Arable injectors

Arable injectors
An appropriate structure

Arable injectors make it possible to inject slurry deeply. They also loosen the ground.
They are fastened on a galvanized double-beam frame reinforced by radiant crosspieces. The main advantage of this assembly is to focus the strains of the implement on the tanker, which then transfers them to the tractor. The stress is therefore reduced and the tank is not subjected to distortion.
The basic frame is modular for all models: large width models are manufactured on the basis of the 2.80 m models with extensions.
The frame of the injectors wider than 3 m are fitted with a double-acting hydraulic folding system with anti-twisting safety stop. All these implements are fitted with a road lighting system.

The frame carrying the injectors wider than 3 meters are fitted with a double-acting hydraulic folding system with anti-twisting safety stop. All the models are equipped with a road lighting system.

In order not to exceed the maximum transport width and not to strike against obstacles, the Terraflex/2 (5200/13 SHK & 5100/17 SHK) and Terraflex/3 injectors are fitted with retractable outer tines.

The gauge wheels allow to adjust the working depth of the tines.

The injectors are standard equipped with 2 gauge wheels 200/60-14.5 (Ø 605 x 210 mm) and can be completed by 2 other wheels available in option on the large widths from 5m10.

In case of thicker slurry (cattle slurry,...) or higher doses per hectare, it is advisable to choose Ø 60 mm macerator outlets and pipes instead of Ø 48 mm ones (standard).


General points

The Terrasoc arable injector is fitted with rigid tines ended by flat duckfoot shares (24 cm wide) with a 40 cm spacing between them and a shear-bolt security. The shape of the tines and the wide serration of the shares prevent any clogging risks.
The advantages of this system are:
• an efficient soil ploughing;
• an injection depth ranging from 10 to 12 cm;
• an outstanding stubble ploughing (the share best suited to mechanical weeding);
• a smaller required tractor power.


The slurry, flowing through a hose having the same shape as the tine, is laid down under the foot of the share making a groove in the ground. With the Terrasoc, slurry is injected on a large width (from 15 to 25 cm depending on the type of slurry and ground), which allows a high spacing between the tines, as well as a small tractor power.
- the gauge wheels ensure a centralized adjustment of the working depth;
- the tines are fitted with an individual 3-position adjustment of the depth by tightening or loosening the bolts at their fixing points on the frame;
- the same principle allows to modify the sloping angle of the tines to loosen the ground more or less aggressively.

Stubble plough

The injector is fitted with a support that can be hitched to the standardized 3-point linkage of a tractor. In this way, it can be used as a simple stubble plough or with an umbilical system.

General points

The Terraflex models are fitted with flexible tines fixed on wide spring leaves (Everstrong type) ended by a 6.5 cm wide reversible straight share.
These tines ensure:
• an improved ground loosening thanks to the vibrating effect;
• a good vegetable residue mixing;
• a perfectly torn plough soil and a better prepared seed bed;
• a working depth ranging from 12 to 15 cm.


The share makes a groove in the ground and the slurry is then laid down by the injection hose that is just behind the share. As they are vibrating, these tines are more resistant to obstacles (stones, etc.) but offer a less regular working depth.
The working depth is adjusted by a central adjusting device on the gauge wheels.
Like the Terrasoc, the Terraflex injector can be used as a stubble plough or with an umbilical system.


In order to choose the best compromise between flow rate, distribution and organic matter flow, the row spacing on the Terraflex/2 is 30 or 40 cm, depending on the model.


As an option, Terraflex/2 injectors can be fitted with a levelling harrow.

Terraflex/2 XXL

The TERRAFLEX/2 XXL offers the possibility to work on larger widths from 6 to 7.60 m. Furthermore, the tine spacing is unique (40 cm).

The row spacing of the Terraflex/3 is 30 or 40 cm. The tines are distributed on 3 rows, which leaves a bigger space between them. JOSKIN designed this injector to avoid blockages. It is thus particularly interesting when the vegetation is abundant. The spacing between the 1st and 2nd row is moreover larger than between the 2nd and 3rd row.

Tines with 11 cm reversible and reinforced blue share (type Kongskilde Vibroflex) can replace the standard models. They are designed to bury and mix larger quantities of straw and vegetable residues.
Their specifications are:
• two folds allowing to make the earth go up and the vegetable matter down;
• a vertical area (above the share) to mix the plants and the ground in an optimal way;
• a 11 cm width;
• a further improved sturdiness;
• a certain reversibility;
• a design for mulch seeding;
• a very good mechanical seeding effect (roots and seeds).


As an option, Terraflex/3 injectors can be fitted with a levelling harrow.

General points

The discs with a diameter of 510 mm of the TERRADISC are each mounted on a shock absorbing element, which is bolted to the frame.
This implement ensures:
• an efficient incorporation of slurry;
• a working adjustable depth up to 18cm;
• a perfect stubble ploughing work.


The first row will open the ground. Slurry will then flow through the injection pipes and be laid down in these openings.

The second row of discs, which is positioned in the opposite direction as the first one, will cover up the slurry.

This arable injector allows :
• high speed working ;
• a working depth up to 18 cm ;
• an efficient incorporation of slurry in the ground for a homogeneous mix with the soil ;
• quality cultivation;
• almost zero losses of fertilizing elements.


Two powerful double-acting hydraulic rams fold both parts of the injector upwards in order to get a transport width of 2.90 m.
The machine is in this way compact during transport while keeping a light overhang.
