Grænmetissáber er mjög skilvirk og nákvæm landbúnaðarvél, aðallega notuð til að sá litlu fræi. Kjarnahluti þess, nákvæmni fræmælingarbúnaðurinn, hefur mikla sáningarnákvæmni (villuhlutfall<5%) and low seed breakage rate (<1%). It is suitable for 12 types of crops, including rapeseed, sesame, and alfalfa. The seed box capacity is 2kg, and the operating efficiency reaches 6-8 acres/hour. This model is equipped with a 12-level seeding rate adjustment system, achieving precise seeding control by adjusting the number of seed metering holes (e.g., a sowing depth of 10mm is recommended for rapeseed). Before sowing, the furrow opener pressure calibration and seeding rate test must be performed. During operation, the purity of the seeds must be maintained (fertilizer must not be mixed in). The sowing depth and seed metering status should be monitored in real time. The furrow opener and seed delivery tube residue should be cleaned daily to maintain optimal operating conditions.
