Well they do break down just like any other brand. We have a local dealer that is worthless. He parks a brand new Kubota out front and then tries to switch guys into his lesser brands like TYM and Century. He can make more money on the other brands. HE stocks a bare minimum of parts. I do mean a bare minimum.
Close friend has a M110. He has had some minor stuff go wrong but nothing major. We where servicing the tractor last summer in my shop. He went to get all the filters for the tractor. The local dealer did not have either the oil filter nor the hydraulic filter. My friend wanted OEM stuff so he had to drive 60 miles one way to the next dealer to get the needed filters.
He had a M8950 before the M110. At 6500 hours the pressure plate flew apart. It tore up the throw out fork and cross shaft. It was a loader tractor so that was not the issue. The fact that we had to wait six weeks for Kubota to get the parts here was an issue.
So like I said they are just another brand that has its own issues and dealers that are less than desirable. Just like the other brands have these issues too.
