Sämaschi­nen-Inno­va­tion

The inno­va­tions in seed drills lie in the detail. With new think­ing and on the basis of our expe­ri­ence with rub­ber and plas­tics, the JÄGER Group devel­ops prod­ucts and assem­blies for mod­ern agri­cul­ture and thus deci­sive­ly facil­i­tates the every­day life of farm­ers. In the fur­ther devel­op­ment of seed drills, it is impor­tant to per­fect the sow­ing and cul­ti­va­tion of the grain. Too much sow­ing at one point is just as unde­sir­able as too much free space.

Exchange­able inserts match­ing the seed

The JÄGER Group has devel­oped improved inter­change­able rub­ber inserts for the auto­mat­ic dos­ing unit. In the unit, the seeds are cor­rect­ly dosed via rotors. The indi­vid­ual rotors have the same inter­nal struc­ture, via which the con­nec­tion to the dri­ve shaft is made. On the out­side they are adapt­ed to the respec­tive seed in size and shape, which makes it easy to change the inserts. Con­trac­tors and farm­ers need this quick exchange on site so that the machines can be retro­fit­ted for dif­fer­ent pur­pos­es and ser­vice life is kept low.

Indi­vid­ual devel­op­ment for dos­ing discs: Envi­ron­men­tal con­di­tions require spe­cial rub­ber com­pounds

Togeth­er with the seed drill man­u­fac­tur­ers, we devel­op the meter­ing wheels in such a way that they meet the respec­tive chem­i­cal and cli­mat­ic require­ments. Sow­ing at ten degrees out­side tem­per­a­ture may require a dif­fer­ent rub­ber com­pound than sow­ing in a hot envi­ron­ment. The rub­ber can be adapt­ed by select­ing the com­pound. Here we can draw on our wealth of knowl­edge from prod­uct devel­op­ment with rub­ber and plas­tic. The JÄGER Group has sophis­ti­cat­ed test meth­ods and test pro­ce­dures at its dis­pos­al to deter­mine the right rub­ber com­pound for the appli­ca­tion.

The seed is usu­al­ly sup­plied with a suit­able fer­til­iz­er addi­tion, the fer­til­iz­ing of the sow­ing is thus com­plet­ed. When select­ing the mate­r­i­al, we pay par­tic­u­lar atten­tion to ensur­ing that the chem­i­cal­ly aggres­sive fer­tilis­er used is neu­tral in rela­tion to the poly­mer mix­ture used in the rotors. Fur­ther impor­tant cri­te­ria of our cus­tomers are the abra­sion resis­tance of the mix­ture as well as dura­bil­i­ty in agri­cul­tur­al use. Here you ben­e­fit from our many years of expe­ri­ence in com­pound devel­op­ment and opti­mi­sa­tion!

Slack tyre as pres­sure roller in endurance run

To pre­vent the seed from lying open in the fur­rows, seed drills use flop­py tyres as pres­sure rollers. The num­ber of flop­py tyres depends on the num­ber of rows sown. The JÄGER Group man­u­fac­tures assem­blies which con­sist of high-strength rub­ber and high­ly resis­tant plas­tic rims. The pen­e­tra­tion of soil into the slack tyre is impos­si­ble due to the well thought-out con­struc­tion. The flop­py tyres have load­able ball bear­ings. Lip seals and dust caps pro­vide opti­mum pro­tec­tion against the pen­e­tra­tion of earth or dust.

Rub­ber dampers reduce vibra­tions in seed drills

A fur­ther seed drill inno­va­tion are the rub­ber dampers which are used in many dif­fer­ent ways. When the tines trav­el through the soil, they gen­er­ate con­sid­er­able vibra­tions. To pre­vent these vibra­tions from affect­ing the entire machine, the con­struc­tion is sup­port­ed by rub­ber dampers. In this way a large part of the vibra­tions can be absorbed by the rub­ber. The result is improved run­ning smooth­ness and a low­er load on the entire machine. Our mate­ri­als exper­tise enables us to use agri­cul­tur­al machin­ery in all cli­mat­ic zones and for every appli­ca­tion.
