having trouble with my sickle cutting cleanly and was wondering what the upper limit of the shaft speed is on a 930. i have a new sickle in and its just not cutting good at all. my wires have been pulled loose on the shaft sensor for the header so i really dont know how fast its currently turning. in the morning im going to get it fixed so see how fast its turning. the wheat ive been in lately is really light yielding and i want to move on faster, but just cannt get it cut off.
