"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…..no grinding like with the OEM parts.  When I traded for an S690 I tried Estes concaves to compare. They were hard to put in and it was difficult to get the machine set properly. I replaced the Estes 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." 

"When we first got our STS John Deere combines we couldn't believe the poor threshing results with the factory parts, so we called Kuchar, and had him convert our combines to Kuchar Parts . We immediately saw a better sample and easier threshing. It's also more cost effective because we do more threshing in less time! If Kuchar has something for your combine you'd better install it!"

"We first installed Kuchar Combine Parts in our JD 9860 STS in June, 2008. We found that we gained 20% capacity. The heavier rotor runs smoother than the factory models, we have less grain loss and I'm very impressed with the smoothness of threshing. It is money well spent!"

"We own a Deere 9750 STS. With Kuchar Concaves, we're getting a much cleaner sample in corn and soybeans. The machine handles tougher conditions better and is able to maintain full capacity. The concaves stay clean and haven't experienced any trash buildup like there was with the OEM concaves. We're very satisfied with the Kuchar concaves and the cleaner grain they produce."

"George, I wanted you to know how pleased we are with the John Deere Concaves we purchased from you.  We reduced field losses, improved the grain tank sample and the combine adjustments were quite simple. It’s a very good product!"

"I raise commercial corn and soybeans and harvest with a 5130 International combine with an 8 row corn head and a 25 foot platform. In the past few years I have had trouble cutting green stem beans. I want to use fungicide on my beans for better yields, but have only treated a few acres because they were so hard to harvest.  After I installed a set of Kuchar concaves in my 5130  I was able to cut green stem beans with green leaves still on them with NO trouble. The Kuchar concaves never plugged. I still had a clean sample and was able to run a mile an hour faster with less fuel consumption. I also harvested some green leaf corn with NO problems.  Next year I will treat all of my beans with fungicide."

"WOW is all I can say! I installed the Kuchar kit last fall and went to harvest and I couldn't believe the difference these parts made in my 9550 walker combine. I literally doubled my acres per day on beans from the previous year with the absolute cleanest sample I have ever had. My best day was 150 acres compared to 75 the previous year! I also saw an increase in productivity on corn as well with a very clean sample. Material seemed to flow through the machine extremely well. I am very impressed with Kuchar products!  Installing Kuchar parts was the best investment I have made on my farm to this day. I would definitely purchase again. I’m a customer for life. Thank you George."

"I purchased Kuchar Concaves for a Case IH 7088.  I am completely satisfied with the results:  More capacity, less rotor loss and a better sample in the tank compared to the OEM concaves."

"Our 9560 STS John Deere would not thresh grain out of the pods in tough conditions. We had to up the rotor speed to the point where it split the beans to get them out of the pods. We were going to change machines until we found out about Kuchar Combine Parts. I called George, told him the problems we were having and he recommended the parts that would fix our problems. Now we can pick beans in very wet conditions with no split beans and get a cleaner sample in the tank. There’s nothing on the ground and the machine pulled a lot easier in tough conditions! Without these parts we would have traded our combine for a different color."

"My partner, Scott Odie and I farm 4,000 acres; 1,700 soybeans and 2,300 acres of corn. We have always harvested with John Deere combines. This year the machine was an S680 with a 40 foot JD draper for beans and a 16R30 Drago corn head. I gutted a brand new machine and replaced the parts with George's high performance kit. We only logged 254.4 separating hours and 390.8 engine hours. Plus a higher quality of grain and more even flow through the machine, than I had ever encountered! If it wasn't for our local JD dealer and George, I would be looking for a different colored machine!  George’s parts are farmer approved!"

"I was having problems with grinding corn on my 9600 and thought it was my settings. After seeing the same problem at the Farm Progress Show, I knew the combine was the problem, not me. I installed George's Concave, Super Kit and Steel Curtains. These parts reduced the screenings and foreign material. The better action in the straw walkers means I'm leaving less grain in the field. It also takes less horsepower, and I can drive faster.”
