Cut beans yesterday and 1st time using new to me a 500 series 20ft head on a R50. this head is a SCH setup with a new sickle and guards look great. It left a ragged cut and would like to cut lower. By lower I mean the feather sheets need to be flatter. It cuts the stalk low enough. #1 looks like the guards are slightly pointed up. what is the recommended tilt. I don't have any rocks. #2 Read the adjustments in the book for down pressure on skid plates and my springs are roughly 2 5/8". The ground is very soft and I never pushed any dirt once or leave marks. I'm thinking it could have more down pressure. #3. I'm running in the low position and my old 300 head would go lower, problem is beans are sitting on the feather sheets and i have to power down to feed better. Reel is about as low as I want to go as will almost get into guards when I power it down. I feel it needs to go down about an inch to flatten out better. I haven't check the deminsion of the rod to the the 3 springs on the header height control. Do you shorten or lengthen a tad to go lower. Otherwise it floats great across the head. Also beans stems were tough which was probably most of the problem, but got a little time to tweak. Thanks Greg

Greg, if it's cutting ragged, check to see is you have the proper drive sheave for an SCH knife. It should take a larger sheave to turn the wobble box faster. I think the smallest was 213mm for the clean cut knife and the next size was 250mm for the standard knife. I think your going to want the 250mm or one a bit larger for the SCH. I believe you want to drive the SCH at @500-525rpm. If you've got the 213mm on now then the rpm is @418rpm, and that's too slow unless you creep through the field.

Didn't know that. I'll check. To measure, guessing you'd measure outside diameter or is it stamped on there. To double check, this would be the drive puller on the oppsite side of the wobble box pully (the one that drives the belt to turn wobble box) . Looking at the header book and shows RPM's similliar to what you said for the different systems. Thanks Greg

Yep, OD of the sheave. And it's the one that drives the WB sheave, should also have the sprocket for the header conveyor bolted to it (4 bolts). BTW, took me most of last years harvest to figure it out. A lot of heads came set up for the quick-cut/double cut knife, and when you switch to a standard or SCH knife it looks like it's moving in slow motion. Most dealers I've talked to don't even know they have different size sheaves available! No wonder some guy's hate the SCH when they switch to it. Also, you should be able to tilt your bar down quite a ways as the SCH just naturally cuts a little higher than the other systems. I guess that's why some went to the extreme of flipping the guards up side down and such to get a little closer. I've never seen it, so I can't say how it's done, but last year I was ready to try anything to make this outfit work like I wanted.

Thanks, read on flipping it also. I thought for the most part it cut fairly close to the ground. I think the head itself actuates up too soon. It needs more down pressure to flatten out. The reel was a good foot away from the cycle. I lowered down to the bottom pin hole. It feed a little better but still bunched up on right side of head. My 300 was the same but not as bad. It ran a little flatter and i would run in the mid position otherwise it would push dirt pretty bad. Most of it just needs a few more day to get the stems drier. I can see that lateral tilt would be the cats meow, but going to be a few years before that series gets into my price range. Raining pretty good today so may need less pressure now as it is going to be good and wet out.

I run a 320 flex on my R-50/AWS wind reel, and that sure helps even out the feeding and bunching. I put the one piece feather sheets on before wheat harvest, and I'm hoping to see how well it works. We're a good two weeks from starting soys here. Suppose I'd need to upgrade from the R-50 to be able to use a head with lateral tilt, and that's going to be a very long time from now I'm sure!

If you do not have air reel and have short enough beans to have bunching at cutter bar on one side only the head is not level with machine. You see the reel is going to stay level with the header and the cutter bar is hugging the ground. With this the reel will not have same distance from cutterbar all day thus not staying clean on the one side. Just an inch makes a big differance in some conditions if running just a standad reel. Get head leveled and then if equally as good or bad side to side you need to check into hose behind cutterbar or belting on reel to help bat it in.

Thanks, level looks good. Probably just need a few more days to dry the stems down and that'll probably help more than anything. We got a good soaking rain the last few days and going to be a while before we can get going again. South of us around Lincoln, Ne got 6 plus inches. Not a good time of year for that kind of moisture.
