I have a new BX23s with a seat safety switch that has turned out to be a major problem (with the seat in the far forward position the engine cuts out ALL THE TIME). How has Kubota gotten away with a design that creates a total loss of power in a vehicle that is loaded and moving? The black switch in the background of the plunger type is obviously a seat movement activated switch, but what is the gray switch in the foreground and what does it do? Love the tractor, but the seat safety switch function is decidedly unsafe. Thanks for your input.
