Combines Cracking field peas

Take a look at your clean grain auger and your bin fill auger. I took a brand new machine and cut both down about 5_16 inch and then chromed them to reduce crack in peas and garbs. Kinda hurts to take a torch to a new auger. Keep back of concave close and force the peas through the front part of the concave.

Is there any rumbling in rotor and listen when bin is emptyIJ Might need shimmed seperator side also if grumbling. But before worrying about shimming more helicals close the concave down to 1_8" to 1_4". In all reality that will likely give you 3_16" to 3_8" clearance which is allways better for edible beans. To large of concave clearance will allow crop to roll and grumble which will crack bean as well as peas I'm sure. If still cracking and no grumble than slow up rotor beyond 300RPM. Next step after flowing straw properly threw cage is accelerator rolls. We would pull paddles off rear accelerator roll for the N6 era machines for edible beans when the moisture was likely to be below 13ish percent. Then check clean grain augers per Dave's instructions to be sure they are not pinching between flighting and trough. Remember close concave clearance and fast enough cylinder speed to prevent grumble but not so fast that you are splitting peas.

Yes I do have some rumble going on. I thought I would really smash those peas if I closed the concave more. With removing paddles off rear accelerator do the peas get thrown down hard onto the grain pan and crack or do they get crushed in between the rollersIJ It's supposed to rain for a week up here so I won't be able to put your advise to work for a bit. I see in hyperizing you pull every other wire out of concave. Is that mainly for cornIJ If I do that will I have trouble thrashing in durumIJ We grow peas, lentils, canola, barley, winter wheat, and durum. Thanks for the help guys.

To close can damage seeds but closer will keep the suction going on and prevent rolling. If you allow them crops to start rolling at convave you likely won't get it stopped until it is out the spreader. It's not the clearance between the rolls but the velocity it gets thrown down. If it was easier to do I would suggest slowing the rolls by 20% because this will mostly fix it in very dry beans. Removing half the paddles gets close to duplicating what Gleaner had in the C62. I'd only think about doing anything with the rolls in peas after getting rid of grumbling. Don't know of anyone that had to remove rolls in any crop other than edible beans. Removing wires from concave is mainly to help prevent plugging in corn but I have not seen where it hurts us in any other crop as long as cylinder is set up to flow straw hyper style. Filler bars are needed in concave weather high wide wire or low narrow wire if in tough to knock out crops. You might be able to catch them peas with a little more moisture after the wet spell ends but you still will want to adjust to get rid of the grumbling. Best of luck

Hey Krawler - I feel your pain. In my experience some varieties of peas just crack easily - especially when they are really dry. Are you able to make time and keep the combine full or is this one of those fields where the crop mass is about 2 inches high, the mole hills are 4 inches high and the green chickweed slows you down to the point where getting 30 acres done is a successful dayIJ On my R70 it makes a huge difference in sample quality if we can make the combine work. On those days when we are lucky enough to get into some good conditions, we stuff 30 feet of peas into the rotor at about 4.5 mph and the cracking virtually disappears. The old Air Diesel roars, the Gleaner purrs and I smile. life is good.

I was able to cut at 4 mph the first day, but yes cutting right on ground. Second day was high humidity so I was slowed to 3 mph max vines were tough seeds were dry. Cracking was so bad I prob should have left it alone. I do notice she does a better job when she's running full.

We finally were able to get back in the field. Tightened up that concave and we did alot better job. I still had rumbling, tried tightening concave more but started to split again. Ground was wet and crop was laying on it so we didn't have close to ideal conditions. Thanks for the help guys, this is a great site.
