Didnt meen to sound to definitive Ive had a lot of trouble to, in silver red and green machines none of them new though.Are you going to replace themIJ

 

[Chet]

Unless you harvest only corn I would bet you could never get 500 hrs out of a set of bars.We run 4 72s put 550-600 sep. hours per year, and they are shot.We have never since 1980 taken off the second year without new bars on. Chet

The area you are in must make a large difference. We have operators with bars that are like new at 1000 hours and seperator side twice that. The guys with a number of rocks may have them wore out in half the time or less. Have you been using the factory chromed barsIJ I think the guys are better off with a hardened bar or something other than chrome if they have rocks.

Would you ever consider giving me dealer name and S_N of machines. I would like to check out there take on the situation. I know there can be problems with any new machine whether they are proven design or come from new plant or whatever. Sounds to me you had way to much trouble but I'm sure much would be prevented with a better predelivery. I'll touch on a few things I pick from your list that could be prevented. I found out well before harvest that manufactor of spreader motors or pumps had missing snap ring. At least that is what I was told and if you were putting on new motors they likly had snap ring missing too. Number one reason I have ever found for broken clean grain or tailings auger is overtightened chain. I'm sure a very loose chain can do the same thing when it starts jumping teeth but most of the time I have found that I need to loosen chain way up to get connector back in. Mis-aligned idlers would be main reason for ripped belts. The idler pivot bolt or alignment nuts are main reason for idlers to come out of align. Idlers are normally lined up good from plant but I will often find hardware loose enough here or there that idler goes out of line with time. Feed chains should never give you that much trouble. Are feed strippers in place for crops other than corn. There is a chance that front and rear strippers are in place and they can cause feeding problems. Do you have rock sumpIJ They can give feeding problems in some conditions. We have been working on some thing to prevent feeding problems when rock sump is installed. Ideally I like rock door hump with third helical extended over top left of feeder opening. Replacing feed clutches and other things so early indicate a bad feeding problem. Did you find out what went wrong with engineIJ I have only had to align a couple gearbox since the P3's come out and they had ate a bunch of rocks or other hard objects. We loctite all setscrews in during predelivery especially setscrews on sprockets where a chain is involved. We have never broken a feed chain slat but have bent them bad from very hard object. You say hole wore threw next to rock sump. Did hole get punched threw from something very hard. It would be fun to know how that STS would of got along if he run with you guys this season. I believe you got most of the bugs out of your machines but it still should be gone back over with a good post delivery and feeding problem taken care of. What sort of heads are you feeding these machines withIJ We'll try help you out if interested.

We harvest from oklahoma to the Canadian line then back to Kansas for fall harvest. We have rocks in North Dakota but generaly bars are in bad shape before we get there. Have run Agco's Chrome- double chrome-Aces double chrome bars witch are nolonger available, Sunnybrooks chrome and their boronized bars with various thickneses.I have all 4 rotors on the floor in the shop now and the thrshers are all wore out.Seperator side will make 2 runs sometimes. We started running the extended bars on the discharge side of rotor in 93 to get the material to the discharge. Helped green material go through better but didn't prolong the wear. Chet

 

[Dan]

Have you got the third helical extended over top left corner of feeder yet or do you run steep pitch with any extra ones. How many reverse bars do you normally run and whereIJ I wish we would of caught onto the extended bars in '93 or earlier. Do you know who originated the extended bar ideaIJ Did you run P1s and what kind of life did you get out of them barsIJ

We ran 68 degree helicals for the company back several years ago, they done real well in wheat but when we ran in milo with green leaves it carried it out the rotor worse than it did with original eq. We run a reverse bar in each row and still have trouble with rotor loss in certain conditions. They are staggered 180 degrees apart. We have tried all kinds of configurations as everybody has. We ran the P1 with the little concave the first year before the return to cylinder was available, what a mess that was in Canada with Nepawa wheat. Put concave extensions in, set of 5 welded togeather l concave bars that were bolted to the door on the l. That cleaned the wheat but could ruin a set of bars quick. Then went to Sunnybrook 13 bar concaves, shimmed rotors to within 10,000ths and they done a cleaner job in wheat and milo than we can do now. Still running these gleanersnitzels but tired of same old problems. Planning on trading for 2 72s and 2 9750s at least will have new problems! Chet

Don't know how new your machines are or how long you've been watching this site but many simple cures to old problems are hear. Many many old problems have been taken care of but more could be done and is being done as fast as I can ever remember. HP has gone up, threwput has gone up, many crops are tougher, and with every action there is a reaction. Proto type and preproduction testing just doesn't always go to production without a snag here or there. There is no milo around hear but have heard that seperator grate cover helps when leaves are green. Maybe you have tried the hi-wide wire seperator grate. I think maybe the milo gets rolled into the leaves when rolling over seperator grate. I think some of the seeds may be getting caught in the green leafs at the thresher grate. We have made thresher grate less aggresive for edible beans, sunflowers, and canola by installing some thick filler plates. If I were in green milo and having a problem I would set up rotor with all forward bars and then fasten stationary rasp bar in seperator side. There are more and more P1s set up for flow mega flow and have some trouble holding some crops. Stationary rasp bar helped but what did more than anything is fastening in a couple of them old spikes strips that used to come with machines in early '80s. I would have machine set for mega flow before installing spikes for I hear they used to blow up cages with them old original helicals and reverse bars installed. I believe the spikes would open up the leaves and let traped crop out. Some guys have rigged knifes or pegs on P3s and results will be coming. We run into the hard to thresh wheat also before tailing return was available. We installed that concave extention and boy did that kill the machine. Every now and then I come across a new concave extention we still have in the bin and boy does that bring up memories. Flat iron helicals, concave extention, reverse bars equal dead machine. We've never installed a 13 bar concave but some have come into our area. About every one complain of rotor loss in some crops and conditions no matter how they set concave. It seems as though there are just to many crossbars for the not so aggresive P1 cylinder bar. I think the crop can start rolling there and if rotor is set up for mega flow the crop sometimes won't get out in time. So far at least two of these guys have installed a couple of the peg strips and it helped greatly. Hate to see you get a couple 9750's but would love to get a report next fall. Give us a call or leave a message sometime for we just may be able to help with old problems or at least try.

G'Day chet For milo I have heard that a couple of guy's around me had some Copper bars in a R72 to help with green material! It realy helped in barley, they also left them in for wheat,lentils and beans!! Might need to call in an ask about them at the local dealer!!! Tell them they are available down under!! through Massey ! Sorry I don't have the part No for you but I can look it up if you need some more info Rolf
