Abstract: A grain conserving kit for combines. The invention includes a rigid, notched transfer plate which is interposed between a combine cylinder thresher and the straw walkers in replacement of the conventional fingers assembly. The reduced width finger replacement plate is located below the beater above the concave, and it allows an abundance of grain and fine chaff to fall off the rearward end thereof as the straw walkers oscillate. The plate cooperates with a vertically oriented, rigid baffle to establish a drop chute. Air confiner apparatus is adapted to be coupled about the combine grain cleaning structure and the straw walkers. The confiner apparatus redistributes air flow from the conventional air blower acting upon the combine sieve structure during the final grain cleaning process. By confining air flow, unwanted material accumulation upon the downhill side of the apparatus when operating at an incline is avoided. Additionally, proper air distribution prevents grain from being blown out with the chaff.
