Ok, I'm a little confused here. Exactly what scenario while mowing causes the engine to shut down as long as you're siting normally in the seat? When I'm backing up with the mower running, I press and hold the rocker switch down, I continue mowing in reverse. If I release the rocker switch while pressure is still on the reverse peddle, mine just disengages the pto and the engine is still running. The only time my engine shuts down is when my butt gets light on the seat from leaning to far forward to see something. I have a 2018 1025r. Has something changed on either the older or newer models?
