Gooseneck Double Twin Shift

No other slurry tanker with a similar capacity is as soil-friendly as a KAWECO DOUBLE TWIN Shift. If paired with the efficiency of a CLAAS XERION and the agility of a gooseneck tanker you will have the perfect self-propelled machine. With a volume of 21,000 liters, KAWECO manufactures the largest single-axle tanker available on the market. Thanks to the undercarriage the soil pressure can be kept very low, despite the large volume of the tanker. KAWECO is the inventor of the DOUBLE TWIN SHIFT undercarriage which has 4 large tractor wheels in 1 single row. This gives the tanker the maneuverability of a single-axle slurry tanker, while it has the load capacity of a tandem axle tanker. This unique undercarriage means that injection requires a significantly lower soil pressure than a self-propelled machine. This means you can start your work sooner, and continue for longer, even in bad weather. Another major benefit is that your tractor can also be used for other work, as opposed to a self-propelled machine, which is not operational at least 6 months a year. KAWECO DOUBLE TWIN SHIFT, many wheels make light work!

The Double Twin shift undercarriage

The KAWECO Double Twin shift undercarriage has four large wheels in a single row. The wheels on the outside can be shifted outwards. This creates an even track of tanker and tractor wheels without having to go over the same track multiple times. Thanks to this unique system, the soil life suffers minimum damage, and the drainage of the soil is left intact. This results in fewer puddles in the field, no tracks, being able to start injecting sooner etc. The stable, extendible chassis profiles are equipped with synthetic strips, which makes the system very maintenance-friendly. The wheels have hydraulic suspension, which provide a well-balanced distribution of the weight over the 4 wheels. On the road, the hydraulic suspension provides comfortable and stable driving properties. All wheels are Air-braked for maximum safety.

Pump and slurry piping

As in every KAWECO tanker the pump is the central part of the machine. The pump is hydraulically driven by means of the power hydraulics of the Xerion, which in turn are operated by the KAWECO computer. During filling this means that the power hydraulics are swiveled out to a maximum meaning that filling can take place at a minimum engine rpm. To increase the pump capacity, it is advised to install a maxifiller in the filling arm or front unit. This will not just increase the pump capacity, but also ensure less wear, thanks to a reduction of the negative pressure in the suction pipe. During the spreading of the slurry, the dosage is automatically adjusted to the driving speed thanks to the hydraulic adjustment of the pump speed. Thanks to 3-way valve at the back of the tanker, the slurry can circulated in the tanker when turning on the headland. This creates a faster availability of the slurry, and a better distribution during the first few meters of spreading.


To keep up the capacity of a pump, stones, feed residue and other contamination must be prevented from damaging the pump. KAWECO offers a Stonecatcher with sufficient volume to slow down the slurry flow for every pump type. This allows heavier objects to sink down to the bottom of the chamber. As an option, the Stonecatcher can be opened from the cabin, as a result of which these heavier objects can easily be removed. Feed residue will be shredded so that they cannot cause clogging. The cutting system uses a preloaded rotor with round mounted blades, that run across a hardox steel plate.

Filling arms

With various types of side and swivel arms and a complete  Front-unit, KAWECO offers the perfect solution for every customer. Thanks to the standard 9,000 l/min pump, the filling arms always are at least 10″ in size. The standard filling arm offers the possibility to suck up slurry straight from deep manure pits. Optionally it can be fitted with a docking ball, which makes it easy to dock onto a nursetank. The TELE-arm can be hydraulically extended for 1.5 meters and it can swivel up to 170⁰. This means that docking onto a truck is made really easy. The KAWECO front unit has been especially developed for filling with a very high capacity, up to 12,000 l/min, and is installed in the front lift or is permanently installed in front of the XERION. This gives a perfect view on the slurry arm. A 10” maxi-filler and a 10” stone catcher with integrated cutter are standard equipment of the front unit. The complete suction piping is 10”.

KAWECO DOUBLE TWIN SHIFT gooseneck options

Every KAWECO tank is standard equipped with a high-quality treatment. The inside is fitted with a two-component EPOXY resin. The outside is scoped and sprayed with two-component polyurethane lacquer. The standard color is KAWECO white with orange.
Two RAL colors are available as an option.

This treatment is many times more durable than a zinc layer and will retain its color even after years.


Filling opening with hydraulic slide on manhole (600 mm). With this filling opening one can easily fill the tank with an external pump. The hatch is equipped with a bearing work to ensure a good sealing.

A hydraulically operated valve is available for easy emptying of the 10″cutting cleaner.

with piping and air vent.

To be able to empty the tank easily with an external pump, a direct connection is recommended.

This hose holder prevents bending of the 6″ hose that goes to the injector.

For the transfer of slurry or the emptying of a silo, the PTW tank can be equipped with an extra three-way valve.

• Filing arm right side
• First pivot point controlled by a hydraulic cylinder
• Second pivot point controlled by a hydraulic spindle motor
• Std. With valve between filling arm and stonecatcher
• Only in combination with 9.000 l/min pump


The andock ball is recommended in conjunction with the PRO suction arm for docking on to nursetanks. This ball replaces the standard 10″ hose (only with PRO suction arm).

• Telescopic docking arm 10″, 1.400mm extendable
• One pivot operated with two hydraulic cylinders
• Std. With maxifiller
• Std. With 8″ knive valve


• Side wivel filling arm 8″ right side
• First pivot point controlled by a hydraulic spindle motor
• Second pivot point controlled by a hydraulic cylinder
• Drip tray


With the KAWECO FRONT-UNIT it is easy to dock to a nursetank. With the arm in front of the cabin you have perfect visibility. Also, the applicatorboom can always be folded out because you don’t have to stand sideways along the nursetank.


•  Required hydraulic volume: 55 l/min

The maxi filler is recommended for thicker slurry or when the slurry has to be sucked out of a deeper cellar. The maxi filler also relieves the slurry pump, making it less vulnerable to wear and tear. In addition, the KAWECO maxi filler guarantees a faster loading process.


• The Guillotine valve will be mounted instead of the standard valve between the fillingarm and the stonecatcher.

This guillotine valve ensures that the filling-arm leaks less.


A tire inflation system allows you to let pressure out of the tires when used in the field. The compressor is driven by the Load-Sensing system. Due to the large amount of oil that is required, it is often not possible to applicate and inflate at the same time.

The KAWECO PRO joystick enables proportional control of a suction arm. (incl. proportional hydraulic valves).
