Concave & Separation Modules
#RC Thresh modules have been developed to make a flagship Case thresh properly to greatly reduce rotor loss, sieve loss & high returns. Bisalloy frames, stainless steel inserts, 4140 round bar. With well over 100 sets working in all cropping areas of Australia, users have commented just how affective they are in way more crops than I expected. “Installed them & just don’t take them out for all crops that I harvest”
RC Thresh Concaves
$4,850 + GST
Once you’ve measured & setup your machine correctly to OEM specifications, the “level & centre” of the module frame is so important in these machines. All sieves must be checked for even opening from front to back & side to side. Then calibrated. Pre-sieve is very important to be calibrated. Top Sieve Rear Curtains are a must fit.
RC Thresh concaves & RC Separation modules, along with the aforementioned, will greatly improve your flagship Case in capacity & efficiency.


RC Separation modules
$4,360 +GST (all new frames 2LH & 2 RH)
“Amazing difference these separation modules make to my machine”
“All but eliminated rotor loss”
Round bar doesn’t chop up straw.
Round bar makes crop material roll to greatly increase (grain) separation.
No wires where crop material can bridge & block up holes.
Use in any crop.
Made to last. Bisalloy plate & 4140 bar.

RC Separation grates S Series John Deere
$4,500 +GST (per set of 2. It’s all you need!)
John Deere S series machines are a very corn/soybean focused machine – because that’s what their biggest market is aimed at!
However, a “corn/soybean focus” has some shortfalls with setup in cereals grains, canola & rice. Rotor loss is a major detractor to overall performance.
Real world customer testing of RC Separation grates has proven these to be a major benefit to machine capacity & efficiency – in many types of crops & crop conditions.
“Turned this (S680) into a barley eating machine”
“Rotor loss is next to nothing”
Made to last. Bisalloy plate & 4140 bar.
Top Sieve Rear Curtains
$225 + GST + Freight
Top Sieve Rear Curtains fit under the rear section of the top sieve – off finger grate mountings – & hang forward. This makes air go through the sieves instead of finding the easiest path out the machine – usually between the top & bottom sieve – then out through the finger grate.
Sample & overall sieve capacity is markedly improved.
