As harvester width has increased, the need for leveling the harvester has become a key component in delivering a quality product. During normal operations, harvester weight dynamics are constantly changing: tank full, tank empty, boom full, boom empty, etc. Changing field conditions from dry to wet further magnify these dynamics. With Active Depth Control (ADC), your digging depth becomes more than a best guess.
The ADC monitors the digging depth of the harvester continually. The ADC allows you to set and adjust the harvester's hitch cylinders and rear cylinders to match digging depth across the machine. This on-the-go adjustment prevents hundreds of tons of extra dirt from being introduced to the harvester.
Using a touchscreen display in the cab, the Active Depth Controller can be set to a depth-automatically instructing the valve block to make adjustments to hitch and axle cylinders. This depth can then be further adjusted using either the touchscreen display or a joystick in the cab of the tractor.
The depth controller works using two wand sensors, mounted on the front bar of the harvester. These sensors send readings to the hydraulic system attached to the rear struts to keep digging depth constant throughout the field.
Active Depth Control is currently offered as an option on Amity Technology 8 and 12 row harvesters.
