The more I research the more interested I am in purchasing a combine. I would like to start small (maybe smalller than the two listed) so that if things don't work out schedule wise I won't feel bad about letting it sit and having the custom harvesters do everything. If it does work out, I would consider cutting alongside them.

Anyways, for now, I was wondering what I could expect in terms of capacity (in corn with an 8 row head and wheat with a stripper header) for these two combines as well as maintenance costs. I would be running with a smaller graincart usually in 100 bushel corn but sometimes in 200 bushel corn (for the irrigated) so unloading auger speed and bin capacity is important too. I don't know where to get specifications for older combines so that's why I'm looking here.

The immediate advantage appears to be to the 8820 because of cost. In other posts that I have read, the 8820 is actually pretty close in capacity to a 9600 which I thought had more capacity than a 1680, but I really don't know numbers so any information you can provide would be appreciated. Thanks.
