Combines R72 vs 9650 STS

[Kelly]

I think that putting in a high wire grate on both the thresher and separator side would stop most of your rotor loss problems and make it perform much better than it did in the corn and millet and no adverse effects in wheat. You could modify your separator grate to open it up rather than put a new one in.

curly: The four reverse bars you have in the rotor will make a full size smaller machine out of your R72 from what it could be. Please do not make any judgement about what brand of combine your mext machine will be until you finish improvements to your machine as disclosed on this talk show site. (And these are inexpensive changes). You do yourself an injustice if you do. My $.02 from my experience.

Just an observation. How do you know if the sts is putting anything out the back when everything is ran through the chopperIJ I think this is a good question.

 

[roadfarmer]

not all sts's have a chopper. How do you know the R72 is putting any thing out the back if its ran though a chopperIJ

On STS you can raise spreader out of the way. We lay trays on ground to measure loss at header and out the back end.

roadfarmer: The spinner spreader will propell seed in trash far out, even into next uncut bean swath to see. So this makes it easy to see loss with the straw versus shoe loss which can be observed right behind the machine. The "buttoned up" rear of the STS makes this easy investigation of loss origin difficult, in my view. I really like to easily see and visually confirm the shoe condition and setting. As an example, local dealer brought out 9650STS to do bean combining demo fall of 2000, and had trouble getting pods out and sample cleaned up. Was adjusting and couldn't figure out why. later they discovered that the linkage to the outside sieve adjuster was missing a nut and wasn't doing anything(sieve wide open). I want to see and verify what is what!

 

[roadfarmer]

Oh, I see your point you want to be able to drive beside your pickup and here the beans hitting itIJ

 

[RamRod]

roadfarmer: Yes, but we don't need to be in a pickup to have this confirmation of low rotor loss. I have had many years with conventional machines, and as conditions change constantly through the day and again into night, I would often be out checking straw to see if all was getting all knocked out. This wastes time and reduces what is done in a day, and therefore this easy confirmation of a good job is very valuable. In soybeans, we always pick up on the go, and having total confidence in the job from the seat has allowed non stop bean cutting for as long as nature allows between stops. With the buttoned up back end of the STS, I am not sure how I would have that same confidence in the job.

 

[roadfarmer]

one other question. why do you guys always compare a class 7 gleaner to sombody's class 6 combineIJ

 

[RamRod]

roadfarmer: I agree that isn't a fair comparison in terms of design capacities. In another way, I think it is a fair comparison in that I believe I can own an R72 for same or less cost than owning a 9650STS, therefore making some sense in comparing that way. That is my experience in my combine market area.
