John Deere 6600 D combine

Do you have any idea what wheat heads I can use with this combine, length and model? thanks

914 P/U header I believe.

i have owned several 6600 nice machines, we had 212 pickup heads, 216 and 222 wheat cutting heads , and 220 flex for beans , really all of 200 series fit , and more question is can you handle the straw the big ones will bring in like 224 or even 230, , bill

thank you love2drive
