Automatic fan speed adjustment on NH combine

Automatic fan speed adjustment to counter the effects of harvesting up and down hill makes its debut on the New Holland CX5090, the most powerful (295hp) of two five-walker combines, and two CX6000 (six-walker) machines.

OptiFan speed is set on level ground but automatically slows or speeds up to compensate for different sieve loading as the combine works up or down a slope.

It complements the SmartSieve system, which introduces an element of lateral movement to the sieves when harvesting across slopes.

The replacements for the CSX range have turret unloading augers giving 100-litre per second output – up from 72-litre/sec – and greater trailer clearance, and SCR-spec engines with better power delivery and improved economy.
