My Kioti has a linked pedal function. But when using linked pedal, the DPF clogs up faster and the tractor spent most of its time warming up to operating temperature, running rich. The tractor also lost power as the exhaust filter clogs up. Since I was sold on the idea that regeneration cycles would only happen every fifty hours, and my way of using was regeneration cycles every 12 or so hours, I installed a warmer thermostat. Now with over 50 hours since my last manual regeneration cycle, I haven't lost power and the tractor has performed flawlessly. I'm very pleased with the result. Over on the My NX6010 thread, I documented my methodology to find and fit a warmer thermostat.
