 Topic: F,M,L Straw Walker ??
Posted: 10 Apr 2020 at 5:09pm |
I have been driving past a M2 that's sitting along a fence row. The more I look at it, it sure looks like the walker area is "roughly" the same width as our F2, the housing is WAY longer. Do the larger machines have more walkers? Seems like a K series only had 3 walkers, but didn't know if each successive model added more walkers  . Thanks

F and M had 4 but each were different width and or length. L had 5 and are different width than M.

On a side note, what % 'age of cleaning is done with the walkers, or does ALL of the grain end up on them ??

Depends a lot on the crop, amount of materials going through combine and speed of operation. MACK

In the case of a 7700 Deere it's about 10% on the ground

Correct me if need be, but isn't grain loss over the walkers is pretty hard with a Gleaner, due to the 3 stage separation (on the L&M, 2-stage on everything else)...at the cylinder, then the separator raddle, then the walkers...by the time it gets to the walkers, a lot has already been separated out.

The sidehill MH Gleaners I put up pictures of a week or 2 back (or 3???) all had the Allis grain loss monitors. For calibration you could turn off chaffer or walkers. In the crops we cut (barley,safflower,and oats) 90 % of the time loss was the chaffer rather than walkers.
With climate being dry crops did not grow a large amount of straw. As well a harvest time being hot and dry,I am sure this had a big affect on how crops flowed in the separator. So other conditions may have had different out comes.
I thought I had heard or read the L and M where the same separator,just one straw walker width wider on a L. Any truth to this?

In 200bu corn I can carry kernels out the walkers (F2 4-30's). That's running over 3.5mph. Too many shucks to sift it through.

Yes sir. Most everything is the same, which is why some people say the M series is a more durable machine...same size shafts/sprockets/bearings/etc, but in a 1 straw walker narrower package

I don't think you get much walker loss, an old timer told me once if it gets to the walker it is gone. I am sure that is not 100% true.

Depending on crop and/or conditions, each straw walker can be adjusted forward or rearward.
Moved forward, the walker can grab more crop residue from raddle.
Moved rearward, the walker grabs less crop residue from raddle chain.
But usually , if grain is moving into walkers, it probably hasn’t been threshed properly at cylinder or walkers are too far forward. If threshing is proper, but walkers are too near raddle, then the grain filled residue isn’t allowed enough fan air to float straw/shucks between raddle & walkers, letting grain fall thru to cleaning shoe/chaffer.

Sadly, my original question was HOW MUCH crop/grain got thrown onto the walkers of ANY walker GLEANER  .Not sure where you guys are coming up with "walker/chaffer" loss  . This wasn't my intention at all .Mack made an observation though, I will narrow down my question to soybeans and corn crops, yields/ground speeds are "undetermined"  |

I guess I started that. Sorry. From my experience, when I discuss separation and cleaning amongst my farmer friends, loss is right there with it, so I guess that's why I subconsciously took it down that path.

That is nearly impossible to answer. It depends on crop condition, operator settings, speed and without taking a camera and watching it myself and then deciphering what I'm looking at..... to get a percentage...... from my prospective..... no can do and it would be only a guess on my part. That said I'd say in corn or soybeans there would be a lot less grain on the walkers vs small grains. That's the best I can do.
