    Performance evaluation of the Grass cutter modified into a Rice Harvester
    (Don Mariano Marcos Memorial State University - North La Union Campus, 2010-03) Biscarra, Lenie Rea E.; Lazaga, Aldwin P.
    The study was conducted to modify the grass cutter into a rice cutter harvester to evaluate its field performance in terms of its actual field capacity, theoretical field capacity, field efficiency and fuel consumption and its adaptability in dry and wet field condition. Locally, grass cutters spread out and most farmers used it only in cleaning the field, trimming and cutting grasses. Hence, modification of the grass cutter into a rice harvester was one way in meeting the needs of farmers that is to save on labor cost, increase productivity, and lessen the difficulty in rice harvesting and has a portable rice harvesting machine. The construction of the attachment was done at the Department of Agricultural Engineering, DMMMSU NLUC, Bacnotan, La Union and was welded at the Maala's Welding Shop at Say-oan, Bacnotan, La Union. The attachment was made of steel shaft and steel plate welded together and a galvanized iron sheet secured by rivet. The testing of the machine was done at the farm located at Brgy. Barrio-An, Tagudin, Ilocos Sur. It was tested on dry and wet field to determine its adaptability. Based on the result of the study, the machine has an actual field capacity of 6.96 m²/mins. (0.33ha/day) in the dry field condition and 6.63 m²/mins. (0.32 ha/day) in wet field condition and it has a fuel consumption of 0.57 li/hr in dry field and 0.62 in wet field. The total cost of the attachment was P 723.10 including labor cost. The initial cost of the attachment was P 723.10. The rice harvester has initial cost of P13, 523.10 with a machine income of P 42,429.92/ha-yr in dry field and P 36,775.58/ha-yr in wet field.
