How much better is a Agco 500 or a 800 series flex head over a Duetz Allis 320? Thanks Dave

Day and night. You can get a 500 to work as well as a 800 but you can’t make a 300 match a 500.

The biggest difference between 300 and later series heads is the distance material has to travel from the knife to the table conveyor. My opinion, but an air bar goes a long way towards canceling any advantage a 500 has over a 300. To be perfectly frank, most any Gleaner flex platform really needs air in order to do an acceptable job in short, thin soys, edible beans, or any other crop that needs to be cut tight to the ground.

500 is far better than a 300. The 800 I have never cared for because it was almost back to what a 300 was for poor feeding in short soybeans. The 30 inch diameter auger (instead of 24 inch) moves the reel back forward 3 inches, therefore poorer feeding in some conditions. Every 800 I had I always made a slowdown sprocket for the auger because that huge diameter was tooooo fast at the same RPM's. You'd think an Engineer could have seen that coming.................

We have had a 500, 8000, and now a 8200. The 8000 and 8200 both sported an air reel. We now run a roller in the spring. The things that have helped us the most with feeding the crop in is the roller to smooth the ground and push down rocks and a Trimble 750 GPS. We combine our beans at a 25 degree angle. The greater the angle; the better they feed in. Don't laugh, this works and work great.

Thanks guys, I saw a good look,en 320 on line with a double cut knife & it looked like a raised SS floor, for quite a bit less coin than dealers are asking for a 520 so I thought I better ask. One more question, why do I see alot of gleaner heads advertized with a sch knife kit, what advantage does it have vs a stock knife ? Thanks Dave

The Schumacher doesn't require any shims or hold downs to keep it cutting clean. Just a lot less maintenance. The double cuts can do a fine job, but do require attention. Done right there's very little shatter loss. Some don't like the way they perform in wheat or green, grassy weeds, so I guess that's a consideration if you regularly shackle your flex head up to harvest wheat and such.
