Loewen AFX Front Rotor Kits
Loewen Helical Bar Concave HELICAL BAR
Small Grain Concave

The Helical Bar concave is often the solution when more aggressive threshing is needed. Since the cross bars and wires run diagonally in a helical bar concave, material entering the rotor strikes a helical bar concave at a right angle. This prevents whiteheads and unthreshed grain. This innovative concave can be installed in the front concave position when encountering tough threshing grain. If even more aggressive results are desired the middle concave can be replaced with a helical bar concave as well.

Loewen Round Bar Concave ROUND BAR
Corn & Bean Concave

The Round Bar concaves feature round cross bars and is void of wires. This differs from the square edged bars of the wide, narrow, and helical concaves. The round bar concave is a great fit to harvest field corn (even at levels above 25% moisture), soybeans, popcorn, and food corn. The round bar concave is also a suitable option for small grains, sorghum, sunflowers, and canola when used in conjunction with a helical bar concave in the front position.

Loewen Narrow Wire Concave NARROW WIRE
Canola, Wheat, Barley, Oat Concave

The Narrow Wire concaves are the standard choice for small grains such as canola, wheat, barley, oats as well as other cereal crops and fine seeds. Running perpendicular to the heavy-duty cross bars, the wires are spaced just wide enough to allow the small grain to fall through the concave while allowing the chaff to continue toward the rear of the combine. Narrow wire concaves are not recommended for use in corn

Loewen Wide Wire Concave WIDE WIRE
Corn & Bean Concave

The Wide Wire concaves are intended for corn (not reccomended above 25% moisture), soybeans and other large grain crops like rice, sorghum, and sunflowers. Similar to the narrow wire concave in overall design, the wide wire concave is equipped with wires perpendicular to the strong cross bars, but at a wider gap to allow more space for larger material to be threshed and for the larger grain to make its way down through the concave without plugging.
