SAMSON AGRO’s most popular slurry tanker, the PG 25, is now being replaced by the PG II 25, which is a brand new slurry tanker. PG II 21 replaces the PG 21. The rest of the PG series is being discontinued...
The two new slurry tankers from SAMSON AGRO are structured in the same manner as the slurry tankers in the PG II series. This means that they have the same supporting structure, undercarriage, drawbar frame and lift. They also have the same options as in the PG II series.
In order to maintain the same good weight distribution as in PG 21 and PG 25, the engineers at SAMSON AGRO have maintained the length on the PG II 21 and PG II 25, to match the original length of the PG 21 and PG 25. The location of the axles and wheels on the tank are also the same as on the PG 21 and PG 25. We can therefore say that the PG II 21 and PG II 25 are a new generation of the PG 21 and PG 25.
The PG II series was first introduced in 2013. Three 3-axle sizes were launched, the PG II 27, PG II 31 and PG II 35. The following year, in 2014, SAMSON AGRO introduced three 2-axle sizes, the PG II 16, PG II 18 and PG II 20. The two new sizes, PG II 21 and PG II 25, means that SAMSON AGRO can offer its customers even more options, so that they can match their particular requirements for a modern slurry tanker, which is also characterised by a high level of operating reliability and a high resale value.
Prepared for the future
Like the other model sizes in the PG II series, the two new PG II slurry tankers are equipped with stronger axles and brakes. The dimensions of the brakes have been increased from 406x140 mm to 410x180 mm. The axle profile has been increased from 110x110 mm to 150x150 mm. An integrated speed sensor has also been fitted to the wheel axles, where there was previously an external sensor on the wheel axles on the PG slurry tanker. This improves speed measurement. The brakes are approved to drive at 40 km/h in Germany.
The tank on the 3-axle PG II 21 has been reduced slightly in size compared to the PG 21. It therefore has the lowest axle load of any PG II slurry tanker.
All PG II slurry tankers have a maximum transport width of three metres and a maximum transport height of four metres.
If you are interested in being able to measure the nutrient content of the slurry, it is possible to buy a PG II slurry tanker that is already prepared for fitting a John Deere NIR sensor. This provides many exciting prospects for the future spreading of slurry, including precise allocation of slurry based on its nutrient content, the crop’s requirements and variations in soil nutrient status. It also allows for the selling of slurry with precise specification of nutrient content.
Stronger and more stable construction
Like the other PG II vehicles, the PG II 21 and PG II 25 are designed with a very simple, yet strong construction, as the tank is positioned on two 100% through-going profiles. The tank is divided into sections and is also provided with an additional anti-surge partition to improve the stability of the slurry tanker, even when carrying a reduced load. The new models are also equipped with a mechanically adjustable drawbar, which can absorb the forces that propagate to the slurry tankers from the increasing heavier and more powerful tractors that pull them. This helps to ensure a longer lifetime for the slurry tanker by reducing the shock loads in the undercarriage. At the same time, the draw height of the tanker can be adjusted, so you can always ensure optimal coupling between the tractor and the slurry tanker, without having to use adapters.
All three features - the through-going profiles, the extra anti-surge partition and the mechanically adjustable drawbar all contribute to making the new PG II slurry tankers stronger and more stable. They can therefore drive faster, so that delivery capacity is increased.
A hydraulically cushioned adjustable drawbar is available as an additional option. This can be used to ensure that the tank remains in a horizontal position, allowing it to be fully filled. For emptying, the front end can be lowered to provide more gradient and improve the flow to the pump at the front if necessary. There is already a built-in gradient in the bottom frame of the tank on the new PG II slurry tankers.
More flexible undercarriage
The lift of the front axle on the two new slurry takers has been increased by approximately 30%, so there is greater ground clearance under this axle when driving to and from the fields on public roads. This provides a more flexible undercarriage that is better cushioned. It also provides improved driving comfort for the driver.
The maximum turning angle has been increased from 12.5 to 15 degrees. There means there is less risk of damage in the field, since it is minimized at full steering lock.
Pump tower with greater capacity
The two new PG II slurry tankers are equipped with the more compact pump tower from SAMSON AGRO. The reflux pipe and hydraulic hoses are integrated into the pump tower and are better protected against shocks and blows. It is also more flexible than the old pump tower, and can extend vertically down into the slurry tanks right next to the slurry tanker. This means that covered slurry lagoons can be emptied easily through the hole in the tent cover.
It also fills 15% faster than the pump tower on the PG slurry tankers. This is because the cross-sectional area of the filling pipe has been increased. The pump tower’s hydraulics are also optimized in order to increase the capacity of the filling pump.
Wheel-drive tankers have an agitator function on the pump tower, so you can spray the slurry through the pump tower and thereby mix the slurry in the slurry tank before pumping it into the slurry tanker.
"Return to Center"
For the coming season, a new feature is offered on the pump tower on PG II slurry tankers with the SlurryMaster8000 control system. It is called "return to centre" and it helps to manoeuvre the pump tower quickly and safely back in the correct position up in the drip tray on the slurry tanker when the slurry tanker has been filled. The new feature consists of two sensors mounted up on the slurry tanker under the rim on the pump tower. The sensors detect when the pump tower is close to the slurry tanker and they then reduce the speed of movement of the pump tower towards the slurry tanker. When the pump tower has been manoeuvred over the slurry tanker and is hanging directly above the drip tray, this is also detected by the two sensors, which then provide a signal so that the driver knows that he can now simply lower the tower vertically down into the drip tray, so that it is back in place and he can proceed out into the field. This is useful for the drivers, so they can avoid damage to the pump tower.
Large unloading capacity
PG II 21 and PG II 25 are provided with the new unloading pump from the PG II series. Its capacity has been increased by 15-20% compared to the unloading pump on the PG slurry tanker. This is also an indication of the future-proofing of the slurry tanker to allow for wider devices with more slurry to be pumped through them.
There is also easier access to service the unloading pump on the new PG II slurry tanker, as it is bolted to the tank. On the PG series, the unloading pump is welded to the tank.
PG II 25 with HWD
Of the two new PG II slurry tankers, the PG II 25 comes with fully hydraulic wheel drive (HWD). Many Danish contractors prefer to have their slurry tankers delivered with HWD. This provides a very powerful and effective slurry tanker that can handle a more hilly terrain and wetter soil. It can also reverse out of many sticky situations. It also produces reduced wheel-slip on grass during the summer.
By purchasing a PG II 25 HWD, therefore, you obtain the ultimate spreader vehicle, which will be very gentle on the field.
The pump unit on the wheel-drive is provided with a split gearbox with two pumps, which power the two wheel motors, as well as the filling and spreading pump. A wheel-drive vehicle will therefore be filled faster. It is filled at a rate of up to 12 m3/minute.
Position sensor on the lift
The SlurryMaster8000 control system for the PG II slurry tanker means that there is also an option now to purchase a position gauge - or height sensor - for the lift.
The option of the SlurryMaster8000 control system allows the driver to configure 1) the maximum height allowed on the device during transport, 2) the height of the lift while working with the equipment in the field, and 3) the height of the lift when the machine is turned.
The actual height of the lift can also be read off the screen, so the driver can easily see if the lift is in the desired position.
Interesting ejector and SAP solutions
The PG II 21 and PG II 25 are also available with SAMSON AGRO’s new ejector filling pump. The ejector pump technology is widely used and tested in Germany and France. SAMSON AGRO’s ejector filling pump distinguishes itself by being effective, maintenance-free and economical, both to purchase and use. Unlike other vacuum systems on the market, the SAMSON AGRO ejector maintains a high level of performance throughout its life, since there are no wearing parts that can wear out or need to be replaced. It is a so-called "Inline" ejector which is built up on "a line". This minimized flow losses and vacuum formation is optimized. The simplicity and robustness of the system also makes the ejector very handy when very difficult fluids need to be pumped. The pumping technique is well known from other industries.
Along with the new fill arms solutions (SAP 1 Mk2 and SAP 2) that can dock onto slurry transporters, reception tanks with docking funnel, lagoons with docking stations and buffer container with extra hose sections, these are extremely flexible and economic pumping and filling solutions compared to the traditional pump tower that is usually selected in Denmark. However, this type of pumping and filling technology can also be very attractive for Danish users who wish to use it for e.g. sludge suction tasks.
Sales of the PG series have been discontinued
With the introduction of PG II 21 and PG II 25, SAMSON AGRO decided to stop production of the PG slurry tankers.
The PG 25 has been the company's most popular product over time. More than 1,000 PG 25 vehicles have been produced. It has been produced by SAMSON AGRO since December 2000. At the time, SAMSON AGRO was established as a merger of the four companies JOS in Langå, SAK in Løgstør, UM in Brønderslev and Samson in Tange.
The first SAMSON AGRO PG 25 slurry tanker was sold to Poul S. Poulsen in Hurup via Maskinhandler Indkøbsringen (MI) and the agricultural machinery dealer J. Hundahl in Thisted. In February this year, he again became a dealer of SAMSON AGRO machines after a break.
Since their launch in 2013, PG II slurry tankers have quietly taken over the sales of the PG vehicles, overall both abroad and at home. This is only to be expected, as the PG II series is largely developed on the basis of the requirements of SAMSON AGRO’s customers for a future-proofed slurry tanker.
SAMSON AGRO will mark the discontinuation of the PG series with a reception for its employees in August.
