Yanmar PTO Problem

Hi everyone. I have a Yanmar 186D and I have a problem getting the PTO to engage sometimes. The clutch works fine for the trator wheels but I often have to persuade the PTO to go in (double clutch it). It will also sound a series of tick, tick, ticks descending in frequency as the PTO spins down when I push in the clutch (especially if the implement is in the air, in this case, the tiller). The transmission oil is fine. Any ideas?

Thanks for the comment. Any idea what part of the PTO accomplishes this? I fear it is more than what you suggest because I have a hard time getting it into (PTO) gear - I have to double clutch. But it would be nice not to be concerned about the clicking - a momentum dissapating device - something to do with the overdrive clutch perhaps? ....
