New tech enhances New Holland CR combine efficiency
New Holland celebrates 46 years of Twin Rotor CR Combine harvesters in 2021
New Holland introduced its Twin Rotor™ technology on the TR70 (145-168hp) in 1975, which has gone on to become a game-changing piece of technology in the harvesting market.
New Holland CR Twin Rotor combine harvesters feature 22-inch diameter Twin Pitch Rotors as standard fitment. Twin Pitch Rotors feature rasp bars spiralled, staggered and segmented along the entire length of the 2 rotors, commonly referred to as S³.
The CR’s twin counter-rotating rotors give the machine greater control over the threshing and separation elements by creating a thinner crop mat while ensuring smoother crop flow in a wider range of crops and conditions.
The higher rotational speed reached by Twin Rotors applies a greater level of centrifugal force to the crop which maximises separation and improves grain quality, New Holland said.
Today, the company offers four models starting with the CR7.90 with 449 peak horsepower (hp) through to the CR10.90 with a peak rating of 700hp.
In addition to the tried-and-tested Twin Rotor™ technology, New Holland’s new generation CR combine harvester models feature a range of innovative technology including the Opti-Clean™ and Opti-Fan™ self-leveling cleaning shoe systems; and Intellisense automation to offer farmers increased productivity and reduce crop loss.
Award-winning South Australian producer, Matthew Davey, introduced a new CR9.90 Opti-Clean combine on his Yorke Peninsula broadacre grain farm in 2020.
“It was the first new header on the farm since 1976,” he said. “Nigel Phillips, the Dealer Principal and Michael Glasson, the Sales Manager from the Kadina branch of our local New Holland dealership Vater Machinery had arranged a demonstration on the CR9.90 on the farm the year before.
“We’re constantly looking at what we can improve on our farm in a broadacre setting. We were running much smaller at the time, in terms of the previous combine size, and the tonnes per hour. So, we wanted the data out of the CR9.90 header, comparing the results in yield against the previous machine.”
When Davey got the yield data back from the CR9.90 and compared it with his previous machine, he found the CR9.90 to be far superior.
“The yield information we were able to download and analyse with precision farming software proved how much better it could be,” he said.
“We were able to lay out a business case for dry, average and wet years based on information coming out of the demo header while it was in our paddock plus the long history in building quality combines.
“We extrapolated those results over the whole farm, then the extra grain in the machine would be the repayment average year, with the machine paying for itself over five years.”
