AGRICULTURAL EQUIPMENT
• Farm equipment is a group of devices designed to open furrows in the ground, shredding, spraying and fertihzing the soil.
AGRICULTURAL EQUIPMENT
Plough: agricultural equipment is designed to open furrows in the earth consists of a blade, fence, plough, bead, bed, wheel and handlebar, which serve to cut and level the land, hold parts of the plough, set shot and to serve as handle. There are various types of ploughs but the best known are:
• Mouldboard plough, formed by the grating blade and mouldboard
• Disc plough, disc concave formed by deep grooves to open • Shallow ploughing to remove the topsoil • Subsoil plough to remove the soil depth

AGRICULTURAL EQUIPMENT
Sprayer: it is a farm equipment designed to spray, is composed of a liquid tank, pressure pump, cap, mouth, tank and pressure valve, belts, hose, faucet and nozzle v^here the liquid to spray out, is insecticide, fungicide or herbicide. The hand sprayer is placed in the back of the sprayer and this has placed in the mouth and nose a special mask to prevent strong odours dismissed by the substance that expels the sprayer wdll harm.

EU - STRATEGIC RESEARCH for 2020
• Farming: The future farming in European is precision farming. There are two types, which are
• Precision livestock farming
• Precision crop farming
![Page 14: Mechanical Design in Agricultural Machines Design in... · • As seeking maximum • According to method and performance or minimal use of objectives: other means of production,](https://reader033.fdocuments.net/reader033/viewer/2022060602/605702ed90a46b201b658b49/html5/thumbnails/14.jpg)
EU - STRATEGIC RESEARCH for 2020
• Technology: Electronics, automation and robotics have been wddely used. Farm power and machinery have changed to used renewable energy source like bio-based synthetic fuel, hydrogen and fuel cell. Farm equipment will be more specialized and more optimized with high efficiency.
Note: Many EU agriculture equipment manufacturers are still SME but they are technology-drive enterprise.

AGRICULTURE in THAILAND
Sustainable Agriculture (miiPiT^^il'u):
Agroforestry (imnm'i) Integrated Farming (Lnw-i?i?w?5ww?n"u) The New Theory (mtJ^iTiqyglviJj) Organic Agriculture (tfiii^iSuTilEj') Natural Agriculture (miJ^iJiiUT^iiN^TUNttTU)

AGRICULTURE in THAILAND
Thai's Agriculture: • Both dry and irrigation farming • Small industrial agriculture
• Change from "•innfi\4" to ""wnunvnn'u" • Should be " m m " plus "'nisJTHin'w"
LEAN PRINCIPLES in THAI'S AGRICULTURE
Womack and Jones (1996) identify the following 5 components of Lean:
1. Specify Value
2.Identify the Value Stream
3. Make Value flow without interruptions
4. Let the customer Pull Value
5. Pursue Perfection
• Perfection is sought through the use of standards, kalzen/kaikaku, 5 Why's, 5S's, 5M's, and other nnethods of continuous improvement
