In a number of situations, Jacob Ravn, owner of Lunde Machine Station near Varde, has achieved an increased delivery capacity by reducing himself to a smaller-sized manure wagon.
- It may seem strange to bet on a SAMSON PG II 20 when the other two wagons at the machine station are larger, respectively a SAMSON PG 25 and a SAMSON PG II 31. But this is connected with a strategic change towards less field pressure and less hogwash on the country road. After all, both the farmers and I have an interest in improving our image during the manure season.
– And it works with the new SAMSON PG II 20 Genesis, because it only stays in the field and the slurry is now transported from the tank to the field with a buffer wagon. We are accepted by the other road users.
The adaptation and use of the buffer wagons together with the new SAMSON Genesis wagon has meant that Jacob Ravn has had to rethink the manure application.
- Firstly, we can now keep the SAMSON Genesis wagon in the field all the time. It has extra-large wheels and VF tires that run with low air pressure, which is gentle on the field. Next, I have acquired two used SAMSON PG 25 manure wagons that function as buffer wagons.
While the tractor driver is at home after another load with the second manure truck, the manure is transferred from the full buffer truck to the new SAMSON PG II 20 Genesis in the field.

– When the Genesis wagon and the three-tonne front tank on the tractor with the dumper have been emptied, the tractor driver with the full buffer wagon has arrived and has placed it in a suitable place in the field. He now disconnects the full wagon and connects to the empty buffer wagon and drives home after the next load. All this can of course only be done with the so-called Siwi Combi Hitch system on the tractor and the two SAMSON buffer wagons, explains Jacob Ravn.

Jacob Ravn has chosen to continue to have a pump tower on his buffer wagons for filling at home at the slurry tank to avoid having to go out and move a tractor pump every time a new tank has to be moved.
When the slurry has to be pumped from the buffer wagon in the field, Jacob Ravn uses the Genesis wagon's SAMSON Ejektor system, which is a suction and pumping system that moves the slurry into the wagon.
- It is a closed system that neither stinks nor smells much. And then we avoid having to reload the slurry in the same place every time, points out Jacob Ravn.
With truck transport and a large fixed buffer tank, we quickly create a muddy area in the field and, of course, also more driving in the field, because we cannot move a large fixed buffer tank all the time.
– With the SAMSON Ejektor suction system, the machine station's Genesis wagon can also pump slurry from a lorry from the biogas plant, which has the same connection system.
As one of the first with the combination of buffer wagons, Siwi Combi Hitch and a field-going SAMSON PG II 20 Genesis manure wagon for delivery, Jacob Ravn – after preliminary delivery this year of 55,000 tonnes of manure – has analyzed and calculated the capacities.
- When, with a distance of 1.5 to 2.0 kilometers to the tank, we deposit, for example, 50 tonnes of manure per hectare for corn this spring, one man in the field with the Genesis wagon and one man and tractor for the two wagons could maintain a capacity of 140 to 150 tons per hour. However, for shorter distances of less than half a kilometre, it is not worthwhile to use the buffer wagons, just as very large distances are naturally not suitable for tractor transport of the slurry.
- But in general, in our area with many large cattle farms, we have certainly been able to increase the capacity for manure application. And at the same time created a better image for the farmers vis-à-vis the surrounding community and the many tourists who drive on the surrounding roads, concludes Jacob Ravn.
According to Jacob Ravn, the advantage of using buffer wagons and keeping the delivery wagon on the field at all times is greatest with high allocations.
– It results in a lower load on the ground when delivery and deposition is done with a two-axle wagon with the large 194 cm high low-pressure tyres.
