Our 9650 Walker never had the beater grate curtain installed. This is the curtain that attaches to the bottom of the beater grate, then there are two more curtains further back above the walkers. How many of you run this curtain in small grains? To me it looks like it would really help keep more of the grain down on the sieve. It looks like a close fit in there, have any of you ever had issues with the curtain mounting bracket getting caught on the walker? There are holes in the bottom of the grate but I am not sure if they are the the right ones for the bracket, I know the hole size is too small for the bolts that came with the kit. If I have to mount the brackets and drill holes in the bottom of the grate it would probably be best just to take the whole grate out and do it outside the combine......right? Thanks for any advice.
