I have a 2016 Kioti CS2210 with 120 hours on it which I use generally for mowing and snow blowing in the winter. I have performed all the manual-specified maintenance at the specified intervals including replacement of the fuel filter. While mowing yesterday morning i noticed that the mid-mount mower and rear PTO driven Protero grass catcher were bogging down without any apparent effect on engine RPM either by gauge or by ear. This wasn't a case of trying to mow too much too fast and there doesn't appear to be anything impeding the blades. Moreover, when I engage the PTO without load (e.g. on the pavement) both implements engage and sound completely normal but as soon as I apply load (e.g. begin cutting) I lose PTO rotation. I suspect this is the PTO clutch, but am shocked that this would happen after only 120 hours. I would appreciate any thoughts or recommendations. Could this be electrical? Is there a way to adjust the clutch or will this require the Dealer to take the rear end appart? Thanks in advance.
