3 3 Technical data of sprayer 33 m working width. 3 nozzles grouped together in one switching unit. Pendulum range up to 10. Boom height adjustment: 520 mm 2600 mm, continuously. 4200l tank. Electronical contents indicator displayed on terminal and control centre. 572 l rinsing water tank. Fig.1: Overview. Diaphragm pump type: Altek P500 with 453 l/ min at 5 bar. 2.0 m 2.25 m track width. Axle pivot steering. Ground clearance 600 mm (drawbar) and 750 mm (axle) with 520/85R38 tyres.

4 4 Description of sprayer Fig.2: View of the pump unit and filling connections. The framework of the sprayer is made of steel profiles with the tank situated on the top. The axle has a adjustable track width of m. It is designed for a road speed of 40 km/h. The sprayer has a rigid drawbar which can be delivered with different mounting systems. Track following is realized by an axle pivot steering. The spray tank with a nominal volume of 4200 l is made of polyethylene and is constructed without splash walls. The tank keeps an over volume of 11.8 % to hold back foam. The tank can be filled by the sprayer pump with up to 500 l/min. For the inner tank cleaning two rotating nozzles are mounted in the tank. The pressure agitation system is realized by s set of injection nozzles situated on the bottom of the tank. The agitation can be switched on and off by the spray computer control board in the drivers cabin. The introduction of plant protection product and the rinsing of empty plant product cans can be done via a retractable induction bowl on the left sprayer side. This is equipped with 2 rotating cleaning nozzles and one nozzle to produce a vortex in the outlet area. The clean water tank for rinsing and diluting holds a volume of 572 l. It is also made of polyethylene and is placed below the main tank Fig.3: Pulled out induction bowl on the left sprayer side.

5 5 Description of sprayer Fig.4: Unfolded boom with nozzles in protected positions. of the sprayer. It is equipped with a tube contents indicator without contents markings. The spray liquid pressure system of the sprayer is based on a diaphragm pump type Altek P500 which is driven via the PTO-shaft. The lateral folded 33 m boom is made from welded aluminium profiles. The boom is equipped with single switching nozzles, but in the sprayer software always 3 nozzles are grouped together. So the sprayer has 22 switchable nozzle sections. The spray liquid circuit is designed as a closed circular pipeline. So the sprayer can work without non dilutable residuals. The nozzle height can be adjusted indefinitely between 520 mm and 2600 mm. The pendulum range of the boom is +/- 10. The boom is divided in 8 mechanical sections, with the outer 3 m sections with obstacle give away function. Ultrasonic sensors make an automatic controlled boom height adjustment possible. Thanks to the design of the lower boom profiles, the nozzles are well protected against ground contact. All functions of the sprayer can be controlled by the terminal with touch screen display at the drivers place Ecotronic Plus. Fig.5: Control centre and induction bowl at the left sprayer side.

6 6 Description of sprayer With the switch box and terminal in the driver`s cabin all necessary information like for example manual or auto mode, current spray rate (l/ha), driving speed, active spray sections, flow rate, sprayed amount, sprayed area, remaining tank contents, remaining area or distance can be displayed or adjusted. The display is also readable in direct sunlight. For manual operations of the boom the switch box can be used. It provides the functions for: folding and unfolding of the boom and spaying ON/OFF, spray pressure, adjustment of boom height or inclination of the boom.

This procedure was developed by the competent testing authorities of the European countries participating in ENTAM and is based on the standard EN ISO This test is only a technical performance test which takes place without an accompanying field test. The test results apply only to the tested appurtenances of the sprayer. Statements on the behaviour of the sprayer with different appurtenances cannot be derived from these results.
