Ushbu tadqiqotda kassetali (plug-tray) usulda yetishtirilgan pomidor (Solanum lycopersicum) ko‘chatlarini shikastlanishsiz va yuqori aniqlikda ekishni ta’minlovchi mini-traktor bazasidagi bionik ishchi organning konstruktiv-texnologik parametrlari ilmiy asoslandi. Ekkich ishchi organi qarg‘aning ozuqa izlashdagi tumshuq penetratsiyasi bionikasiga asoslangan bo‘lib, 2 tabaqali vertikal harakatlanuvchi nayza shaklida loyihalashtirildi. Ko‘chatni yuqoridan qabul qilish va tuproqqa nol nisbiy tezlikda (vr = 0) joylashtirish kinematikasi hamda tuproq qarshiligining ikkinchi turdagi Lagranj differensial modeli tuzildi. Dala sinovlari natijalari bionik mexanizm an’anaviy tizimlarga nisbatan tuproq qarshiligini 19.4% ga, ko‘chat ildiz blokining deformatsiyasini esa 8 barobargacha kamaytirishini, unumdorlikni 5 000-6 000 dona/soatga yetkazishini va qo‘l mehnatini 80% ga qisqartirishini ko‘rsatdi.
