Why thousands of satisfied farmers have used our hardsurfaced concaves and cylinder bars
				We are aware that the concave is the most important part of the threshing operation in either conventional or rotary combines. Therefore, we take steps which provide for efficiency and longevity in machine operation.
								1. Concaves are harsurfaced in order to maintain square corners on the crossbars for operational life several times over that of OEM or others, and are machined in correct profile to ensure resistance against material flow is equal and precise throughout the entire threshing area.
							2. Concaves are reinforced and stress relieved. (Crossbars will not drop during machine operation).
						3. We offer "original spec." concaves, "perfect circle" concaves, and can do modifications required for specific areas or crops.
						4. Our concaves are generally priced at 50%---75% of OEM or others, with an operational life at least twice that of OEM or others.
						5. All models and types are available.
