Gleaner K Cracking Soybeans

cydectin · Oct 18, 2017

Getting lots of cracks. Cylinder on middle sheave as slow as it will go which is 590 rpm. Concave wide open with bars at 1,3, and 5. Beans are not coming back up return. Sample is clean but excessive splits. Options are put corn sheave on to get less cylinder speed or take #5 bar out. Cut beans yesterday that are running same moisture and they looked very good. They are a different variety. What is the consensus? Moisture is around 11% and I think elevator starts docking over 5% cracks. I have way more than 5%.

Slow it down.

Thanks for the reply Bob. I forgot to add that concave bars are the C-chanel style. I have it written in book that speed cracks. Beans are threshing almost to easy and stalks are greener than a gourd. Think in the morning I will switch to corn sheave and play with that speed range. Hate to as the slower the cylinder speed the more the machine has that woomping sound due to lack of cylinder speed. Most of the problem is these old machines were not made for these tougher beans stalks and higher yields. Old machine has served me very well.

Slow the cylinder down. Raise the cyl a tad. How many concave bars do you have in. Gleaner has very well written manuals i suggest you get one

Are you running channel concave bars or half rounds, rounds are easier on the crop.

cydectin · Oct 18, 2017

C-channel bars.

cydectin · Oct 18, 2017

Cylinder as slow as she will go with middle sized cylinder sheave. C-channel bars at 1,3, and 5. Cylinder to concave bars wide open and level.

WHAT IN THE WORLD DO YOU MEAN BY "CONCAVES WIDE OPEN"??

cornerpost · Oct 18, 2017

You say sample is clean. IF top and or bottom sieve to tight will over load return and vastly increase splits. They ha 've to look bad before dock for trash sets in.

cornerpost · Oct 18, 2017

Forgot to add if you have beans sticking sieves too far shut.

cydectin · Oct 18, 2017

I mean cylinder is raised as high as will go from threshing bars on rock door.

cydectin · Oct 18, 2017

If sieve is to tight I would be seeing whole beans coming up return. Not seeing that at all.

Remove bars 3 and 5

JD Seller · Oct 18, 2017

You need to remove the c-channel bars and put the half rounds in. This is how it was designed to run. Now I do not know how the half rounds will work in green stem beans.

Dad and combine ace friend of his always said speed is the big cracker of dry soybeans. Speed as in cylinder rpm

590 rpm is the upper limit for soys through a Gleaner. As others have said, slow it down to under 500, and use the half moon bars, set at half inch.... reduce cylinder clearance to get the sample and throughput you like,. Dry beans like your with green stems are always a challenge. Keep the engine rpm at rated speed minimum. Ben

When you slow cylinder down close up to 1/2" close a little more if whomping.
