Drivers of Agricultural Engineering and Technologies

Agricultural machinery is industrial key sectorof 21st century

Shifting reputation of Agriculture / new paradigma

Need for Sustainability

Dramatical increasing need for higher energetic efficiency and CO2-reduction

Emission regulations

Dramatical increasing need for higher labor or economicalefficiency: Automation technology



Automation – Why?Improve SustainabilityReduce InputsEnhance ProductivityReact on Changing Ag Labor Availability:

Overall Facts1. Farm consolidation drives higher need for non-family farm workers

2. Seasonal workers with growing importance in EU 25

3. Depopulation of rural areas lead to farm labor shortage

4. High-tech machines, complex production processes

and strict production regulations require skilled labor

Availability of skilled labor is major issue and not higher labor costs

Implications1. Increasing need for new technologies (automation)

2. Focus on operator / interface and “ease of use”

3. Increased need for training



Tractor/Tractor-Implement Management is Automation But why do we need automation?

Reduce inputsImprove efficiency and sustainabilityEnhance productivityReact on changing ag labor availability



1. Power increase has been stagnating2. New functionalities3. Changing of power transmissions4. Higher level of automation / machine intelligence5. Integrated application management (*), teleservice, documentation …6. Enhanced HMIs / ergonomics

General trends in development of ag machinery:

1. Power increase has been stagnating2. New functionalities3. Changing of power transmissions4. Higher level of automation / machine intelligence5. Integrated application management (*), teleservice, documentation …6. Enhanced HMIs / ergonomics (*) Quite famous: Precision farming – but that‘s not all …

Automation is a dominating trend



1. Farmers require steadily increasing productivity2. Safety, comfort and ease of use3. Fulfillment of individual life style needs

What do customers want from automation (electronics)?



1. μ-electronics 2. Sensor technologies 3. Communications

(currently CAN + ISOBUS)

Current state of the art:Highly integrated,intelligent and communicating functional elements

The ISOBus-Class 3 VisionBasic Assumptions

ISO 11783

• Higher productivity through higher speeds and faster control than human reaction

• Higher production quality and safety by higher process stability• Reduces load on operator (physical and mental relief)

Another set of trends

This is nothing else but …• a higher level of automation / machine intelligence• integrated application management



Autonomous Testing



⇒ Because of safety issues

⇒ Because of a lack of functional safety (functional stability)

Why don‘t we have autonomous vehicles?

• But driverless vehicles are the safest vehiclesfrom the driver‘s prospective

• But operational setting is endangered seriously

• Example: So long as there might be a pick-up (trailer) plugging a (service) person will be needed

• Tractor driver might have different tasks in the future

Automation will „attack“ that gap



Parallel tracking is just an example . . .

Advantages of AutoTrac

• less overlaps and skips• full working width and header width• straight rows in all weather conditions• more operating comfort• physical and mental relief• detection of critical situations

• Approach to field borders• (Static) obstacles

Itec Pro • Precise tractor guidance

• Automated implement and PTO controls, ground speed, and end turns at headland and interior boundaries.

• implement functions performed consistently on the headlands every time.

• reduction of input costs such as fertilizer, seed, and fuel by reducing headland skips and overlaps.

• Provision of additional accuracy by automatically guiding the tractor during headland turns

• Machine positioning correctly for the next pass through the field.

• Better effiency• Better coupling• Enhanced functionality• Independant drives



A last „side“ aspect – requirement for ease of use

• Higher automated systems are more complex• In spite of this, they must be easier in handling• This is not „a nice to have“ but a must and• a strong requirement to HMIs

• The driver must stay “The Lord of the Machine”.• The driver will handle the process …• … getting more and more a manager of• … process data acquisition, • … process data administration and • … process optimisation
