Be careful when two people are working on a hay cutter, no matter if it is a disc cutter or sickle cutter. The cutting edges on these blades are supersharp, and if someone is working on the cutting area, make sure the other person does not turn any other part of the machine. Turning the driveline to grease a cross or CV (constant velocity) joint is a common practice. Be aware that when turning the driveline, you may also turn the discs or move the sickle.
