ALLESTRUP MACHINE STATION IN HIMMERLAND HAS PURCHASED A SAMSON PG II 25 MANURE WAGON WITH PULL-OUT AXLE, WHICH BY DOUBLING THE TRACK WIDTH PREVENTS UNACCIDENTAL TRACK SHAPES IN THE PLAIN GRASS FIELDS.
It is here on flat grass fields in rotation that the SAMSON PG II 25 manure wagon with extension axle is most useful, says machine operator Alexander Jakobsen from Allestrup Maskinstation between Hobro and Aars.
As always, Alexander Jakobsen drives in fixed lanes for the machine station's many customers. And here it is part of Allestrup Maskinstation's service that there should preferably be no visible traces in the field after 25 tons of manure have just been added per hectare to push the yields of the next generation sky high.
Machine operator Alexander Jakobsen, Allestrup Machine Station, shows here how an extra track width of 800 millimeters on each side spares the flat grass field and eliminates rutting, even in wet ground.
If it is an old grass field with fixed and clear tracks, I do not push the axle out, because here there is often nothing to be gained by making the tracks wider, explains the experienced and agriculturally trained machine operator.
SHOT OUT WHILE DRIVING
On the three-axle SAMSON PG II 25 manure wagon, the extension axle is the middle one.
When I turn into the field and find the track, I activate the extension axles, which slowly and synchronously slide out 800 millimeters to both sides, thus doubling the track width and the part of the field on which the load is distributed, explains Alexander Jakobsen, who with a glance in the mirrors always in control of the function.
– Discreet and effective. During work in the field, the extension axle doubles the track width of the SAMSON slurry tanker and distributes the load over a combined track width of 3.2 metres.
Even when the axle has to be pushed back in line with the other wheels, this also happens while the cart is rolling.
After all, these are some powerful pistons that can easily push up a pile of soil if the wheels are pushed out while I'm standing still. After all, the output shaft carries just as much as the other two shafts, he explains.
DRIVING ON WET GROUND
At home at Allestrup Maskinstation, owner Henrik Nielsen tells about his motivations for acquiring a manure wagon with an extension axle.
This is actually the closest we'll get to a self-driving manure truck. With the extension shaft, we distribute the pressure over an area twice as large. Just as you do with a self-driving manure truck with a dogwalk, he points out.
Allestrup Maskinstation has seven SAMSON slurry wagons, of which there are also two wheeled wagons, which are particularly useful on hilly areas. The SAMSON wagon with an extension axle is especially used when manure is spread on plain grassland.
In addition to distributing the load over a wider track, it is essential that edges of soil are not pushed up into the sides of the track when we spread manure onto flat grass, he explains.
PREVENTS SCORE FORMATION
Henrik Nielsen, who has run his machine station from the address since 2005, has extensive experience with all the processes of grass silage, which keeps one of the machine station's three chopper jacks busy over the summer.
We know how, in certain cases, a heavy manure truck in wet soil can form small mounds of earth at the edge of the track just after a slough. It bothers both the swather and the rake and can ultimately help carry soil into the grass silage, which we don't want. And it just so happens that the day when it is very best to lay out manure and when we get the best nutrient utilization is also the day when the soil is wet, he points out.
- It is especially on newly laid plain grass fields that a SAMSON extension axle can spare the grass by distributing loads over a larger track width. It is important that there are no track edges where the swather and rake can drag soil into the silage.
800 MILLIMETER WHEEL
The machine station also experiences customers who ask to have the manure removed with the particular wagon that has an extension axle.
It is when, in a field, the edges of the tracks are unfortunately a little too high. In some situations, we can press the edges down again in the same workflow so that they don't bother later in the season, he explains.
Henrik Nielsen has gradually gained a lot of experience with manure application. Including self-propelled systems with dogwalk, which can distribute the ground pressure in wider tracks.
But we have to look at the price for manure application, and that's why today I only drive with tractor-drawn solutions. Already in 2005 I had a wagon with an extension axle. But back then the wheels could only be pushed out half as far. Today, we drive with 800 millimeter tires and the axle is therefore also pushed out 800 millimeters, he says.
24 METER SYSTEM
Today, Henrik Nielsen has 7 manure trucks, 4 25-ton and 3 28-ton manure trucks, as well as a single lorry to move manure with.
We collect 85 percent of the slurry with the trucks directly in the tank and thus only transport around 15 percent of the slurry out to the field with the truck. On the other hand, the truck moves a lot of manure during the year. In general, we drive with a 24-metre system, and virtually all customers have permanent tracks in the flat grass fields.
As mentioned, we have 2 wagons with wheel drive and it makes good sense around here, where there are quite a few hills. When we have now chosen to acquire a wagon with an extension axle, it also counts that the price is only one third of the extra price for a wheel drive wagon. And then I hope the customers will appreciate the situations where the quality of the manure distribution improves when it happens with a wagon with an extension axle, he says.
