ASA-Lift Wide Span (Gantry tractor)

This article from 2014 has been recovered from the closed ctfeurope.com site. Sorry for any links not working.

Why are wide span tractors interesting?

Agricultural machines have grown in size over the past 60 years. They are now so heavy that they damage the soil in the field, and they take up  lots of space on roads.

Wide Span machinery solves both these two problems.

A wide span machine is long and narrow with road transport. The field is wide, so it makes little trace
A wide span machine is long and narrow when in road transport. and wide in the field, where it leaves few wheel tracks. CAD Drawing: ASA-Lift

CTF Europe overgår til Smart Agri-Systems Platform

Fra 2015 er de engelske aktiviteter i CTF Europe flyttet over i netværksamarbejdet “Smart Agri-Systems Platform” (SASP).  Med et medlemsskab af SASP vil du også fremover modtage nyheder om faste kørespor.

Agrovation, CTF demonstrations- og udviklingsfarm for Horsch, 3.000 ha i Tjekkiet.

Maskinproducenten Horsch afprøver og udvikler gerne nye maskiner på egen jord. Et 12 m faste kørespor system er implementeret på den 3.000 ha store Tjekkiske ejendom AgroVation. Ved den 2. internationale CTF konference, der foregår d. 18. og 19. juni 2015 er der besøg på ejendommen. Se her, hvis du vil med.

CTF i kartofler, Skåne d. 27. november

Er du interesseret i kartofler og faste kørespor, så har dette måske din interesse.

Et kartoffelseminar arrangeret af Syngenta, der slutter af med et indlæg faste kørespor. Jeg har fået lov at invitere medlemmer af CTF Europe til den sidste del, hvor programmet er:

10:30-12:30 Application Technique (Session leader: Johan Henrysson)
