TWIN ROTOR TECHNOLOGY<br />
New to the 2018 model is the Twin Pitch Plus rotor, built<br />
narrower but with the same 22-inch (55.9cm) overall diameter<br />
and slightly larger threshing elements.<br />
The combined turning radius of the two smaller rotors creates<br />
a tighter spiral pattern over the concave area, then widening out<br />
over the separation area – creating a ‘break’ in the flow pattern.<br />
This creates more centrifugal force than a large single rotor,<br />
separating the grain more quickly and reducing the crop mat –<br />
letting material flow easily through the machine while using up<br />
to 15 per cent less power.<br />
The auto concave reset is a handy upgrade. Previously, a shear<br />
bolt was located on the concave. If you got a little too ambitious,<br />
the shear bolt broke and it all turned to custard. Now, you simply<br />
reset from the cab, so no more half an hour of mucking around<br />
emptying the grain tank, etc. to get the shear bolt to line up.<br />
Also new on the harvester is its upgraded dynamic flow control<br />
system, allowing the operator to alter the rotor vanes and fan<br />
speed from the cab, in order to thresh better and blow lighter<br />
chaff and straw out of the sieve area quicker.<br />
The entire cleaning system – the grain pan, cleaning fan and<br />
sieves – remains level while the lower main frame moves up<br />
to a 15-degree pitch. With the ‘Opti-Fan’ automatic fan speed<br />
adjustment, this means less grain loss when going uphill and<br />
across slopes, making it no different to table-top paddocks.<br />
The unique Opti Clean feature of operating the grain pan and<br />
lower sieve together (opposing the pre- and upper-sieve motion)<br />
while the grain pan angle is elevated, enables 120 per cent<br />
greater cascade of material and allow for more air blast between<br />
the grain pan and the pre-sieve. These opposing movements are<br />
optimal for small grains, New Holland says, as well as reducing<br />
overall machine vibrations for greater operator comfort.<br />
DISCHARGE AND UNLOADING<br />
The New Holland has a 14.5 cubic metre tank grain tank with a<br />
fold-up lid that can be operated from the cab, and means the<br />
machine can be closed off at night.<br />
To deal with this extra throughput, augers are 25 per cent<br />
larger and the unloading rate is 142 litres per second – meaning<br />
the 8.3m unloading auger can empty the tank in less than two<br />
minutes, and then split fold at the rear of the unit to avoid<br />
collisions.<br />
Another smart feature is the movable chute tip that can also be<br />
controlled from the cab and allows trailers to be filled in a forage<br />
harvester-like fashion, which means less spillage.<br />
Opti-Spread has been upgraded in the 2018 model, with<br />
two spinning rotors and two adjustable deflectors to evenly<br />
distribute chaff or chopped straw across nearly 14 metres.<br />
VERDICT<br />
One question I had before the test drive was: how can the<br />
machine possibly need so much power? The answer is simple<br />
– capacity, and New Holland has created a clever way of<br />
harnessing that power and turning it into throughput.<br />
This is a very clever machine. Material is fed head-first<br />
into the feeder house and accelerated for positive transfer<br />
into the rotor by the DFR. The feeder is the same width<br />
as the rotors, so there is no narrowing of the crop causing<br />
it to slow. It then goes through the gentle yet quick Twin Pitch<br />
Plus rotors.<br />
Opti Clean takes care of the rest while the self-levelling<br />
system keeps things on track. The chaff and straw are<br />
chopped and spread all while you are sitting up front in<br />
the luxurious air-conditioned seat with 700hp behind you.<br />
What’s not to like?<br />
1. The 700hp New Holland CR10.90: First<br />
impressions are obvious – she’s a monster!<br />
2. The hydraulic tip on the end of the spout<br />
makes filling trailers easier<br />
3. The IntelliView IV touchscreen monitor<br />
4. The armrest controls are intuitive and will<br />
be familiar to those who operate New<br />
Holland tractors<br />
5. The concaves on the new twin pitch plus<br />
rotors<br />
6. Rear view of the twin rotor and sieve area<br />
7. The myriad of belts drive the various parts<br />
of the combine<br />

Minuses<br />
The diesel and AdBlue tanks are mounted high<br />
for refilling at the rear of the machine. This<br />
does, however, help with nearly 1.5 tonnes of<br />
weight as a rear ballast for heavy fronts.<br />
