I am looking for a 20-25 foot flex head for a R62. Are there many differences between the performance of the 300 and 500 series?

Also, what is a Trackback?

we had a 300 a 500 was better in short stem beans. never heard of trackback. 9250 dyna flex would be head of choice if you can cash flow it they will pay for there self in time with fuel savings and less machine wear. had a 8300 series I think, that I trade on the 9250 it was a decent head I think it was a 2006 if I remember right I got 18000 out of it.

What is your budget? A decent 300 let alone 500 series head are hard to come by. I would be looking for an 800 head if your budget is tight. The larger flighting of the 800/8000/8200 were a decent upgrade. As always newer is usually better in the 8xxx series of flexheads.

A 25' would be a better match than a 20' for an R62.

What are you running now on your R62?. Here's just my opinion, but I think adding an air bar to either a 300 or 500 head will make them about even and double the performance over stock. Like others have said finding either in excellent condition given their age might be a problem, so you might need to figure in an overhaul.

Most 300's have two piece feather sheets, that combined with greater depth from the knife to the conveyor make them a little more difficult to feed than a 500 series. Replacing them with one piece sheets makes them a little closer to "par" with the 500's (Thank you Amos!). This all relates to beans, in wheat, etc., I don't think it's such a big issue. Like I said, I think an air bar is the great equalizer.
