do you have a fine cut chopper installed in itIJ most of our combines with fine cut choppers do that

No Chopper, just spreader. How would a chopper cause thatIJ

you will have either an impeller, chopper or fine cut chopper in your combine. if you look up the chute above your spreader you will see it. the easiest way to see it is right behind the processor door there is a rectangular plate, take it off and you will see it. if it has single knives on it it is a regular chopper, if they are paired together it is a fine-cut, if it has blades held on by 1_2 inch carr. bolts it is an impeller. have not found what causes this build up, but it is on my list for this year.

Slim, You'll have to pardon my ignorance on these rotaries. We went from l-Series to this. We have an impeller. Is the only difference between and impeller, chopper, and fine-cut chopper changing out what is bolted onIJ I actually unbolted that plate last night before I got your email just to look inside of there. I looked at this further and it appears to me a weed or stick or something could get cross-ways above the dstribution augers and start that. Then the stick or weed could fall out, but the mass above it stay inplace and further compact and grow. I definatley see that we need to pull that door open at least once a day. It would be interesting if Gleaner would put a sensor paddle underneath the impeller below the screened area. You would then know how much grain isn't getting out until it gets to the impeller area. You could make finer adjustments based on that info. I'm sure there will always be "some" grain there, but you could set a basline and adjust from it. We are definately learning lots as we go. Here's another question for everyone: When welding on the machine do you disconnect the negative better cablesIJ What other measures can can you take if any to protect computers, PROM chips, etcIJ

going from impeller to a regular chopper all you need to switch is the chopper, grate, drive pulley (for 2 speeds),you will need to add an idler and the concave knife assembly sounds like a lot but it isn't to bad. a fine cut chopper requires a lot more work. everything from above along with some welding and drilling, the distribution augers have to be pulled out and shortened. along with some other piddly things.

I would strongly reccommend that you put an truck or heavy vechile type isolator switch into the battery lead negative cable. It makes for a quick isolation of the electrics and electronics if you want to do any welding or electrical maintenance work on the machine. Most importantly, it allows you to cut all electrical power to the machine in an emergency such as a short circuit or an electrical fire. The switch must be installed where it is readily accessible from outside the machine. We installed ours under the battery box area [ R62 ] and above the rear wheel where it can be readily reached. A bad fright caused by a fuel pump solenoid fire on the front of the Cummins taught us to be ready for any similar happening. Fortunately, in the end, the only damage suffered was a solenoid and some staining of the underwear. Cheers!

I would say it would be very very rare to have blockage like you explain. I only know of one machine that a guy was have lots of trouble with this. This machine was bought second hand and had a lot of hours. It was unsure which crops it had been in but the flighting on distribution augers was worn down dramatically. If you should find this to be persisting problem I would check the flighting. Also you need to check condition of helicals and cylinder bars for they are responsible for moving straw to discharge before it gets overly ground up. Also make sure cylinder bars go all the way to area ahead of discharge. I don't believe long cylinder bars were standard yet in '01 so you need to check. How many reverse cylinder bars do they have installedIJ There are some more hyper mods that will take straw all the way to discharge in one piece. You best measure how tall the helicals are and how the rest of cylinder is setup and then maybe address some hyper mods. Good luck

a 2001 machine should have factory extended bars on it. it sounds like that it what it has on it. the easiest way to tell is count how many bolts are holding the last bar on if it has 3 it is not an extended bar if it has 4 it is.

If you are seeing this problem and it is unique to machines with fine cut you will likely have to build shield to guide straw by the inset distribution auger bearing holder. Straw could likely start bridging there. I remember the 1st R50s needed the auger extended closer to bearing for bridging could occur.
