And then there are stories like this from another Kubota TBN forum. You may pay your local dealer more for that expected great service and get this. Happens.........I purchased a new kubota Kommander zero-turn mower (ZG127E, 54 inch) in February 2014. The unit ran great the first spring/summer. I use it mainly for mowing the 2 acres around our house and for cutting along the fence lines on our 40 acres. The second season (2015) I began to experience a similar problem to you - that is after mowing for an hour to an hour and a half, the mower would begin to surge and slow down as if it wasn't getting a steady supply of fuel. Then, if you tried to stand up and step off the unit, the mower would just shut down (as if you hadn't set the safety brake). Then you would have to wait for some time before you could get it started again. The dealer I had purchased it from was no help (very poor service and parts group), so I finally trailered it to a more distant dealer in April of this year before the "mowing season" started. He diagnosed the problem as an engineering group flaw with the fuel switch/line coming out of the fuel tank. Apparently the opening is way too small so any debris or contaminant will cause a fuel flow problem. Additionally the brake switch was defective. The replacement of the brake switch (under warranty) solved that problem. Cleaning out the fuel line solved the other problem.
