I run a 443 on a 6620 without many issues. I plant 6 and shell 4 but as long as you are pretty good planting it's not an issue. I have 24.5 X32 front tires on the combine and you need to fold the ladder up. It's a tight squeeze and can be an issue with down corn at times and also if the ground is really soft. There is just not a lot of extra room to the next standing row. A few pics for you to judge for yourself. If you go with the 6620 be sure to check out the Titan II wiki page for other helpful tips and modifications.
