2005 L3830 won't start, HST on display

[WHATAMANUVA]

Driving over rough terrain my 2005 L3830 just quit, towed it home and checked the throttle safety switch, it's good, checked all fuses, good, when the key is turned I have all lights but it says HST on the display like I have my foot on the pedal. I can hear the relays behind the instrument cluster when I turn the key as well. First time it's ever quit on me in 16 yrs, any help much appreciated, Im behind on my firewood! Thanks again

If your tractor moves forward or back with a treadle be sure it's not sticking in one position - forward or reverse. Your switch may be good but the treadle has to be in a centered or neutral position. Sometimes it needs lube and sometimes something is jammed in it.
