Yesterday, we got our first snow (late). It wasn't much, and was icy rain mixed in, so it was heavy stuff, maybe 3 inches. I was anxious to try the tractor. I still don't have a place to store it covered.

Someone at some point moved the original ignition to the top of the dash, right side, probably so they wouldn't keep shutting off the tractor with their knee.

I was stupid. I thought it through months ago, but forgot. I never covered the dash area. The ignition was frozen. It took some time, but i managed to get the thing warmed up enough to get the key in, and eventually to turn. However, when i did, the ignition was broken. Basically, the start position was the "on" position.

I went out and bought a universal ignition switch from a local auto parts store and began figuring it out. The original key appeared to have an "on" position and start, so i figured this would work. I dug through the manual to figure out wiring, and realized it wasn't going to be easy. Once wired up, the glow plugs stay on, since the universal switch keeps the accessory part on constantly. Once the tractor was warm, i decided to disconnect the glow circuit. The manual says that the tractor will activate the glow plugs if the coolant is low enough temperature, even in the "on" position. And, according to their diagram, the "on" position doesn't include the glow circuit. The tractor was already somewhat warm, so i couldn't test it with the glow wire disconnected.

So, tonight, i'm going to find out if this works. The glows will either work or not. If they don't, i see 2 choices. One is to put an inline switch in the glow circuit, so i can turn off the glow plugs once it's started. The other is to order another factory ignition switch.

What would you do? I have a feeling the bobcat ignition is unique. I'm not sure if the kioti switch will work. The bobcat switch has a nice factory connector (i wired the new switch to the old connector, to keep it intact). The kioti switch, on michigan iron, is like 66 bucks. The universal i got was like 10... I haven't yet called the bobcat dealer.

Thoughts?

Personally I would opt for the OEM switch. Just less hassle and you know it is right.

The OEM switch has "key to left, hold to activate" for manual glow plug. This may be what you are thinking is Accessory. If that wire was connect to "run" then glow plugs would be on constant. The auto glow plug is part of the timer relay and is activate through the main controller, no special/separate wire for the auto glow plug. When the auto glow plug is working you will see the glow plug indicator light come on for about 20 seconds then go off, the back on for another 15 - 20 seconds after engine start.

I do agree that the OEM switch is better option. Also get the option rain cover and the "tractor key". This key has tear drop shaped head so it does not stick out so far and catch you knee.

+1 on the OEM switch. Keep it original and not modified. I have the smaller tractor key mentioned and i like it much better.

My Ford tractor switch has a step just before ignition-on for the Thermostart. It's not a "glow plug" but it is a element that heats the air and fuel in the intake tube instead. These switches are cheap. If you can's see paying a premium for OEM, try that.

The positions are: Off Heat Ignition Start

Update:
With the glow wire, which is the "hold to activate" one, mentioned above disconnected, the glow plugs do turn on for 8 seconds in the on position. So far, this has worked.

I may leave it be for the winter, and fix it fully in the spring, since i don't want to remove the **** dash again.

As i mentioned above, a previous owner moved the switch from the original spot to on TOP of the dash, so there are no problems with hitting a knee. It's actually a really good spot. However, the rubber cover would be a huge benefit. Unfortunately, the switch i bought is slightly narrower in diameter, so the factory cover wouldnt work. For now, i'm covering the wheel and dash with a trash bag.

Winston1 - the switches in those pics don't look like the original. The original is made by Pollak. I'd hesitate to buy the kioti one, because i don't know if the harness plug is the same as Bobcat uses.

I'll call the dealer one of these days and order another oem and some more keys.

Thanks for all the help.

Kioti wiring harness and electrical is different than Bobcat - about the only major thing that is. The hard mechanical, engine chassis, hydraulics, is. Ditto on getting the correct OEM part. BTW have you looked at the old switch to see if you can re-set it to the proper orientation.

One thing I don't understand is moving the ignition switch. I have never hit mine with my knee. I believe the Koiti switch was mounted lower, thus could be hit. Seems strange, but then I am a short round guy that meets all of Obama's new ADA requirements....I am optically, folliclely and dimensionally challenged:D:thumbsup::confused2:

Happy New Year Everyone
