With the setting season coming upon us and indeed it in full swing in some parts of the country, I took the opportunity to check out the latest in the mulch seed drill units from Pöttinger. Naturally I went for the biggest one in the shop and two hours later I had the Terrasem C4 hooked on to the T7 210 and we were on broken ground.
On the road, this drill is 3 metres wide, 2.5 metres tall and 8 metres long so it's big rig to have behind you. It comes off the scales at 6.5 tonnes empty and when it's folded out in the working position, it is 4 metres wide. Enough of the statistics, it's a big machine and typical Pöttinger, it's a good one. Let's start with the design of it. It's a 3 frame design, 2 sides fold down hydrauliclly and these outer frames have enough freedom of movement in work mode to follow the exact lie of the land.
Ideally, you need perfect soil preparation for exact sowing. This means a level surface finish with fine soil at seed level for uniform growth. On the Terrasem, soil preparation is taken care of by a two gang disc harrow with smooth or scalloped discs. Naturally, the discs are equipped with maintenance free bearings so less down time with the grease gun (thumbs up Pöttinger). In combination with the coulter between the discs, the seeds are placed at defined intervals, covered with a layer of fresh soil and packed down by the pressure wheels. It has a 90 degree turning angle so no time is wasted on headlands.
What will surprise you about this rig is the machine is supported by all wheels at the headlands. The chassis frame always remains in the same position, only the disc harrow and coulter rails lift. Each wheel has its own individual suspension system too so smearing on corners doesn't happen.
The model I had out was a top of the range c4 so it had its own integrated tank auger. The auger itself is on the hydraulics and will fill it's 3000 litre bin in 6 minutes. Add an expansion to the tank and it will hold 3950 litres. The blower is driven hydraulically also and drives a high output of air in the mid speed range so noise is kept to a minimum. The metering unit itself is electrically driven and controlled via Isobus or an on board radar sensor.
At the end of the day, if you are after a seed drill unit that literally does it all as efficiently as possible, this range of drills should be your first viewing. Quality build, simple to work the on board computer and minimum maintenance made this my favourite tillage day to date.
