What Others Say
"I installed a new concave from Sunnybrook Mfg. (Sunnybrook, Alberta, Canada) in my Deere 6601 combine and it's my best buy. The concave has more bars than the original one on the combine. It comes with four filler plates and virtually eliminates white caps, cracked grain, and loss over the walkers. It also has noticeably more capacity. It turned my 6601 into a real combine. It's truly a best buy."
