Abstract

The design of an existing hand jabber, developed by the Agricultural Mechanization Development Program of the Institute of Agricultural Engineering, College of Engineering and Agro-Industrial Technology, University of the Philippines at Los Banos, was evaluated using the anthropometric profile of male farmers in the province of Batangas. Thirty eight different body dimensions were collected from 80 male farmers. These measurements have direct implications to the design of agricultural machinery and workstations.The parts of the hand jabber that were evaluated were the following: handle height, total height of the jabber, handle diameter, handle length, and the distance of the actuator arm to the handle. The values of the 5ᵗʰ and 95ᵗʰ percentile were used to modify the specifications of the design of the handle jabber to increase the comfort of operation. It is recommended to modify the hand jabber with the following specifications:handle height equal to 80cm total height of jabber equal to 90cm handle diameter equal to 1¼ inches maximum distance of actuator arm to handle equal to 5cm (3cm for operating distance and 2cm for clearance) the original handle length of 14cm can be retained. It is also recommended that afield test the hand jabber with the specifications above should be conducted to determine if the farmer's desired comfort in operating the jabber is met.
