I seen a thread on here that I thought might help but unhooking the battery over night did not help, I'm getting error code 20 and depress clutch on my side console readout and am having no luck starting the tractor, I've checked fuses as well as trying to jump it at the starter to no evail. Please help as the snow is deep haha need to plow. One more thing that I think caused it is I had accidentally hooked up the batter booster backwards, it did blow one of the 4 fuzes so I replaced Fuze and got the message again please help.
