[QUOTE="greybeard, post: 943779, member: 18945"] I worked as a tech (mechanic to us old schoolers) for a Kubota dealer 2007-2009, and they too had PTO shaft problems--mostly on their bigger M-series tractors. The bearing cages that held the PTO output section would break, causing complete failure of the PTO section. IIRC, all happened while pulling batwing mowers and all were covered under warranty, but gawd what a mess it makes when that bearing cage goes-lots of little tiny steel shards thru out the hydraulic fluid holding cavities. The only other significant and recurring problem I saw was a lot of loader cylinder failures--lift and tilt cylinders. Piston retaining nuts backing off the shafts and piston seals going south on almost new units, and we had a big pallet full of warranteed cylinders to ship back to Kubota. [u]BUT[/u], you know how it is when you work in any shop--you see all the failures every day, but don't have a perspective of how that balances out in comparison to the total numbers sold. I saw only one early engine failure while I was there--a piston pulled in 2 on an engine with less than 100 hrs on it--factory defective piston I suspect. It happens in any and all brands every once in a while. Perkins diesel=virtually bulletproof. I have one in an old Leyland that has just been a hoss of a tractor and engine. [/QUOTE]
