Steering
Methods to evaluate steering performance of agricultural tractors
Søren Liljenberg
Friday 8 November, 15:00
Farmers want faster tractors, which poses increased safety concerns. A higher level of steering control is necessary in order to ensure operator safety. However, it’s difficult for design engineers to test and evaluate steering performance under high-speed conditions.
This presentation will outline new testing methods — using high-speed test tracks, steering robots and biometric tests — that can better quantify operator effort for high-speed steering maneuvers.
Søren Liljenberg is Steering Sales Manager at Danfoss Power Solutions, where he’s worked his entire professional career. He held positions as a Sales Development Manager, a Key Account Manager and a Product Management and Business Area Manager for Sensors Technology. Liljenberg earned his bachelor’s degree in mechanical engineering and his Engineering Business Administration from the University of Southern Denmark.
Front loader
Optimization of tractor front loader for improved design freedom and increased operability
Thomas Heegaard Langer
Saturday 9 November, 09:00
OEMS are looking to improve operator comfort and productivity. For agricultural equipment specifically, tractor front loaders present a prime opportunity to improve machine design.
This presentation will showcase a comparison study of a tractor front loader with and without operator assistance features performing typical agriculture application tasks. It will also outline how to measure the impact of these features for yourself, as well as how to overcome design restrictions when implementing sensors and control schemes.

eSteering
Overcoming design challenges of electro-hydraulic steering systems
Tom Rudolph
Saturday 9 November, 14:30
Electro-hydraulic steering solutions provide a lot of great benefits for farmers. Auto-guidance improves productivity and enables controlled-traffic farming, variable steering ratios improve operator comfort, and four-wheel steering sets a new standard for machine maneuverability. However, these solutions can be difficult to design, deploy and test.
This presentation will provide a practical tool chain to support agricultural machine manufacturers, which includes guidelines for selecting sensors, hydraulic components, steering inputs and safety solutions.
