The Locasem LS3000 Pro, Agrisem's high-capacity solid fertiliser placement machine

Agrisem International is launching a solid fertiliser placement machine with in-soil placement and an associated hoeing system.
The Locasem has a 3000-litre hopper and is available in 4 widths: 9, 10, 11 and 12 rows (with row spacings of 75cm or 80 cm).

According to the manufacturer, based in the Vendée, this product was designed for intensive use at high speeds.

The stainless steel distribution system with decompression chambers and transport through pipes with a diameter of 70mm would make it possible to ?reach record working speeds?.

It is intended for contractors, CUMAs and large farms.

High working speed

Agrisem's Locasem has 5 distributors in 9 or 10 rows and 6 distributors in the 11 or 12-row configuration. The distributors are made entirely of stainless steel with a fluted-roller distribution system.

Each distribution unit has 2 venturis, which then transfer the fertiliser to the placement units through very large-diameter pipes (70mm in diameter).

For an application rate of 600 kg/ha, the maximum working speed with ammonium nitrate NFU42001 is 16 km/h with 9 rows and 15 km/h with 12 rows.

Consistent flow rate between rows

The fluted-roller distribution system is said to ensure perfectly uniform distribution between rows. The variability averages plus or minus 1% depending on the type of fertiliser.

Decompression chamber

Each placement unit has a decompression chamber. Its purpose is to separate the fertiliser from the air flow. This would prevent pressure build-up in the circuit and would therefore allow a much higher hourly output.

These decompression chambers are made entirely of stainless steel.

Mechanical or electronic DPA

The distribution drive is proportional to forward speed. Two systems are available: the mechanical DPA controls the flow rate using a system of interchangeable sprockets.

The electronic DPA controls the speed of the distributors using one or two electric motors. An electronic control box in the cab makes it possible to monitor the operation of the machine and adjust the flow rate settings.

It is then possible to vary the application rates and, as an option, to print work records with an associated printer. The electronic model also makes it possible to shut off half of the drill in order to finish fields while avoiding excessive overlaps.

Large capacity and low loading height

The hopper has a capacity of 3000 litres. The machine's centre of gravity has been positioned very close to the tractor's hitch hooks so that it can be used with medium-power tractors.

Despite its large capacity, the loading height is limited to approximately 2m. The sloping shape of the hopper is said to provide very good visibility during work.

Finally, it should be noted that the machine has a walkway with guardrails 3m wide. It allows optimised loading to be carried out safely.

Ground following

The machine's frame in its 12-row version is 9m60 wide. It is therefore necessary to provide articulations to follow the unevenness of the ground and ensure placement at a constant depth.

The folding extensions are mounted on pivots and the constant pressure of the end units is ensured by two large shock absorbers.

Row following

The end units have a variable spacing that can be adjusted hydraulically from the driver's seat. This function makes it possible to correct the spacings to ensure central placement of the fertiliser in the inter-row.

In its 12-row version, the machine may operate in a field sown with a 4-row drill.

Depending on the quality of the sowing joins, it is then necessary to change the position of the end placement units.

For transport, the end units can also be retracted as far as possible to limit the overhang.

Carbide protection and choice of levelling tools

The placement unit has full carbide protection on the tip and the leg. A removable wing is said to create a scalping effect when the hoeing function is to be combined. Behind the placement unit, either two cultivator-type tines or two discs can be fitted.

Each placement unit has a 3D non-stop safety system, so it can work in difficult soils and in the presence of stones.

Locasem LS2500, a version that can be fitted to existing frames

Alongside this integrated machine, Agrisem International also offers a

technical solution for customers who wish to keep their old anhydrous ammonia placement frames. The manufacturer offers a 2500-litre hopper to be fitted to existing frames. This LS2500 module can have a mechanical or electronic DPA like the Locasem LS3000 .
