Exciting updates for the Case IH AFS tractor

Implement control of tractor functions and automatic headland turns are now possible with the addition of higher-level Isobus communications protocols to Case IH 165-270hp Puma Multicontroller powershift and CVX stepess transmission tractors.

Isobus Class III enables 2-way data transfer between the tractor and any compatible implement, which means that in addition to the control of implement functions via an Isobus virtual terminal on the tractor, the implement can feed data to control tractor functions.

Multicontroller joystick

This new functionality can be used with the baler, for example, to regulate steering along a narrow swath to ensure even filling of the chamber. It can control the tractor’s ground speed based on baler load sensing to optimise throughput in swaths of variable size or density.

In addition, Puma operators can configure all buttons – except those operating the transmission – on the Multicontroller joystick and the electric spool valve paddle switches to operate any Isobus implement function to suit their particular requirements or preferences.

Updates to guidance functions operated through the AFS 700 terminal include new tramlining display features and A-B lines extended into corners.

AccuTurn: Automatic headland turning

Automatic headland turning has been added to the Case IH AccuGuide system to relieve operator workload.

The new tramlines display identifies by colours which passes need or have had a tramline set down.

Parameters such as headland width, turning curve shape and the turn starting point can be adjusted to suit different fields and implements, and turns can commence using AccuTurn once the headland management system has completed its tasks – such as raising an implement out of work and disengaging 4-wheel drive.

AccuTurn works with existing AccuGuide systems using AFS 700 terminals and requires a dealer-supplied unlock code.

Extended A-B lines provide guidance into corners – previously, they were rounded off.

Colour coding with AccuGuide

In addition, AccuGuide updates include a new ‘square corner’ function (previously they were rounded off) and a new 3D field map display uses colour coding to identify passes in which a tramline is required or has been set, which saves the operator having to count passes. Tramline functions can now be used simultaneously with swath skipping, which allows sweeping turns with narrow mounted or large trailed implements.

AFS AccuTurn can be activated once the headland management system has completed its tasks to provide automatic steering to the next pass.
