Okay, I own this one. I connected my PTO shaft for my brush hog type mower. I thought it latched but it didn't. After bringing the mower up to speed it slipped off the PTO drive. The mower continued to spin the shaft. It flew around wildly until the blade slowed and stopped. Of course the plastic shield was damaged but in thrashing around it seems to have put a dent into the PTO tube preventing smooth sliding in and out. A new PTO shaft would be in excess of $300 at the Kubota dealer. A local vendor sold me the inner and outer bare shafts for just over $100. Of course I'll have to do my own cutting and drilling. In the future I'll be more careful checking to ensure the PTO is locked into place. I may also rig some kind of sling to prevent the shaft from dropping and thrashing if it becomes disconnected.
