Abstract

A survey was conducted to develop an anthropometric data and working profile of male farmers in Quezon, Philippines. Thirty-eight body dimensions were obtained from 78 male farmers actual measurements. These body dimensions served as bases in evaluating the UPLB hand tractor. The working population has an average of 45.4 years old with a range of 18 to 66 years old. The age of the male farmers that are commonly involved in agriculture is 50. It was found out that different working profiles can use variability in physical body dimensions. The correlation of body dimensions were also obtained with respect to the standing height. Values ranges from 0.175 to 0.891 which means that some of the body measurements have positive correlation with the standing height.The fitness of the UPLB hand tractor and Panday Pira hand tractor to the farmers of Quezon Province were evaluated using the 5ᵗʰ and 95ᵗʰ percentile values of the collected anthropometric data. The values were considered so as to have a wider range of farmers who can use the tractor. The body dimensions considered were the hand breadth, grip diameter, forearm-hand, elbow height, shoulder height, standing height and the breadth across elbow. These body measurements were compared with the UPLB and Panday Pira hand tractor's handle height, clutch distance from the operator,force to full or push the handle vertically, handle to handle distance and the distance of the implement from the foot of the operator during operation. Based from the anthropometric data obtained and posture analysis conducted, the specification of the hand tractor must be equal or lower than the 5ᵗʰ percentile values. These values obtained are as follows: for the handle to handle distance-70cm clutch distance-77.9cm grip diameter-4.4cm and handle height- 88cm. The limits for pushing and pulling down the handle tractor are 29kgf and 20kgf, respectively. Some parts of the UPLB hand tractor were too large and does not fit the farmers of Quezon Province. On the other hand, the modified UPLB hand tractor which is the Panday Pira hand tractor is ergonomically fit for the Quezon farmers based on the anthropometric data gathered and computed.
