Broadcasters are intended for superficial entering of firm mineral fertilizers in granulated and crystal kinds and for crops of green manure seeds.

Broadcaster RDU-1,5 is hinged and aggregated with wheel tractors of class 2,0 having VOM at 540 rpm, hydrosystem conclusions, socket for connection of light-signal equipment and automatic coupling sA-1.

Broadcaster RDU-1,5 can be aggregated with tractors of class 1,4 with restriction of loading capacity to 0,7 ton, at complete set of ballast cargoes to 1,0 ton.

Broadcaster RDU-3,0 is semitrailer and is aggregated with wheel tractors of classes 0,9-1,4 having outputs of hydrosystem, pneumodrive of brakes, VOM at 540 rpm, socket for connection of light-signal equipment and tractive coupling device (diameter with a plug).

Broadcaster RDU-8,5 (at removed broadcaster RDU-1,5) use as semitrailer for transportation and grain loading in seeders during grain crops.

Broadcaster RDU-8,5 is semitrailer and is aggregated with wheel tractors of class 2 having outputs of hydrosystem, pneumodrive of brakes, VOM at 540 rpm, socket for connection of light-signal equipment and TSU-2V.

Broadcaster RDU-7,5U is intended for superficial entering of all kinds of firm mineral fertilizers and limy fertilizers (dolomitic flour) etc.

Broadcaster RDU-7,5U is aggregated with tractors of class 2 having VOM at 540 rpm, hydrosystem, pneumodrive of brakes, electric equipment outputs and TSU-3V.

Broadcaster RDU-7,5U is equipped by two disseminating disks from stainless steel and tape conveyor with drive from broadcaster wheel. It is provide synchronization of giving of working product from broadcaster's speed. Opening and closing of dampfer, which supervise a stream of fertilizers, are carried out by means of hydrocylinder. Broadcaster is equipped with pneumatic brake system and water-proof canvas awning. Big volume tires reduce pressure upon soil and allow to maintain it in very severe conditions.

Advantages of machine design:

• Quickly rotating disseminating disks (980 rpm) by means of shovels make for granules of fertilizers optimum dispersion speed.
• Slowly rotating sprocket tedder (20 rpm) provide an unobstructed and uniform exit from bunker of fertilizers, without destroying granules.
• One steam of disseminating disks for all kinds of works - for application of fertilizers, top-dressing, boundary entering.
• Wide range of adjustment of width of application dose of fertilizers.
• High uniformity of entering.
• It is possible to use broadcaster RDU-1,5 at various width of technological track.
• Possibility of unilateral addition of fertilizers at movement on field border.
• Management of supply of fertilizer on each disk from tractor cabin.
• Application of high-quality corrosion-resistant materials at manufacturing of details contacting to fertilizers.
• Existence in accompanying documentation of tables for definition of doses of fertilizer introduction.

In 2001 at Russian Agroindustrial exhibition in Moscow disk mineral fertilizer broadcaster RDU-1,5, was awarded by Bronze medal and III-rd degree Diploma.

In branch competition "Tsaritsynsky fair" (Volgograd, 2009) disk mineral fertilizer broadcasters RDU-1,5, RDU-3,0 and RDU-8,5 was awarded by Gold medal and Winner Diploma.
