Bakorund In connection with the cultivation of frogs on the fact that different types of driven agricultural implements are used, there is a need to find out where the field is short and where to dig. An example of such a situation is when fertilizer and / or pesticide is to be applied to a previously sown or planted fait.

It is an edge to switch off row units corresponding to tracks for tractor wheels during skiing. When the plant begins to germinate, empty rows are formed. When application and / or pesticides are to be applied, the tractor wheels are placed over these empty rows, whereby the damage to the frog is minimized and you know where in the field you are going to short or short. In order to minimize the area loss associated with this set to form spk, the tractor's tires are usually replaced with much narrower tires for scans, than those used in tillage and sowing.

For some graders, however, it is not necessary to switch off any row unit, but the distance between the damages must be such that the tractor wheels (which can, but must not, be narrower as above) and fk space between adjacent rows.

Since shutting down row units in a narrow situation is not necessary, there is a need for another way of finding out where to drive and where to drive, so that subsequent raids, for example when applying pike and / or pesticides, will be optimal. 8/9/2013 10:40 AM VA_NoOrganisation \ VADERSTAD-VERKEN AMPATENT12013-06 KORT SPARMAR \ SE \ 21064837 \ 20130808_21064637._Applicationtext_OPN.doc 2 Summary One thing is thus to provide alternatives where to call Walla reda kora pa ett fait.

The invention is defined by the appended independent claims.

Embodiments appear from the appended dependent claims, from the following description, and from the drawings.

According to a first aspect, a method of seeding exposed to a frog is effected on a fait by means of a co-machine comprising a plurality of row units, each of which is arranged to dispense a respective row of exposed. The method comprises performing at least two substantially parallel crossings over the field, whereby the usual row unit during the crossing outputs a respective row of the seed. The method further comprises modifying the output of at least one of the row units during a start period of an Overpass and / or during an end period of an Overpass, so that the row of frog formed by the row unit exposed, at a start portion and / or at an end portion thereof, will to differ visually from Other rows of grOda.

By the term "co-machine" is meant not only such machines which are normally referred to as co-machines, but also precision co-machines (so-called "planters") and other types of machines which in some way discharge crops in 20 rows.

In the same way, the term "exposed" means saplings exposed in the form of seeds, mares or root parts, but also exposed in the form of pre-incubated plants and thus comparable forms of exposed.

By "starting portion" is meant a relatively short portion of a row of exposed or frog, which is located at the end of the row where the discharge of the frog in the row takes place first.

By "end portion" is meant a relatively short portion of a row of exposed or frog, which is located at the end of the row where the discharge of the frog in the row takes place last.

By "visually" is meant that the difference should be substantially optically identifiable, even if this is done with the aid of aids, such as filters, sensors and / or irradiation. 2013-08-09 10.40 VA_NoOrganisabon \ VADERSTAD-VERKEN AB \ PA FENT \ 2013-06 SHORT SAVINGS \ SE \ 21084637 \ 20130808_21064637_Applicationtext_OPN.doc 3 By modifying only one party at the start or end of a line, an existing indication is achieved ott to perceive and which meant minimal area loss.

The method is particularly suitable for use in seeding which takes place through a number of substantially parallel crossings, of which every second crossing takes place in a first direction and every other crossing takes place in a second direction, which is substantially opposite to the first.

Furthermore, the method is particularly suitable for use when sowing where the supply of all row units is substantially brought to a halt while watering between two adjacent crossings is carried out. The supply of the row units can thus be brought to a halt when a Crossing ends, after which watering takes place and the feeding of the row units is resumed when the subsequent Crossing is stopped. In this way, essentially no seed is sown on the water table. At least not from the main frog.

The irrigation can be in the order of 180 degrees. Two Crossings can, but must not be completely adjacent to each other.

The modification of the feed can refer to one or more lines. For example, in some crops, a clearer marking can be achieved by closing two adjacent row units after or before watering, ie. during an initial and final phase of a Crossing.

In the process, the start period and / or the end period may be shorter than 5% of the length of the row, preferably shorter than 1% of the length of the row, about 0.3-4 m, 0.5-3 m, about 2 m or about 1 m.

The co-machine may comprise a number of N row units and said modification is effected for every Nth row unit.

The modification may include at least one of the non-feeding of the exposed, sparser feeding of the exposed, tattered discharge of the exposed, and discharge of a second exposed kir another frog.

The method may further comprise performing at least one Overpass Over 30 field without modifying the output from any of the row units during an initial period of an overpass or during an end period of an Overpass. 2013-08-09 10.40 VLNoOrgantsationlVADERSfADNERKEN AB \ PATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064637 \ 20130808_21064637_Applicationtext_OPN.doc which at later crossings shall be overcrowded with a much wider fertilizer spreader or pesticide spreader.

The procedure may further comprise performing alternating Crossings with or without modification of the output, whereby Crossing with modification of the output constitutes every other Crossing, every third Crossing, every fourth Crossing or every fifth Crossing.

Alternatively, or as a complement, the method may comprise performing at least two consecutive and substantially opposite Crossings, the output from different row units being modified at each of said Crossings.

The two consecutive and opposite Crossings can be immediately consecutive, ie. without flag intermediate Crossing.

The line unit whose output is modified can thus vary according to what is necessary to ensure that a center line is provided for the following implement.

Alternatively, or as a complement, the method may comprise carrying out at least two consecutive Crossings and in essentially the same hall directed Crossings, the output from different row units being modified at each of said Crossings.

The two consecutive and that the same hall directed the crossings can be separated by an intermediate crossing at the opposite hall, ie. without flag intermediate Crossing. Alternatively, the crossings may be immediately consecutive, for example when seeding is carried out according to a sample where seeding in different directions takes place at different parts of the field, as when seeding in a circular sample.

The method may further comprise in a control unit receiving position data for the co-machine and in controlling the row unit at least partly based on said position data. 2013-08-09 10.40 V: \ NoOrganisation \ VADERSTAD-VERKEN AB \ PATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064637 \ 2013080821064637_Applicationtext_OPN.doc In the procedure, a distance between adjacent rows of crops can be such that an agricultural implement can and one of its wheels placed between the adjacent rows of tv5.

According to a second aspect, a method of discharging material by means of a discharging machine is provided in a field on which the frog grows in substantially parallel rows. The method comprises visually identifying a row of said frog, which has a starting portion and / or an end portion, which differs visually from Other rows of frog, and in front of a run substantially parallel to said rows, guiding the dispensing machine, seen perpendicular to the rows , based on p5 named start part or end part.

The term "material" means sAval liquid as granular or powdered material. This can all55 include both fertilizers and pesticides.

The term "dispensing machine" includes as many dedicated dispensing machines as towed dispensing tools.

By controlling based on p5 visually identified start portions and / or end portions, rows 5 have been created an easy way to find out where to Wirt and where to run.

In the process, the machine can be controlled so that a benchmark has the output machine aligned with a row having said start portion or end portion.

A "benchmark" can be a specially arranged part of the machine, e.g. a "sight", but can also be an arbitrary part, as a center line has the machine.

The method may further comprise in a control unit receiving position data for the machine and in controlling the output machine 5 at least partly based on said position data.

Brief Description of the Drawings Fig. 1 is a schematic sketch of a sample for placing rows of exposed p5 a fait. 2013-08-09 10.40 VLNoOrganisation \ VADERSTAD-VERKEN AB \ PATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064637120130808_21084637._Applicationtext_OPNAoc 6 Fig 2 is a schematic sketch of a pattern for driving with a machine on a grid.

Figures 3a-3b schematically show alternative patterns for placing rows of exposed and corning with the following machine on a fait with grOda.

DESCRIPTION OF EMBODIMENTS In the following, the invention will be exemplified by reference to agricultural implements in the form of a precision co-machine 1 and a pesticide spreader 4, which are pulled by a tractor 2. The precision co-machine 1 has a plurality of row units 11a-11h, each of which discharges a respective row. of exposed.

Fig. 1 schematically shows a number of ready-made rows 31a-31h and a number of rows 32a-32h, for which skis p5g5r. The finished rows 31a-31h have been set while the agricultural implement 1 is being mapped in a first direction S1 and the seed paging in Fig. 1 is now tangent to a second direction S2, which is substantially parallel but opposite the first direction S1. A row spacing R is present between rows 31a-31h, 32a-32h.

Among the finished rows 31a-31h there is a modified row 31d, the supply of which has been started and interrupted a distance M1 later and earlier, respectively, earlier than the supply to Other rows 31a-31c, 31e-31h.

Among the rows 32a-32h of which skis p5g5r there is a modified row 32f, the feed of which is started a distance M2 later than the feed to Other rows 32a-32e, 32g-32h.

The sections M1, M2 may, for example, be shorter than 5% of the length of the row, preferably shorter than 1% of the length of the row, about 0.3-4 m, 0.5-3 m, about 2 m or about 1 m. , M2 can, but must not, be the same length.

The distance M1 is achieved by modifying the output from a row unit 11d. The distance M2 is achieved by modifying the output from another row unit 11f.

It will be appreciated that a row may have modified start portion (Figs. 3a, 3b), modified end portion (Figs. 3a, 3b) or both modified start portion and modified end portion (Figs. 1-2), as appropriate. 2013-08-09 10.40 VLNoOrganisation \ VADERSTAD-VERKEN ABTATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064637 \ 20130808_21064637_Applicationtext_OPKdoc 7 Which of the row units' 11a-11h output is modified depends on, for example, the distance between rows and 11 -11h at the agricultural implement 1 and the width has subsequent implement 4.

Figures 3a and 3b show schematically how the output from row units having a 6-row co-machine 1 can be modified to fit with a twelve-row following tool 4.

Sam appears from Fig. 3a, at a first Crossing Si, row unit number 7 is closed off at the beginning of the crossing, so that the seventh row from the left, gets a modified starting section. At a second Crossing S2, no row unit ay is closed. At a third Crossing 03, row unit number 3 is barred off at the end of the Crossing, so that the 19th row from the left gets a modified end section. At a fourth Crossing S4, row unit number 7 is stitched off at the end of the Crossing, so that the 31st row from the left gets a modified end section.

As shown in Fig. 3b, the towing vehicle 2 and the following implement 4, at a first overpass F1, are steered in with the seventh row from the left as a guideline.

After watering, the towing vehicle 2 and the following implement are steered, at a second Overpass F2, in with the 19th row from the left as a guideline.

If a distance, seen perpendicular to the feed directions S1, S2, between modified row ends is desired, which is greater than the width of the agricultural implement 1, it is possible to run crossings with alternating modified rowing and without modified rowing, respectively. For example, every other, every third, every fourth or every fifth crossing can take place with a modified line, whereby other crossings take place without a modified line.

Furthermore, it is possible to only run Crossings with modified erasure at the start of escape Overfart or only with modified erasure at the end of habit Crossing.

Furthermore, it will be appreciated that the output of the row unit or units being modified may vary, for example as shown in Figs. 3a and 3b. This is especially true when the co-machine is in the form of a precision co-machine, which operates with relatively large row spacings, for example in the order of 70 cm, which with an 8-row precision co-machine gives a working width of 560 cm. This 2013-08-09 10.40 VLNoOrganisation \ VADERSTAD-VERKEN AB \ PATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064837 \ 20130808_21064637_Applicationtext_OPN.doc 8 co-machine width can be combined with a barbed spreader or a pesticide spreader 10 in m .

It will be appreciated that with large line spacing it will not always be possible to fit modified radar edges so that perfectly non-overlapping subsequent crossings can be marked. It may therefore be necessary to choose which radar output is to be modified so that the modification takes place as close as possible to a desired center layer.

It is possible to effect the modification in a number of different ways: As mentioned above, it is possible to completely switch off the output of exposed to the straight M1, M2 (or equivalent time) of modified output as desired.

Alternatively, the output can be made more sparse or tattered.

As a further alternative, discharge can be provided by an alternative frog.

The modification of the output can be accomplished in a number of different ways.

One possibility is to direct the user himself to modify the output for one or more line units before the started crossing. In the same way, it is possible to let the user himself modify the output for one or more row units before the last part of a Crossing.

In such cases, the user can himself control one or more of the row units to modify the output, for example by switching the feed off or on, alternatively the Second feed speed.

Alternatively, the control system of the dispensing machine can be designed and / or programmed so that when a signal is made that a new crossing is to be started, one or more of the line units' output is modified. In the same way, when the signal is about to end Crossing, one or more of the line units' output can be modified.

The signal that the crossing is to be started or terminated can be provided by the user. Alternatively, the signal may be provided based on a control system which determines where or when the signal is to be provided based on knowledge of the position of the dispensing machine. The position can, for example, be determined with the help of GPS or another positioning system, by clOd 2013-08-09 10.40 VLNoOrganisation \ VADERSTAD-VERKEN ABTATENT \ 2013-06 SHORT SAVINGS \ SE \ 21064637 \ 20130808_21064637_Applicationtext_OPN.doc 9 shaving time, based on speed, based on speed , direction, etc.) or with the help of a local signaling system installed at the field.

The raday position R can be determined according to what is considered appropriate for the crop to be sown, the conditions at the place where sowing is to take place and also with regard to the equipment to be used for crossings after sowing.

The raday stand can also be selected to fit a subsequent trouser or harvester.

Such row spacing R may be in the order of 20-100 cm, preferably 30-95 cm, 35-90 cm, 35-80 cm, 45-80 cm or 45-75 cm.

According to specific embodiments, the row spacing may be about 35 cm, about 37.5 cm, about 40 cm, about 45 cm, about 50 cm, about 55 cm, about 60 cm, about 70 cm, about 75 cm, about 80 cm, about 85 cm. cm or about 90 cm. By "approximately" is meant deviations of in the order of +/- 3 cm.

Fig. 2 schematically shows the conveyance of a second agricultural implement 4 over a fact on which rows 31a-31h, 32a-32h with frog have been placed.

Sam appears from the left-hand part of Fig. 2 Ors agricultural implement 4 said that a center line, seen in the direction of travel F1, has the tractor 2 coinciding with a row of modified duck portion 31d.

In connection with watering and steering towards the next Overfart which is to take place in direction F2, the center line of the tractor is lined with a row 32f that has modified duck section. The identification is suitably done visually by the user seeing which row has modified the duck portion and steer towards it.

In addition, the guide can be assisted with the aid of any of the above position determination systems, the visual guide discussed above constituting a complement.

It will be appreciated that the tractor 2 may be provided with a benchmark or "sight" to facilitate steering. Alternatively, what is perceived by the user as the center line of the tractor can be used. 2013-08-09 10.40 VA_NoOrganisation \ VADERSTAD-VERKEN AB \ PATENT \ 2013-06 KORT SPARMAR \ SE \ 21064637 \ 20130808_21064637_Applicationtext_OPN.doc
