Controlled Traffic Farming
At
Lodge Farm
Paul Cripsey
Farms manager
Cropping
• Combinable crops 485 ha.
• Onions-shallots 160 ha.
• Potatoes 65 ha.
Background
• Onion and potato production at Lodge
Farm utilises a wide variety of soil types
• Concern over the ever increasing size and
weight of modern farm equipment
How do we deliver CTF?
• A challenge!
• System is based on 1.83m!
• Suits onion and potato production
• All existing machines based on 1.83m
• All new onion investment based on
3*1.83m
• CTF now based on multiples of 5.49m

Tracking is extensive every
year
• Rake, disc x2, drill, roll, harvest
• 127% tracking
Typical min-till system
Introduction to CTF
• Onion and Potato production has used
seasonal trafficking systems for over 20
years
• Steering guidance system already
established (SF2).
• Met Tim and introduced to CTF, and the
simple principle of organising our traffic
lanes seemed a logical way forward
• CTF confines all tracks to least possible area of
permanent traffic lanes
What is CTF?
– CTF is a traffic management system– it’s not prescriptive about tillage
Planning
• 2 self propelled harvesters
• 3 trailed harvesters
• 3 windrowers
• 3 planters/drills etc
• All using a bedwidth of 1.83 metres, this
had to be the base for any CTF system

How do we deliver CTF?
• Base width is 1.83m*3=5.49 metres
• Flatlift increased to 3.66 metres
• Corn drill decreased to 5.49 metres
• Sprayer increased to 27.5 metres
• Combine header increased to 12 metre to
cut 10.98 metres
• Topdown increased from 5.5m to 6 m to
work at 5.49 m
• SF2 signal upgraded to RTK
CTF
The remaining challenges
• Implement steering essential for working in
1.83m beds
• Harvester wheeltracks do not match our
system
• Combine is 2.7 metres!
• Onion harvester is 2.73 metres
• Potato harvester is 2.7 metres
• Can we move 30,000 tonnes from our
fields without damage to the soils?

Conclusions
• Controlling traffic is a logical way forward
• Can deliver sustainability for our industry
• Has its challenges, as machine
manufactures are not delivering with CTF
in mind.
