I run OEM Concaves. Why do I need a RC Thresh Modules Kit?

RC Modules are designed for those owners looking to gain efficiency & productivity, greater than OEM modules.
RC Modules are one part, but one of the most vital segments, of the "suite of tools" - to gain maximum efficiency of your machine.

RC modules are versatile, and work extremely well in a very wide range of Australian crops and conditions.

There's no need to change #1 modules for different cereal & pulse crops.
RC modules provide maximum threshing without "cutting up the straw". Cut-up straw will exit the rotor cage & overload the cleaning system.

RC module inserts are 304 stainless steel with 4140 road bars.

Inserts are reversible - all designed for longevity.

Rod Gribble has run a professional, contract harvesting business with vast experience in harvesting all sorts of grains in varying field & crop conditions for more than 30 years.
