DK45SE HST won't start

Claude88 · Jul 18, 2012

My DK45SE HST won't start .
the first sign of trouble was a few weeks ago when it didn't start and i moved the range lever to high and back tolow then it started. then a week ago it needed many changes of the range lever to then finally start.
Now it doesn't start at all.
It has 104 hours, all manitenance done, full of fuel, battery fully charged. oil marking 2/3 on the dipstick full range.
Any body else that may of had this problem.

I assume you mean it won't crank, not that it won't start. (big difference) I assume all the normal lamps on the dash are lit. (goes thru glow cycle, but the Neutral lamp is not lit? And I assume you have already diagnosed the problem. as the safety switch itself or connection to the switch because of your prior experience with the failure.. I am also assuming that you have made sure that the PTO is turned off, and the cruise is off. I would think the switch is bad or the linkage is misadjusted to the switch. But that is based more on your prior experience than anything else.

yes it acts like it is in low med or high ie does not crank or any noise at all when in neutral .I suspect it is electronic..

I have checked all that you have mentioned.. except for cruise. I will switch the pto on and off to see if that works.
it is currently off

Sounds like the same problem I'm having with a DK40 SE HST. (NEW) I have to turn the key to the "Start" position several times to finally get it to make contact. A question to the dealer about any known problems with this model resulted in the shipment of a new ignition switch. I'll let you know what happens when I install it.

It does sound like a bad connection is preventing the transmission from either recognizing or going into neutral and it will not start if not in neutral. Does the N light light up on the instrument panel?

That would tell us a lot right there, if the N lamp was illuminated or not, if not then the problem is likely the safety switch on the hydro range lever, or its connection. If the N lamp is illuminated but still will not crank, then perhaps the notorious key switch.

yes the indicator lights al work I am wondering if the switch does?

Switch sounds likely to be the problem. Is your tractor kept outdoors in the rain? I haven't heard of a lot of DK ignition switch problems yet but the CK guys certainly have had their share and the key works in both!
