The 3 largest Case IH Axial-Flow combines have gone ‘high tech’ with new sensor monitoring systems and on-the-go settings automation.
These features are introduced alongside a slicker hydrostatic transmission, new brakes and front axle diff lock control, a heavier-lifting feeder house to handle wider cutting tables and a tilt function to set the knife angle for different crops.
AFS Harvest Command Automation encompasses several features (some of which are available individually) to automate the top 3 combines in the Axial-Flow range for consistent performance throughout the day and to support inexperienced operators.
Once grain loss, throughput and grain quality parameters have been set, the new optional system gathers data from 16 sensor inputs to monitor and adjust as necessary key functions within the machine.

These include forward speed to regulate crop intake – a feature that can also be used on its own; the angle of crop spiralling vanes on the threshing/separation rotor to regulate dwell time; fan speed for the chaff separation element of the cleaning process; and sieve settings.
The settings chosen are based on the established system for remotely adjusting the set-up for different crops via the AFS Pro 700 touch-screen terminal – but with AFS Harvest Command Automation, the settings are continuously monitored and adjusted to achieve optimum output within grain losses and quality limits.

Case IH says the patented imaging technology uses illuminates grain with UV, blue, green, red and infra-red light to more accurately identify broken grain by detecting exposed starch, as well as impurity levels.
The updates have prompted a change of designation to 250 Series Axial-Flow, comprising 3 models with engine power outputs unchanged at 498hp, 571hp and 634hp.
