Combine harvester. Prompted by the need for faster, cheaper and more efficient harvesting methods than reapers or strippers, many attempts have been made to introduce imported rice combines in the Philippines but these were unsuccessful because the imported models were expensive for rice farmers and big and heavy for small wet paddy plots characteristics of Philippine rice fields. In 2002, however, PhilRice adapted a Chinese combine design which harvests and threshes paddy grains in one pass. The machine, now fitted with cleaning and bagging components, is small and lightweight for small wet paddies and easy to operate with one person to maneuver and another person to attend bagging. It has a capacity of 1 ha/d and comes with rubber tires that can be changed into steel starwheels for wet muddy fields. The machine is powered by a small
