45 HST won't start

[Barj]

Just going online to see if anyone can help me. I was in the middle of blowing snow when my knee hit the key which turned off the tractor. No big deal it happens all the time but this time it won't start. I should say, it won't allow it to turn over. Everything lights up in the dash but when I turn the key to start, nothing. At first the tractor was stuck in M range but depressing the brake allowed me to get it out. I was experimenting with the cruise control at the time and no matter where I switch it's toggle to it remains lit up in the dash. Also, normally there is an indicator in the dash of where you are in your range settings (H,M,L,N) but they're all lit up now.

I know some safety override is not allowing the tractor to start. I suspect it has something to do with the cruise (?). Help.

Is the pto still engaged? There may be a safety switch.

Yes the PTO is off.

Clutch safety switch, most likely. That is the only safety
switch my CK30 has, I am fairly sure. If you are pushing it
and no dice, maybe dirt in the contact? I dont know if the
new CK has other safeties. Gonna ask at the show next week.

It's HST. Does it have a safety clutch switch?

My CK30HST does. It's about a two year old model. Maybe snow in the switch somehow?

Where is the switch?

Looking in my workshop manual, the diagram indicates that the safety switch is located directly behind the clutch pedal above the floor. It is not beneath the floor as I thought it might have been so it would be improbable that snow somehow was packed in there creating a problem. Sorry for misguiding you on that.

When the clutch pedal is depressed it engages the safety switch allowing the engine to crank. So if the key turns all the way, the panel lights up and yet the engine will not crank it would seem that it has to be in that circuit someplace. I also know that there is a relay that clicks when I start mine, hopefully someone else here knows how that interface works.

trying to remember from service school, but the dk45 hst doesn't have a clutch so no switch. Might try disconnecting the battery for a bit.... the new hst's have a brain box.... we haven't got our load in yet so i haven't been able to play with one...

Make sure the ranger selector is in the neutral position.
