The brand new flagship New Holland CR11 mix previewed at Agritechnica 2023 has been joined by a CR10 companion mannequin on the official harvest 2024 launch of the brand new Subsequent Era design, with each harvesters – constructed at New Holland’s mix Centre of Excellence in Zedelgem, Belgium – that includes modern new know-how designed to assist the biggest farming enterprises maximise output, minimise losses and scale back complete price of harvesting.
The first distinction between the 2 fashions is in energy and grain tank measurement, to make sure the brand new combines match the wants of a broad vary of huge farm enterprises. The CR11 incorporates a 20,000-litre grain tank and a 15.9-litre FPT Cursor 16 engine producing 775hp. The CR10 engine is a 12.9-litre FPT Cursor 13 producing 635hp, whereas its grain tank holds 16,000 litres. Past further energy and grain capability, the important thing options that take these combines into a brand new league by way of output, pattern high quality and loss minimisation embrace longer twin rotors and the brand new Twin-Clear cleansing system.
Extra capability from entrance to rear
From the entrance, these new flagship CR combines are designed to deal with better volumes of crop. Cutterbar widths of 10.6-15.0m (35-50ft) can be found in fastened, versatile knife, movable knife and draper codecs. Corn/maize heads of 12-16 rows are additionally out there, and unloading auger lengths may be specified to match all header widths. There are three driveline choices to satisfy all header necessities – customary with fastened drive, customary with variable drive, and a variable heavy-duty system. On the variable driveline, a CVT drive unit on the engine gearbox permits header/feeder velocity to be assorted relying on crop and subject situations. Feeder/header reversing is achieved through with a hydraulic motor on the fastened velocity driveline, and with the CVT drive on the variable velocity driveline.
The elevator is supplied as customary with entrance face adjustment and lateral tilt distant managed from the cab. From right here the crop is fed to New Holland’s confirmed Dynamic Feed Roll system, which may now be reversed – concurrently with the elevator and the rotors – within the occasion of a blockage. The DFR accelerates the crop and splits it into two even streams to feed the 2 longitudinal threshing and separating rotors that comply with. A big stone lure in entrance of the DFR may be emptied both manually or, optionally, remotely through hydraulic activation from the cab.
New Holland was the primary to launch a mix that includes two longitudinal rotors at its coronary heart, pioneering its Twin Rotor threshing and separation know-how nearly 50 years in the past, in 1975. Over time, its design has developed to make sure it meets equally evolving calls for for throughput, grain safety, grain retention and straw high quality. Within the new CR10 and CR11, the 2 600mm (24in) rotors are of elevated diameter and size, offering better capability for the crop to flow into and the grain be be threshed and separated. Every rotor options 40 customary rasp bars, eight HX raspbars and 12 spiked raspbars.
The HX items mix the peak of spiked raspbars with the profile of the usual items, with a better sidewall angle serving to speed up crop move within the transition zone of the stepped rotor cage, between the threshing zone and the separation zone. Vane angle may be remotely managed from the cab, and the brand new vane design aids crop ejection ought to the rotors have to be reversed. New rotor cages characteristic a stepped design with a broader cage and better vanes within the separation space, to permit better crop mat motion, improved separation and enhanced energy effectivity. The concave space includes two units of three light-weight threshing concaves and separation grates, and two units of six light-weight grates.
All-new TwinClean cleansing shoe
The brand new TwinClean cleansing shoe incorporates a number of options to spice up throughput and decrease grain loss. It consists of two sieve methods in sequence, every having its personal higher and decrease sieve and clear grain auger, and is predicated round a big grainpan with an elevated fallstep to the primary higher sieve. Airflow is offered by a high-power cleansing shoe fan. Two automated cross distribution mechanisms, one on the grainpan and one on the higher sieves, assure a good cleansing shoe load in all situations.
Two units of stress sensors, one on the grainpan and one on the higher sieves, repeatedly measure the cleansing shoe load and detect any anomalies in materials distribution between left and proper. A side-shake mechanism provides a lateral part to the grainpan and sieve motion which evens out the fabric over the cleansing shoe’s full width. As such, the cleansing shoe can compensate for uneven feeding and aspect slopes as much as 28%. Total measurement of the whole sieve space is 8.76 m².
