Chop­star-HybridEin­böckThe Chop­star-Hybrid has been deve­lo­ped for hoeing weeds in mulch stands. Flat discs sit on the hoeing bodies, which can rota­te free­ly. The pla­tes cut the roots of the weeds just below the soil’s sur­face. The flan­ged wheels cut the soil and mulch lay­er and pre­vent a blo­cka­ge of the pla­tes. The machi­ne can also be com­bi­ned with auto­ma­ted came­ra steering.Root crops,

Chop­star Twin Hackgerät
Ein­böckThe Chop­star-Twin har­row was deve­lo­ped for exact hoeing on top of rows. The hoeing par­al­le­lo­gram does not work clas­si­cal­ly bet­ween the rows, it is arran­ged direct­ly abo­ve the row pro­du­cing a very nar­row hoeing belt. The ang­le-adjus­ta­ble hol­low discs in com­bi­na­ti­on with pro­tra­c­tors offer the pos­si­bi­li­ty of hoeing young plants very ear­ly and very tight­ly. Two farm flex wheels sup­port an exact working depth of the hoeing elements. Root crops,

Rota­pullTech­ni­sche Uni­ver­si­tät DresdenThe Rota­pull princip­le was deve­lo­ped for fle­xi­ble soil cul­ti­va­ti­on, which adap­ts to dif­fe­rent soil or vege­ta­ti­on con­di­ti­ons. Rota­pull com­bi­nes wrought coul­ter tools with a rotor. Its deve­lo­pers have crea­ted a new ope­ra­ting princip­le com­bi­ning a simp­le con­struc­tion with high power and fle­xi­ble adap­t­ati­on to dif­fe­rent con­di­ti­ons. The results is a deeper soil loo­se­ning with mana­ge­ab­le seed­bed cultivation.Soil til­la­ge; stubble tillage
Plug-Mulch-Ver­fah­ren (Plough- mulch- method)Tech­ni­sche Uni­ver­si­tät DresdenThe machi­ne com­bi­nes the agri­cul­tu­ral advan­ta­ges of ploughing with the advan­ta­ges of mulch see­ding. The two steps are united into one ope­ra­ti­on (front mul­cher – trac­tor – plough com­bi­na­ti­on). The grown green manu­re plants or har­vest resi­du­es are app­lied direct­ly to the ploughed area during ploughing. The spe­cial front-moun­ted throw-dis­tri­bu­ti­on mul­cher remo­ves the orga­nic mate­ri­al from the front area of the trac­tor befo­re pas­sing over and dis­tri­bu­ting it on the adja­cent ploughed area. Ploughing and mul­ching combination
Leib­ing-Hacke (Har­row)Die­ter Leib­ing Maschi­nen­bau & BiohofIn con­trast to con­ven­tio­nal hoeing machi­nes, the Leib­ing-Har­row, which is atta­ched to the front, has only one hin­ge per coul­ter; depth con­trol is pro­vi­ded through a skid. The hoeing coul­ters can be adjus­ted regar­ding working depth and ang­le using the hole-grid. Tele­scopic gas springs con­trol the pres­su­re to the soil. The hydrau­lic ver­si­on with adjus­ta­ble coul­ter pres­su­re, indi­vi­du­al coul­ters or or coul­ter parts can be lifted.Uni­ver­sal hoeing machi­ne for row crops

The SV-15M, Vier­mann offers an effec­ti­ve and easy-to-hand­le tech­ni­que for instal­ling hoses. The SV-15M demons­tra­tes its bene­fits par­ti­cu­lar­ly when used for sen­si­ti­ve cul­ti­vars or in small-sca­le agri­cul­tu­ral units.Irri­ga­ti­on of vege­ta­ble are­as; lawns
Unkrautro­bo­er (Weed robot)
Pool / CarréThis agri­cul­tu­ral robot main­tains the cul­ti­va­ted are­as auto­ma­ti­cal­ly. It does not only remo­ve weeds – it also records various para­me­ters such as weed pres­su­re, den­si­ty, degree of ripeness and mois­tu­re. The­se values can help to make crop manage­ment decisi­ons. The robot, powe­red through an electric motor, moves with a sys­tem that inclu­des GPS gui­d­ance, came­ras and lasers. The far­mer can moni­tor the weed robot via smart­pho­ne or tablet.Vege­ta­ble and spe­cial crops
Groß­ro­bo­ter (Lar­ge-sca­le robot) DinoKULT / Naio TechnologiesNaio Tech­no­lo­gies is cur­r­ent­ly working on a weed robot for lar­ge vege­ta­ble cul­ti­va­tions. The lar­ge robot is equip­ped with GPS and came­ra con­trol and can thus be sca­led to the crop/row spa­cing. Its working width for the beds ran­ges from 1.50 m to 1.80 m. The tools like hoe and har­row are fle­xi­b­ly exch­an­ge­ab­le and can thus be adap­ted to the crops. The aim is to also pre­pa­re the weed­ing robot for other tasks such as sowing and fer­ti­li­sing. It is cur­r­ent­ly still in the pro­to­ty­pe stage.Vege­ta­ble and spe­cial crops
Track Roll­spur­lo­cke­rer (Loo­se­ner)Uni­ver­si­tät HalleThe Track Loo­se­ner was deve­lo­ped to avoid water ero­si­on in root crops as much as pos­si­ble. It is an add-on for hoeing machi­nes. The tines cut like dig­ging forks about 25 cm deep into the soil. This loo­sens and enlar­ges the soil sur­face again, so that rain­wa­ter drains off more slow­ly. The Track Loo­se­ner has been tes­ted in the field and its poten­ti­al for redu­cing ero­si­on has been confirmed.Row hoeing machine
Grim­me TerraProtect GRIMME Land­ma­schi­nen­fa­brik
The Grim­me Ter­ra­Pro­tect crea­tes trans­ver­se embank­ments bet­ween the pota­to rid­ges, which redu­ce the risk of ero­si­on and at the same time pro­mo­te water infil­tra­ti­on. Tines at the very front of the machi­ne loo­sen the soil which also incre­a­ses the water infil­tra­ti­on. Ano­t­her fea­ture is the intel­li­gent con­trol sys­tem for the trans­ver­se embank­ments depen­ding on the pace and tram­li­ning control. Trans­ver­se embank­ments for ridge cultivation 
Mulch-Pflanz-Maschi­ne (Mul­ching-Plan­ting-Machi­ne)Live2giveThe recent­ly deve­lo­ped Mulch­T­ec plan­ting tech­no­lo­gy makes it pos­si­ble to plant young vege­ta­ble plants mecha­ni­cal­ly into a clo­sed mulch cover. The mulch lay­er is cut by a cut­ting device, after­wards the plant is pla­ced into the hole and the mulch cover is clo­sed again by pres­su­re rol­lers. An inte­gra­ted under­floor fer­ti­li­sing device ensu­res suf­fi­ci­ent nut­ri­ent sup­ply from the begin­ning, even during the time in which the mulch lay­er its­elf does not pro­vi­de nut­ri­ents yet.Plan­ting vege­ta­ble into mulch cover
Sen­so­ren­sys­tem Bie­nen­ge­sund­heit (Bee health sen­sor system) Uni­ver­si­tät KasselThe moni­to­ring sys­tem has been deve­lo­ped to sup­port the manage­ment of bee health and pro­duc­ti­vi­ty. The sys­tem con­sists of several moni­to­ring units for data collec­tion and a con­trol unit for mobi­le power sup­ply. Each moni­to­ring unit con­sists of a mini­com­pu­ter and several sen­sors that record para­me­ters con­cer­ning the colo­ny and the envi­ron­ment at spe­ci­fic time inter­vals (e.g. weight of the colo­ny, tem­pe­ra­tu­re and humi­di­ty in the apia­ry and out­side, noi­se). The data is trans­fer­red to a ser­ver whe­re it is ana­ly­sed and the infor­ma­ti­on is later sent to the bee­kee­per via smartphone.Bee­kee­ping, bee management

Mul­ti­Tool­Trac Type ENSMul­ti­Tool­Trac BVThe Mul­ti­Tool­Trac is a trac­tor with electric dri­ve, deve­lo­ped by far­mers in the Nether­lands. Fea­tures inclu­de varia­ble track width adjus­t­ment, lon­ger wheel­ba­se, three moun­ting posi­ti­ons (front, cent­re and rear), all-wheel stee­ring and all-wheel dri­ve. In the cent­re axle area, the dri­ver has a very good view on the field. The varia­ble track width adjus­t­ment (road: 2.25m; field: 3.20m) takes only a sin­gle bot­tom push and makes a bed cul­ti­va­ti­on sys­tem with fixed dri­ving lanes possible.Ara­ble far­ming, vege­ta­ble gro­wing, spe­cial crops
Jäte- und Ern­te­flie­ger (Solar Weeder)WetechThe Solar Weeder is an auto­ma­ted working machi­ne powe­red by a pho­to­vol­taic sys­tem. It is sui­ta­ble for weed­ing and har­ve­s­ting dif­fe­rent vege­ta­ble crops. High-per­for­mance accu­mu­la­tors store the ener­gy from the pho­to­vol­taic modu­les and simul­ta­ne­ous­ly pro­vi­de ener­gy for the engi­ne to operate. Vege­ta­ble gro­wing, spe­cial crops
1160 eHof­tracWei­de­mannThe 1160 eHof­trac com­bi­nes the fami­li­ar fea­tures of the Hof­trac with an emis­si­on-free and quiet electric engi­ne. Fea­tures are: com­pact and robust con­struc­tion, low cent­re of gra­vi­ty, small tur­ning radi­us, power­ful out­put and a lar­ge num­ber of dif­fe­rent attach­ment tools. A lead-acid bat­te­ry powers two sepa­ra­te electric motors: one for the dri­ve and one for the hydrau­lic sys­tem, which mini­mi­zes ener­gy con­sump­ti­on. The bat­te­ry power is suf­fi­ci­ent for about 3 to 4 working hours, the char­ging pro­cess takes 6 hours.Farm and sta­ble work
SILOKING Truck­Li­ne 4.0 Com­pact 8Silo­kingThis is the first machi­ne in its size class powe­red 100 % electri­cal­ly and self-pro­pel­led, a feed mixer with exter­nal loading. The con­tai­ner volu­me is 8 m³. The machi­ne is used for the mixing, trans­por­ting and dosing of fod­der. One bat­te­ry char­ge is suf­fi­ci­ent for three fee­ding mix­tures for up to 100 dai­ry cows plus off­spring. An optio­nal hea­vy-duty bat­te­ry allows up to 5 mixing cycles per day. The cou­pling to the inter­nal farm manage­ment makes the con­nec­tion of rene­wa­ble ener­gies par­ti­cu­lar­ly efficient.Ani­mal Hus­bandry; Ani­mal Feeding
