New Holland introduced the hybrid combine harvester CH7.70 as a competitor to the Claas Tucano for the 2021 season. It was largely identical to the CX6.90 model, but the separation was handled by two rotors measuring 54 centimeters in diameter and 345 centimeters in length. Between the 60-centimeter threshing drum and the rotors, there was an additional 40-centimeter drum. The power of the 8.7-liter engine had been increased by about ten percent to 374 horsepower. Threshing capacity was promised to be 25% higher than that of the axial combine, and broken grains were claimed to be 35% fewer compared to the axial combine.

A wider selection of length-adjustable Varifeed headers was available than before, ranging from 4.88 to 9.15 meters. Standard headers were also within the same range. The last section of the straw walker could be opened to achieve gentler threshing. The sieve surface was divided lengthwise into two parts, and air was blown from between them, which was said to improve cleaning efficiency by 15%. SmartSieve and OptiFan systems were standard; these aimed to compensate for the effects of lateral and longitudinal tilting on sieve operation by adjusting the movement of the sieve and the fan. A Laterale hillside harvesting model that keeps the machinery level was also available. The noise level in the cabin was promised to be 73 dB, and standard equipment included an IntelliView IV touchscreen where crop-specific settings could be stored. Other standard features included header tilt adjustment, a cleaning system cleaning program, adjustable straw spreader and guide plates, and automatic header adjustment.
