• Are the scrapers still in good condition and correctly adjusted?
• Are packer rollers and packer bearings in good order?
Fan
• Is the hydraulic fan connected to a pressure free leak oil return line?
• Are the fan and intake grills clean?
• Is the fan tightly mounted on the shaft?
• Are fan speed and drive pressure not being exceeded?
Pneumatic System
• Are tram line valves installed in the correct seed lines for the tramlines?
• Has the tram line rhythm been adjusted and do the motorized valves close?
• Are the seed lines for tramlines completely closed and completely opened?
• Are the seed hoses free of sagging, water and other deposits?
• Are all air lines between fan and coulters leak tight and firmly connected?
• Does air flow out uniformly of all coulters?
• Has the air volume been set correctly on the fan? Does the seed not bounce out of the seed
furrow, or does it remain in the pipes and cause blockage?
• Is the gate in the distribution head in middle position?
• Is the gate in the venturi area in middle position?
Metering Unit
• Are the sealing lips and the brush seals in the metering unit still serviceable?
• In the case of small seed, has the cleaning brush been installed and is it in order?
