A 35' head would be best, however 30' is as big as you can get. We run a 30' on our 72 and are trying to always get a better cut so we can keep the machine full. 5mph is a reasonable speed to keep the machine full, but the sickle performance is pretty poor. We ran 4-4.5 last year and have bought an SCHsickle for 2002 in hopes it will allow us to move the ground speed up, especially in no-till.
