Agrola 1500 HST

Agrola HST trailed 2-row sprayer for spraying on plantations of berry bushes: currants, gooseberries,  raspberries, grapevines, etc. Agrola HST is a unique design, which ensures quick adjustment of the sprayer to the width of the rows and excellent coverage of berry bushes due to the use of eight (2x4) outlets for each row. Agrola HST 2-row sprayer significantly reduces the time of treatment.

Blower - is equipped with a centrifugal impeller and two-speed multiplier gearbox (2+N). Four sets of 4 outlets which contain double nozzle holders with anti-drip valve and two sets of spray tips.

Boom - 2-row, hydraulic lifting, opening and closing by electro-hydraulic valves. The range of spraying two rows with a height of up to 1.5 m, row spacing from 3.0 to 5.0 m, sixteen outlets - eight outlets per row - 4 outlets per side.

Pump - diaphragm, high pressure manufactured by a renowned Italian company Annovi & Reverberi. Model BHA150 with max flow 142 lpm and max pressure 50 bar [5 MPa] (max operating pressure 20 bar [2 MPa]) ensures receiving a full range of pressures and capacity of liquids needed to perform plant protection treatments and proper mixing of liquids in the tank.


Control unit - according to the clients' needs, we offer two equipment options:
Arag electric control unit (4 sections valves, main valve, proportional control valve) with a control box.
Arag Bravo 300s computer (electric control unit with 4 sections valves, electromagnetic flow-meter and inductive speed sensor which is installed on the sprayer wheel).

Tank - made of high quality polyethylene, contains three parts: a main tank with a nominal capacity of 1500 liters, a tank of clean water for rinsing the circuit and a tank of clean water for washing hands.

Frame and drawbar - specially designed from high quality structural steel that is protected against corrosion by hot dip galvanizing.It forms solid and durable machine base.
- steering drawbar for three-point hitch 

Axles and wheels - adjustable axle and proper selection of wheels for the terrain have a big impact on the stability of the machine, that's why we offer several types of tires:
- 340/55-16 wheels;
- 380/55-17 wheels (equipment option);
- 400/60-15,5 wheels (equipment option);

Lighting system (standard equipment) - lighting that gives visible light from a distance is a necessary addition when the machine drives on roads. Lighting system installation - rear, composite LED lamps (position, directional and stop lights) + warning triangle for agricultural machinery.
Lighting of nozzles with LED (optional equipment).

PTO Drive shaft - PTO Wide angel drive shaft (torque 400Nm, length 1010mm)
* - to drive the sprayer it is necessary to use a PTO drive shaft that has the CE mark and safety shield kit.

Working width 2-row, row spacing from 3.0 to 5.0m
Air flow capacity (max) 16 000 m3/h.
Required power: 45-60HP;
Max RPM 540
Max allowed operating pressure 20bar [2MPa]
Max allowed travelling velocity 15km/h

*- power demand depends on operating parameters; efficiency of the fan and working pressure. In a mountainous terrain or wetlands, it may be necessary to use tractors with more power.
*- the spraying level depends on operating parameters, weather conditions and "foliage of trees".
