New Holland 975 Combine

[Abbie Pilz]

NewHolland designed the Harvest Suite Ultra cab with more comfort and ease so you stay refreshed and work with precision, even during long days and nights harvesting. This 131-cubic-foot cab gives you plenty of space, and at 73 decibels, it is still the quietest cab on the market.

Larger grain tank sizes perfectly match the CR REVELATION's high capacity, for less frequent unloading and increased productivity. The extra-long unloading auger matches the performance of the CR REVELATION combines with the widest headers.

The primary difference between the two models is in power and grain tank size, to ensure the new combines match the needs of a broad range of large farm enterprises. The CR11 features 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 generating 635hp, while its grain tank holds 16,000 litres. Beyond additional power and grain capacity, the key features that take these combines into a new league in terms of output, sample quality and loss minimization include longer twin rotors and the new Twin-Clean cleaning system.

New Holland was the first to launch a combine featuring two longitudinal rotors at its heart, pioneering its Twin Rotor threshing and separation technology almost 50 years ago, in 1975. Over time, its design has evolved to ensure it meets similarly evolving demands for throughput, grain protection, grain retention and straw quality. In the new CR10 and CR11, the two 600mm (24in) rotors are of increased diameter and length, providing greater capacity for the crop to circulate and the grain be be threshed and separated. Each rotor features 40 standard rasp bars, eight HX raspbars and 12 spiked raspbars. The HX units combine the height of spiked raspbars with the profile of the standard units, with a greater sidewall angle helping accelerate crop flow in the transition zone of the stepped rotor cage, between the threshing zone and the separation zone. Vane angle can be remotely controlled from the cab, and the new vane design aids crop ejection should the rotors need to be reversed. New rotor cages feature a stepped design with a broader cage and higher vanes in the separation area, to allow greater crop mat movement, improved separation and enhanced power efficiency. The concave area comprises two sets of three lightweight threshing concaves and separation grates, and two sets of six lightweight grates.

The CR11 grain tank holds 20,000 litres, with an unloading rate of 210 l/sec, while the CR10 tank holds 16,000 litres and has a 159 l/sec unloading rate. Cross-auger shut-off allows the unloading auger to be fully emptied even when the grain tank still holds grain. On the CR11, an option allows unloading speed to be reduced by 50% by disengaging the front cross auger, aiding topping-off of trailers. All unloading augers feature a pivoting spout, to aid even filling and allow tractors to keep on track.

CR10 and CR11 combines can be equipped with either a standard integrated chopper or a high hood-mounted fine-chop unit. While the first of these is intended for dry conditions, the high hood-mounted unit is targeted at users needing to process high straw volumes to a fine chop and distribute material across a wide cutting width.

The standard integrated chopper features 60 fixed blades which work in conjunction with 52 counter knives working at 3,000rpm for chopping, or at 800rpm for straw swath laying. Manual adjustment of the counter knives is standard, and remote hydraulic adjustment optional. A driven roller assists straw ejection when swathing, or into the spreader impellers when chopping. The two hydraulically-driven 800mm impellers, each equipped with three paddles, spread chopped material at widths up to 15m (50ft). An oscillating deflector behind the spreaders creates a dynamic pulsating effect on the residue spreading to ensure even distribution over the full cutting width.

The high hood chopper option leads with a 500mm beater with two rows of spikes and two rows of blades, plus a non-perforated beater pan. This is followed by a six-row chopper with 88 flail knives and 67 counter knives. The chopper can operate at low (900rpm) or high (3,600rpm) speed, with a neutral position for free movement when servicing is required. Remote chopper speed selection is optional. The pair of hydraulically-driven 970mm-diameter impellers on this unit each feature five paddles, capable of distributing material at up to 18m (61ft). As on the standard unit, an oscillating deflector is again fitted behind the spreaders on the high hood chopper, to dynamically pulse the residue across the full cutting width. The IntelliSpread option uses radars to continuously assess the full width of the residue spread and automatically adjust left and right spreader speed to guarantee full width spreading. Further options include remote selection of chopper door position, chopper gears and counterknives. Also optional is a chopper load indicator, which provides information on chopper power consumption, allowing chopper power efficiency to be assessed in relation to chop length so the operator can select the optimal balance between power consumption, chopping quality and throughput capacity.

Elsewhere in the revised cab, changes include new-style brake pedals and foot pegs, a luxury steering wheel and premium cloth or leather seats, plus new multizone climate control with floor level air ducts. A new Bluetooth radio allows operation of the radio and a mobile phone via the radio control panel in the roof liner, or one of the IntelliView 12 touchscreens. Externally, new mirrors provide a wider view angle, with the right-hand unit optionally electrically foldable, while windscreen access steps aid glass cleaning.

New CR10 and CR11 combines are equipped with precision farming technology packages designed to match the needs of the largest farms. A Core PLM Intelligence package covers the most commonly-specified requirements, such as IntelliSense, where automatic adjustments occur according to the harvest strategy chosen by the operator, whether limited loss, best grain quality, maximum capacity, or fixed throughput. The second option is an Advanced PLM Intelligence bundle, aimed at those with the most advanced demands.

Correction signal packages for IntelliSteer automated steering and other functions such as yield and moisture mapping are available from the factory in two accuracy levels with three delivery options.

Via the optional IntelliField software, at no cost owners and operators are instantly provided with in-field data and can share boundaries, guidance lines and coverage data where multiple machines are operating in the same field.

The CR10 and CR11 feature a two-speed hydrostatic transmission and TerraLock semi-automatic diff lock which is engaged manually and disengaged automatically depending on steering angle and forward speed. Models specified with SmartTrax are available with three track belt width options of 660mm/26in, 810mm/32in and 910mm/36in, with rubber or hydraulic cushioning. Respective overall machine widths are 3.49m, 3.79m and 3.99m. For certain markets a wide beam configuration is available in combination with 910mm/36in tracks, with an overall machine width of 4.8m

The engine in the new CR10 is a turbocharged six-cylinder 12.9-litre FPT Cursor 13 fed by a 1,300-litre fuel tank, while the powerplant in the CR11 is the 15.9-litre FPT Cursor 16, also a six-cylinder turbocharged unit, with a 1,500-litre fuel capacity. Respective maximum power outputs are 635hp and 775hp. A new design layout sees the engines installed longitudinally in the same direction and at the same angle as the rotors, for maximum efficiency, with cooling air being drawn from behind the grain tank. The CR10 features two cooling fans, with three on the CR11. All exhaust manifold/turbo/after treatment installation is full isolated to reduce surface temperature of hot components. Harvesting engine speed is 1,900rpm, resulting in subdued noise and minimized fuel consumption. In road mode, engine speed is 1,300rpm, for maximum travel speed with minimum fuel consumption and noise.

An optional engine air compressor comprises an engine-mounted single cylinder compressor and reservoir with 10m coiled hose and air gun stored next to the tool box. This supplies five outlets, located at the cab door entry, below the operator platform, next to the battery box, in the engine area and at the rear ladder. Engine accessories include brushes installed on each rotary dust screen, providing continuous cleaning in heavy dusts produced by crops such as maize/corn and sunflowers.

On the all-new hydraulic system on CR10 and CR11 combines, hydraulic hose routing has been redesigned in dedicated routing highways to improve access and simplicity. All harvest hydraulic drives are disengaged mechanically via a clutch in the main engine gearbox at start-up or during road travel, reducing drag and saving up to 20hp/15kW of power. The use of load-sensing pumps further reduces hydraulic power demands and improves efficiency. Oil filtration has also been enhanced throughout the hydraulic system for increased reliability and reduced maintenance.

How are they? Found a package deal for one. Has rebuilt motor and new feeder house chains. Looking to do about 100 acre corn if it's left over every year. Comes with a flex head, 960 20'. And a 6 row narrow 962 corn head. Seems like it's a had some use, just over 3000hrs. Anything to really look at? Never really been around combines much..

I don't know any specifics on the NH combines beyond them having a decent reputation. The Cat 3208 is a good engine at the lower HP it was rated in this application, keep it cool and it should last a long time.

Couple rules that apply to all combines. New or old, they are basically a big metal box filled with moving parts determined to destroy one another.... And one 10 Lb rock can turn a $100k combine into a $50k combine in less time than it takes to read this sentence.
