Been getting my arse kicked by this tractor,

I have replaced the seat switched and neautral safety switch, still doesnt work. Tractor has 1400 hours on it, starts and runs absoluetly fine, but when trying to shift out of gear it cuts power to the fuel solenoid.

Running can move the clutch, no problem. If the NSS stays depressed it will shift into gear (removed to hold closed), and it will move. Replacing the shifter depressor and ball socket but ????

I am at a loss, i have also tested my new switch against another good used one and thats not it, checked PTO switches they are ok too.

As soon as its shifted out of neautral , u can hear the solenoiud click and it kills the fuel supply off. What else would cause this.

Thx much
