Increased Automation Focus on New Case IH Combines

Introducing more automated features is the key focus for global machinery manufacturer Case IH on its recently launched range of combines.

Giving the driver greater flexibility in how to operate the machine more efficiently with new automatic control features is the key attribute of the Case IH Axial Flow 250 Series combines

The three new models, 7250, 8250 and 9250, replace the Case IH 240 series and will go into production this October ready to be rolled out for the 2019 harvest.

Case IH have introduced a number of new automated features to enhance operator performance and ensure optimum grain quality including AFS harvest Command, in cab sieve controls and a new transmission.

August von Eckardstein, Case IH harvesting product marketing manager for Europe, Middle East and Africa, said:

These new automated features allow for more efficient control of the combine. Crop conditions vary so we wanted to introduce some automation that can recognize this and adjust itself to suit.”

“The new features are designed to enhance the performance of even the more experienced driver but also to help the less experienced get the most from the combine.”

New AFS Harvest Command Automation

A total of 16 sensor inputs are utilized in the new AFS Harvest Command technology which continuously monitors the machine and adjusts seven different settings to maximize combine performance.

Depending on the crop type and condition, the operator controls this technology via the in-cab AFS Pro700 terminal. The automation system is currently capable of working in wheat, oilseed rape/canola, corn/maize and soybeans.

The basic version of AFS Harvest Command features the proven Automatic Crop Settings (ACS) system. This adjusts operating items such as fan speed and concave clearance according to the crop type selected on the AFS terminal screen, eliminating the need to make individual element settings.  

The next version, with Feedrate Control, adjusts ground speed based on crop load to cater for the desired outcome, performance to control losses, maximum throughput, or fixed throughput.  

The top specification option is full AFS Harvest Command automation, which automatically makes threshing and cleaning system adjustments based on the same desired outcomes as Feedrate Control, with the addition of grain quality monitoring.

Rotor Cage and Sieve Upgrades

Adjustable rotor cage vanes controlled from a control switch in the cab are activated with AFS Harvest Command. The rear six vanes are linked, include a greater range of adjustment, and can also be manually adjusted from ground level. By changing the pitch of the vanes, the crop will move faster or slower through the rotor cage, tuning threshing and separation performance to crop conditions for improved efficiency.

Transmission Changes

A new hydrostatic transmission, featuring a field and a road mode and on-the-move two-speed range control, provides increased traction and means there is no need to stop and shift while working or traveling on hills.

Case IH global product manager for combines, Sam Acker, told AgriExpo e-Magazine:

We will start production of the new Case IH Axial Flow 250 Series this October and should have machines ready to introduce to most global markets for the 2019 harvest.”
