Just replaced the JD small wire concaves in a 9760 with a set of Howard brand concaves made in Biggar, SK. Cannot believe it is the same machine. Was having trouble with unthreshed/ partially threshed heads in HRSW. Now I can run more clearance, slower rotor speed and get a clean sample. The company processed my order, built them (their inventory was sold out), and shipped them in 5 days. I would highly recommend them .

Just put in PFP concaves in my 9760 with bullit rotor. Same story. No filler bands, more clearance and a little slower rotor speed. Good sample, same ground speed with 5 more feet of header, and better quality straw dropped for baling. And in a very good hrs crop.
