The feeder house conveyor chain delivers crop material from the front end of the combine to the threshing area. A worn conveyor chain will not move material efficiently, causing a material flow problem. The results of a worn feeder house conveyor chain are:
-
Feeder house plugging
-
Chain jumping sprocket teeth
-
Excessive sprocket teeth wear
-
Slug feeding
-
Reduced ground speed
-
Higher losses
-
Premature threshing
-
Grain damage
Tension is the major cause of feeder house conveyor chain wear. It is normal for center strands to sag more because of the weight of the slat and the upward force of crop material. Shaft and bearing failures are also often caused by excessive chain tension.
Feeder house conveyor chain, with wide-spaced slats, is standard equipment for all 9000 Series Combines. The under-slot slat and chain conveyor system smoothly delivers material to the threshing area. Conveyor chain, with narrow-spaced slats, prevents corn, grain sorghum, or sunflower stalks from "hair-pinning", wrapping over the slats, wrapping on the drive shaft, or causing the chain to jump teeth on the drive sprockets.
The narrow-slat feeder house conveyor chain was standard equipment on all Titan Combines (PIN 60000 and up). The wide-spaced-slat feeder house conveyor chain is available as a service part only. It provides better material handling in crops such as small grain with short straw, and green material that can stick to the feeder house bottom.
Feed Accelerator
Single Tine Separator (STS) Combines incorporate a feed accelerator to move the crop material from the feeder house into the feed section of the STS module. The feed accelerator features a 10-wing design with three replaceable wear strips on each wing. The wear strips can be reversed once to extend the life of the strips.
Failure to reverse or replace worn feed accelerator strips can affect the combine's material handling performance, especially in tough, green-stemmed crops.
