One of the most powerful combines in the world is to receive a power boost.

New Holland’s biggest harvester, the CR10.90, will jump from 652 to 700 horsepower in 2018.

The company revealed this month it would beef up the rest of its 2018 CR Revelation harvesters, adding a range of new features to the combines, including a redesigned residue management system, improved adjustable crop flow, a power upgrade and a new colour scheme.

New Holland Australia-New Zealand combine product manager Marc Smith said the new models also lowered the power needed to separate grain by up to 75hp.

“The CR combine already holds the world record for harvesting — it is the most powerful combine in the market with the highest capacity,” he said.

“But at New Holland we are constantly looking for ways to improve our customers’ productivity and profitability.

“With the new CR Revelation range we have achieved this. The control of crop flow has been improved, assisting our customers to increase their productivity.”

The CR10.90, released in Australia in 2015, achieved a world record in August 2014 for the most wheat harvested in eight hours.

According to a New Holland statement, broader changes to its CR Revelation model would improve capacity by 10 per cent, while guaranteeing grain quality and residue management.

The new combines include up to 45 feet spreading width — adjustable from the cab — as well as twin pitch plus rotors and a fine shopper sample.

Mr Smith said the new cab-controlled remote adjustable rotor vanes would also result in class-leading crop flow control and power efficiency gains.

He said the feature, offered as standard on all 22-inch models at the top of the range, had been spruiked for its potential to improve productivity and capacity.

Upgrades also include an in-cab concave reset, to contribute to increasing the combine’s productivity and reducing downtime in case of a concave breakaway.

Improvements to the chopper — which include a reinforced rotor, longer counter knives and increased chopper speed — could also result in a finer sample and a 50 per cent reduction of long straw.

The chaff spreader was entirely redesigned, with a patented air crop flow system to replace the traditional, impact-based design.

The main frame, grain pan and beater grate, as well as the colour of the grain tank, were changed to yellow to improve visibility.

The three models at the top of the range also feature optional Twin Pitch Plus rotors with three-inch raspbars, delivering power efficiency gains ranging from 20kW in the CR8.90 to 28kW in the top-of-the-range CR10.90.

These features, together with other improvements that include higher rotor covers on the two smaller 17-inch models, the deep cut Dynamic Feed Roll and the power upgrade, deliver an increase in the CR combine’s productivity of up to 10 per cent.

DFR is now standard across the two flagship models, namely the CR9.90 and CR10.90.
