PAES

Philippine Agricultural Engineering Standards, a set of 13 volumes with 271 standards covering agricultural machinery.

Walking-Type Agricultural Tractor (WTAT)

A type of agricultural tractor, often powered by humans, used for farming tasks.

Agricultural Tractors (PAES Standards)

PAES standards (e.g., PAES 109, 110, 111) specify requirements and test methods for different types of walking tractors.

AMTEC

Agricultural Machinery Testing and Evaluation Center, responsible for testing agricultural machinery in the Philippines.

Study Notes

Philippine Agricultural Engineering Standards (PAES)

  • PAES stands for Philippine Agricultural Engineering Standards
  • There are 13 volumes of PAES
  • PAES has 5 machine categories
  • There are 271 PAES standards

Agricultural Tractors

  • PAES 109:2000 specifies requirements for walking-type agricultural tractor classified as pull-type
  • PAES 110:2001 specifies minimum requirements for walking-type agricultural tractor classified as rotary tilling-type
  • PAES 111:2000 specifies methods of test and inspection for walking-type agricultural tractor

Agricultural Machinery Testing and Evaluation Center (AMTEC)

  • AMTEC stands for Agricultural Machinery Testing and Evaluation Center

Walking-Type Agricultural Tractor (WTAT)

  • Parts of pull-type WTAT include human power, which is a poor source of power (0.1hp under favorable conditions)
  • A person can cultivate only 1 ha of land using hand tools

Draft Animals

  • In 1976, the population reduction of draft animals in the Philippines was caused by hoof and mouth disease
  • The optimal draft power of a carabao is 15% of its total weight

Electric Motors

  • Electric motors are commonly used as stationary prime movers for processing farm products and by-products
  • Alternating current (AC) motors use an electric current that reverses its direction at regular intervals
  • Service factor indicates the maximum load that can be successfully carried by the motor if operated continuously
  • Open type enclosure is used in electric motors to allow easy movement of air in and out of the windings

DC Motors

  • The commutator is an electric motor part only found in DC motors, which overturns the direction of electric current
  • Field pole is the interaction of two magnetic fields that causes rotation in a DC motor
  • Armature becomes electromagnetic when current goes through it

Internal Combustion Engine

  • It is a type of heat engine where fuel is ignited and burned inside the cylinder
  • Internal combustion engine has parts such as piston, piston rings, piston pin, connecting rod, bore, and auxiliary parts and accessories

Induction Motor

  • It is the most popular motor in industry due to its ruggedness and lower maintenance requirements
  • The two main electrical components of induction motor are rotor and stator
