Kubota G1800 PTO - where's the PTO clutch?

[KubotaG1800]

Mowing along on the Kubota G1800 diesel and just when I'm almost finished the deck isn't cutting well. Leaving grass un-cut. Hmmmm, says I. I have checked all the springs and dimensions and they're within specs. The belts look new and are not slipping. The shaft and pulleys all turn when I move the deck belt. Nothing seems frozen or locked up. My question; Where is this elusive PTO clutch located? Thanks in advance for any help.

Thank you all for reading the mystery of the electric PTO clutch. The answer is apparently that the PTO clutch only exists on gas Kubotas. My G1800 is a diesel. The PTO wasn't engaging because the PTO belts were slipping ( sure didn't look like it to me at the time) and replacing them solved the problem. Thank you to all of you who took the time to read the post and puzzle over it with me.

Thank you for sharing. My thought was your PTO clutch went south or may need an adjustment, but glad to hear it was just the belt's slipping.
