JD 3300 in beans

FarmerZeb · Nov 5, 2012

i just ran my 3300 combine for the first time Saturday. I set everything by the book. I ended up with considerable debris in the grain tank (mostly bean pods). Manual says increase fan speed and if that doesn't work decrease the opening on the sieves. Adjusted both of these to no avail. I even took a hand held tach to the fan shaft and set the rpm that way. Still too much debris in the grain tank.

suggestions appreciated?

Speed up the cylinder and close the concave.

If they are green pods you may never get them out of the tank.

they are not green pods they are empty pod halves the combine in shelling nearly everything it takes in. the only issue is the debris

thanks for the suggestion

Close that Chaffer down until you see beans flying over the top of it. No real need to increase air flow unless chaff is piling on the Chaffer or sieve.

Beans are easy to clean. The 3300 should do good work. I hate a dirty sample. It's a pride thing. Embarrassing at the elevator....

Paul, I assume these pods have been threshed? If the air is as high as it will go you need to shut down the chaffer. One my Deere 4420 and 6620 the top seive (chaffer) is pretty much laying flat. The lower seive has smaller fingers so it can be open with a little angle. Go outside of the book settings some and that will clean things up. Even though the top seive is closed you can have the rear of it (tailings) open enough to catch any beans that might try to pass out of the back. A trick I use is to shut the top and bottom seives up. Then throw a handful of soybeans on each and adjust the levers open until the soybeans roll threw. That will keep the trash out.

Contrary to another post you CAN have the chaffer too tight in beans. I usually start setting the chaffer on any combine so my index finger will go in the opening, then give the shoe plenty of air. You may have to vary it a little to get the final sample you are after. You want the trash to float out the back of the combine, not just fall off the chaffer. If the chaffer is too tight the air flow will seemingly be "pressurized" with an effect similar to placing your thumb over a garden hose which will not clean the grain but will carry it over. You want air VOLUME, not pressure. Open the chaffer, increase the air, and the threshed pods should go away. Keep the trash floating off the shoe. Mike

In my experience Mike is dead on.I run my top screen on my Fords a little further open than normal and leave the fan wide open.I open my bottom screen just enough to let the beans fall through.If the J.D. has a screen extension on the rear that tilts up and down you want it laying flat down and just wide enough to let the beans fall through.

thank you all for the responses. i have only about 1/2 acre left to test on.

running an old combine is an art and i am at the finger paint level

You can always run them back through the combine to get the crap out. I did that on oats this year because I knew the horsey people wouldn't have been happy with them.

Are you getting docked at the elevator? Sometimes a sample can look really bad, but actually it's not bad enough to get docked. I was once told, haul as much junk in as you can without getting docked. Getting paid $15/bushel of empty hulls isn't that bad!!
