520	3		_aFor rice fields situated in low-lying areas where water is usually contained, the soil is usually soft, and it has a low bulk density thus making it float over water. This type of soil is locally known as "laboy" and it is famous for its peat-like properties and depth of ranging from 40 to 100 cm. However, this type of soil is very difficult to prepare even with the help of water buffalos and conventional two-wheel hand tractor, so farmers manually invert or trample the weeds by feet. In Aurora, there is estimated 1000 hectares of laboy that can be made more productive with the help of proper and suitable tillage equipment. To help eliminate the drudgery of manual land preparation and solve the limitations of the existing hand tractors and hydro tillers, the researchers developed a ride-on floating tiller. The machine was tested in Limay, Bataan. It was demonstrated to farmer-cooperators to get their feedbacks for further improvement of the tiller. The prototype was designed with an operator seat on the buoyant machine body, a pair of drum type rotovator, and a pair of paddle wheels which will push the machine forward and allows for left and right steering. In plots with tall weeds, first-pass rotavating could be done faster if the operator walks behind the tiller. Mean field capacity for the first pass was 1.9 ha/day. After the first pass, a second pass, ride-on operation could be continuously done if the mud depth is at least 50 cm and there is adequate pond water. The commercial model should also be made more versatile by equipping it with pneumatic tires so that road travel would be an added feature. _bAuthor's Abstract
