  • Overlap 1 – 8 %

  • 160 tractors with auto steering - 10 cm

  • 40 tractors with auto steering - 2 cm

  • ≈ 0,7 % of full time farmers

  • 3 Farmers do CTF on 1.000 ha.


Australia
Australia

  • 200+ farmers do CTF on 1.000.000 ha.

  • 200+ farmers consider CTF on 1.000.000 ha

  • 200+ tractors with 2 cm auto steering

  • 1.000+ tractors with less accurate auto steering

  • 20-70 % of farmers use auto steering


Measurements of accuracy- test procedure is under development

Controlled traffic farming sustainable future farming
Controlled traffic farming - sustainable future farming


Controlled traffic farming main decisions
Controlled traffic farming - main decisions

  • Working width

  • Wheel space

  • Position of tracks


Trials with controlled traffic farming
Trials with controlled traffic farming

  • Grain, Europe: -9 → 21 %

    (Chamen et.al. 1992)

  • Grain, Australia: avg: 16 %

    (Tullberg et.al 2001)

  • Energy used during tillage -70 → -37 %

    (Chamen et.al. 1992)

  • Energy used in total: - 17 %

    (Dickson & Campbell 1990)

Controlled traffic

Machine control, e.g. auto boom

Auto steering

“You don’t drive cars over flowerbeds... We’re driving much heavier machines over the soils we hope to produce crops from and it’s causing a lot of damage”. Jeff Tullberg
