Combines Greenstar IJIJIJIJ

I know a farmer who has a 9510 who has had the greenstar, tried it then took it out and put in an ag leader. He told me (as I was riding around in the combine with him) that it was much more user freindly than the greenstar and that he much preferred the ag leader. I don't see how one can do you a lot of good unless you do a slug of custom work. They are real expensive. Good luck! GS

go with Agleader. If u ever trade combines to another brand, u can take the Agleader with ya. An Agleader can do anything a greenstar can and more. Agleaders are also easyer to tranfer from tracotr to combine to 4-wheeler to anything. Agleader is made to work in anything thought possible where a greenstar is made to work in deere and only deere for the most part.

Thank You for you response I didn't know that AG leader could do everything the greenstar could. As long as it will do everything the greenstar will it sounds like a better unit do you or anyone you know priced out the two units to see which one is cheaper or are they both completivly priced!!!

We ran four greenstars last year and found they didn't work for the most part. The moisture and yields were totally off. In corn we got a little estimate or ball park figure out of it. But that was only because we had a very experienced operator on one machine who knew how his greenstar used to act. We had a scale wagon along in corn ones and calibrated one unit completely. After we moved to the next field, it was far off again. Far off means like 30 to 50% in yields. A friend of ours runs seven units and experiences the same. If you want to do yield mapping you would have to find some real accurat measuring devices first. They need to be able to calibrate and check themselves. The unit should tell you in clear and simple English, when it detects a problem. Or do you want to translate error codes all the timeIJ After that you might get true numbers in row crops. But what if you cut with a platform headerIJ Can you cut the same width precisely all day longIJ When you told the unit you're cutting 30 feet and you're cutting only 27 you're making a 10% mistake to begin with. What about terrasesIJThe unit will add its own mistakes after that. How far off will you be after you have the whole field cutIJ I think all the yield mapping is no good until the computer is able to detect the cutting width at any time and figure it into the process. If you have really been lucky and got a true yield map after all, you still don't know exactly where your yield variation comes from. Is it because of the different soil, what everybody tells youIJ Is it because of differences in fertilizingIJ Is it the planterIJ Did somebody make a spraying mistakeIJ Did the pestizide from the neighbour drift in one dayIJ Did a hail storm hit the east side of the fieldIJ Did a hot wind dry out the south west side of the field moreIJ You could probably come up with some more questions. I have a question, too. Where can a person save or make that extra money what this yield mapping costsIJ

They guys runnin green star in my area feel they do a very accurate job mapping when set up right and calibrated. They are usally within 5% of the elevator tickets for the feild. The locals with ag leader do say they are a bit easer to use. But I like that you can use the green star component parts to do map based varible rate seeding, parrallel tracking ( no markers for seeding). Have you seen the auto track ( you only have to steer on the end of the feild),for the T seriesIJ it uses all the same components.

You can get parrallel tracking with agleader. It is one of the better ones because it goes by the last pass u you made, It doesn base everything off teh first pass. I don't know how greenstar is done. We have had no problem with varible rating with our agleader. And we recored all our planting this year. All you need for an agleader to do varyable rating is a raven monitor and a labtop makes it or handheld computer makes it easyer and more accurate. I u need that too on greenstar to do it right. I don't see how you save on componets. But if it works for u, keep doin it

I've had a little experience with both systems, and I would recommend the Ag leader system. Buy a 3000, and you can use it as your yield monitor, and as a controller for any other precision ag function. Greenstar is only accurate if you run a calibration on it every time there is a significant change in conditions (temperature, humidity, grain moisture). On the Ag leader, you use more than one calibration load, and you are supposed to combine each of these loads under varying conditions (change speed, change cutting width, change crop condition if possible). By doing this, it allows you to compensate for the various conditions that you'll operate under, and you only have to complete the calibration once. Also, if you get halfway through harvest and realize that you have done a calibration, you can go ahead and run your calibration loads and it will correct all of the data that you've already collected. It is next to impossible to do this with Greenstar, and the results aren't very good because you still have to base everything off of a single load.

I would go with ag leader, if calibrated corectly u can get it with in 1 to 2% of scale weight.Anything over 2%is not acurate enough for exaple 5% of 10,000 bu. is 500 bu. where do those extra bu. belong on that map. The ag leader is much sipler to operate than greenstar.

As I have gatthered from all the responsed AG leader is the way to go it is simple to use and more accurate so does anyone know how much it cost for the complete system and also for the use of the Satellite Thanks in advance.

According to last fall's list prices, you can get a complete PF3000 for $4190. I know that there was a 5% price increase for this year, but your dealer may be willing to haggle on the price a little. You've got several options on GPS. If you are just going to do yield mapping with your GPS, pick up a WAAS reciever. There won't be any subscription fees, and it's accurate enough for yield maps. Ag leader sells one for around $1200, but there are some cheaper options out there as well.
