# Agro-Malz machinery: equipment and technology from Żuławy The AVR Puma 3 harvester, Ecorobotix ARA sprayer, DOWNS CropVision optical sorter and a 13,000-tonne store. See how we grow, harvest and pack our onions. ## Harvest ### AVR Puma 3 The self-propelled harvester that brings in our potatoes and onions. The AVR Puma 3 is our self-propelled four-row harvester. A 469 hp Volvo engine and an 8-tonne bunker let us work fast and without stops, at night too. We dig our potatoes with it, and at onion harvest it picks up the windrows laid earlier by the windrower and unloads on the move onto trailers, without stopping. - Type: Self-propelled four-row harvester - Engine: Volvo, 469 hp - Bunker: 8 t - Use: Potatoes and onions from windrows ### Grimme WV 180 The windrower that lays our onions in windrows to dry. Our onion harvest starts with the Grimme WV 180. This mounted windrower lifts the onions across a 180 cm working width, cleans them of soil on two rod conveyors and lays them in even windrows, where they dry in the field. It is the first stage of our two-phase harvest: the harvester then follows and picks the onions straight from the windrows. - Type: Mounted onion windrower - Manufacturer: Grimme - Working width: 180 cm - Role in harvest: First stage of the two-phase harvest, windrows for drying ## Tractors ### Fendt and John Deere tractors A fleet from 155 to 415 hp, guided by GPS to the centimetre. Our fields are worked by Fendt and John Deere tractors. We run Fendt 942, 936, 828, 724 and 620 Vario. Alongside them work a John Deere 8RX 410 on four tracks, which compacts the soil less, and a John Deere 6930 Premium, used among other things to haul onions. All of them are guided by GPS with RTK correction, so every pass is straight to the centimetre. - Power range: 155-415 hp - Drive: Wheeled plus the tracked John Deere 8RX - Guidance: GPS with RTK correction ## Guidance and precision ### Ecorobotix ARA A spot sprayer that sees every single plant. The Ecorobotix ARA is an ultra-precise sprayer. Cameras and AI tell the crop from the weeds, and 156 nozzles across 6 metres spray spot by spot, on a 6x6 cm grid, only where needed. The main crop stays completely untouched, the produce is better quality, and we use around 70% less chemicals. It is one of only three machines like this working in Poland. - Working width: 6 m - Spray grid: 6x6 cm - Nozzles: 156 - Chemical reduction: approx. 70% ### Trimble GPS with RTK correction Guiding machines to centimetre accuracy. We guide our machines across the field with Trimble GPS and RTK correction. The real-time corrected signal gives centimetre accuracy, so we drive evenly pass after pass, with no overlaps or gaps. That saves seed, fertiliser and fuel. - Type: Satellite guidance - Manufacturer: Trimble - Accuracy: approx. 2-3 cm (RTK) - Benefit: Fewer overlaps, lower costs ### John Deere Auto Pilot Automatic parallel steering for the tractor. The John Deere Auto Pilot steers the tractor in parallel automatically. The operator watches the work while the machine holds the line. Together with RTK correction and variable-rate application it is the backbone of our precision farming: even work, less fatigue and lower fuel use. - Type: Automatic steering - Manufacturer: John Deere - Function: Parallel guidance - Works with: GPS RTK, variable rate ## Storage ### 13,000-tonne onion store Our own store with ventilation and drying. We keep our onions in our own store with a capacity of around 13,000 tonnes. Controlled ventilation and drying keep the skin dry and the onions sound for many months. That lets us time our sales, and together with set-grown onions coming off the field in early summer we supply onions all year round. - Type: Vegetable store - Capacity: approx. 13,000 tonnes - Equipment: Ventilation and drying - Benefit: Supply all year round ## Sorting and packing ### DOWNS CropVision optical sorter Cameras and AI sort every single piece. We sort our onions, potatoes and red beets on the DOWNS CropVision optical sorter. Industrial cameras and AI scan the whole surface of every piece, a full 360 degrees, and reject stones, soil clods and pieces with defects. The machine handles up to 100 tonnes an hour, so large batches move fast and the buyer gets clean, even produce. - Sorts: Onions, potatoes, red beets - Technology: Industrial cameras and AI, 360-degree scan - Capacity: Up to 100 t/h - Manufacturer: DOWNS ### Onion packing line and palletiser Automated sorting and packing. We sort and pack our onions on an automated line, and a palletiser stacks the finished packs. We pack loose, in big bags and in sacks, choosing the calibre and format to suit the buyer. Automation gives repeatable quality and fast turnaround on larger orders. - Type: Sorting and packing line - Formats: Loose, big bag, sacks - Added: Palletiser - Benefit: Repeatable quality, fast delivery
