Concaves that make a real
difference to your threshing.
Most harvesters now use a Rotary or Axial Flow threshing
cylinder design. This has increased tonnes per hour
dramatically in recent years.
A properly tuned harvester will thresh and separate
to a high standard.
Because clearances of rotor bars from concaves are
commonly greater than more conventional concaves
they are often regarded as not so critical.
But clearances are critical whenever threshing gets
hard and concaves have to be closed up. So we strongly
recommend rotor bars are shimmed to a uniform
clearance off the concaves so you are ready for tough
Harvestaire concaves are heavier than originals.
This reduces stretch and bowing (or opening up)
of concaves which means some areas of the concaves
are further away from the rotor bars than others.
