Re: old 8010 and new 8010 - how is bin different?
Ok, ok. I must apologize for giving you guys the wrong information the first time around. I read the info somewhere and it stuck in my brain. I did a little more research on this ISO specification thing, and we were totally off. I have no idea where the geometry thing came from, but that isnít correct. I removed all the posts with the incorrect information, so later on nobody reads bad info before scrolling down to see the correct info.
Grain tank capacity: The ISO spec is actually very simple and accurate. Basically it says that you need to fill the grain tank as you would normally (via the clean grain elevator) until grain starts to run over the sides. Then you unload that, and check the bushels that were unloaded. You have to do several tests and average them.
Unload capacity: Basically you need to have the whole machine running (header, rotor, etc). With a full grain tank, you start unloading and start a stop watch at the same time. You keep timing until the flow starts to slow down right before it is empty. Divide the bushels unloaded by the time it took. Of course you have to do this a few times and average the numbers.
The ISO spec isnít all that old, so Iíd guess that when the 8010 first came out, not a lot of time was spent on numbers. In this case, it is better to under estimate than over estimate. Nothing changed on the 8010ís grain tank size or unload rate, it just finally got an accurate test, and then probably took a while to update all the marketing materials.
Again, I apologize for giving anyone the wrong idea in my previous (now removed) post. I hate to see inaccurate information spread across the Internet. Bad information is worse than no information at all.
