Combines R 62 Question for the wheat guys

[Silver_Bullet]

When I went to no reverse bars I experience a little more rotor loss in some conditions but not enough to go back using reverse bars. I also have a Generation II Sunnybrook in mine which, by design, helps lower rotor loss some, anyway. I noticed this year that on the first day when the straw, (hard red winter wheat),was still a bit tough and moisture was over 13% that I had some rotor loss. The next day, when the straw was dry, rotor loss dissappeared. You might consider, using two reverse bars on the last row just to slow the movement of straw before being discharged if you are going to continue to be in tough conditions. Still, conditions have a lot to do with rotor loss.

We use a retarder system to preven loss as it takes less HP than reverse bars. We use a JD cyl bar with the rear edge trimmed off and bolt it into the separator grate bottom. We cut them into short about 2 foot sections so they can be installed through feed chain opening inside grain bin. We also use F2 concave bars bolted in for the same purpose.

What hyperizing have you doneIJ Hyperizing could include or exclude a whole host of things depending on year of machine ect. Is high idle correct for machine and can you pull machine down comfortably close to rated loadIJ loss will likely be less if machine is up to power and you fully load it. Are you getting a good thresh without closing down sieve to muchIJ Depending on your helical setup and if I was to try reduce loss with reverse bars I would try install just one bar in row A and one in row B. If I had steep pitch helicals on thresher side I would install one bar in row C and one in row D instead of A and B. Row A is next to discharge and D is next to gearbox. If you have a '97 or newer machine you can close down adjustable seperator grate a little at a time. Many guys seam to appreciate the results of stationary rasp bars. Other guys have installed the peg retarders from the old N series with results they like. There are only a few machines around hear with any form of retarders at all. I would like to try an old N series trick they used in corn if I should ever have a problem with loss. That is install short piece of helical straight fore and aft between the helicals. I would do this between the helicals on removable door and it should cause a certain amount of flipping of the straw. I'll give it a try sometime. If it is tough straw causing your loss you may want to look into what can cause it. If it is the straw not wanting to flow accross seperator grate which can rope it trapping seeds you can do a couple things: Replace grate with cage type material or install less aggresive high wide wire grate, install rotor with sweeps or equivalant design that will flow the tough straw accross grate without rolling. I better quit for this is getting a little long. Have a good day.
