Replacement Concave Best Buys
![]() |
“We’ve been growing a lot of seed beans and are now getting into food-grade beans, so we wanted to see if these concaves would give us cleaner, higher-quality beans with less seed grinding.”
“George explained that the concaves would give us better performance in tough conditions where the stems are green. We’ve been getting the seed knocked out very well in those conditions. In more ideal conditions, we’re definitely seeing better-quality seed than with our previous concaves.
“When George was helping us install the concaves, he probably got six or more calls from customers asking various questions. He stopped what he was doing with us and answered every one of those people to make sure they were getting personal service and answers to their questions. He called me after we were running to ask how things were going. I appreciated that very much; that’s someone I can trust.”
Dennis Johnson, Pipestone, Minn.: “I put Kuchar concaves and rotor parts in my 9870 several years ago and got 20 to 30% more capacity, less grain on the ground, and cleaner grain in the tank, with no grinding like with the OEM parts.
“When I traded for an S690, I tried BrandX concaves for comparison. They were hard to put in, and it was difficult to set the machine properly. I replaced the parts with Kuchar’s, which were easier to install and worked much better. I had more capacity, cleaner grain and more in the tank. Kuchar parts definitely helped the machine harvest more efficiently and put more money in my pocket.”
