Why does my John Deere X739 Flash a Yellow Exclamation Mark?

[Gdarbo6844]

Hi everyone. I have used this forum before with great success and I appreciate what everyone does on here. Recently, I had a problem with my snow blower attachment and this forum's members made the right diagnosis and the problem was repaired. The snopw blower attachment woreks with no problems until now.

Recently, while using the tractor and snow blower, the snowblower will stop working (tines not turning) and a yellow indicator light comes on with an Exclamation Mark in it. When the snowblower stops working, I disengage the blower, wait a few seconds and reengage it but it still does not work, but the yellow Exclamation Mark continues to flash throughout the time. I have gone through my manual to figure out what this is but I cannot.

If I let the tractor rest for an hour or so, I can climb back and use the tractor and snowblower, but the snowblower stops working after 10 minutes and the yellow warning light comes on. Today, I decided to see what happens if I keep using the tractor and use the snowblower attachment as a snow plow (light fluffy snow today so no problem pushing the snow). After about 10 minutes of pushing snow, a Red Warning light came on that "Stop", so I knew I needed to stop.

I am thinking there is an engine problem, not a snowblower attachment problem (the hydraulics all work and the snowblower goes up and down with no problem). I checked under the tractor and there are no leaks. When I start up the tractor, though, it is very smoky and I can see suit settling on the snow next to the right side (as I am sitting in the tractor) of the tractor.

Any advice as to the problem? Thanks in advance.

Sounds like it is getting hot. Could be valves need adjusting or a head gasket. Have you checked the oil? Proper level? No antifreeze in it? Check radiator and make sure it is full of antifreeze Coolant. Pull the plugs and see if they are getting oil on them or fouled. Oil on plug you could have a busted ring. Is the smoke dark, blue, white? Does it smoke the whole time?

Don't know, but maybe a check with the dealer or a close look at the op manual will tell you. Good luck. I'd find out before blowing up the engine by keeping on running it.

Both good ideas. I called the dealer and I will get it into their shop on Monday. I suspect it is an engine problem as well. It sits idle until Monday. Fortunately, no real storm in the next few days.

I just bought a service manual for my X584. It details the procedure to pull the codes. Your dealer should be able to help you.

To be self sufficient, I highly recommend the Deere factory service manuals. They cost about 1 hour of my local shops labor time. Well worth the investment in my opinion. Even if you are still in warranty, having to manual to educate you prior to discussions with the dealer ensures it gets done right (disclaimer, I used to be a heavy equipment tech).

Thanks for the great advice!!

My diesel X740 would shut off the PTO when it overheated, self protection, I expect.

Check your air filter(s) inner and outer. It sounds like the snow is clogging your air filters. Yellow warning I am getting hot, Red I am hot. Diesel engines take huge amounts of air.

Addendum:

Also look in your owners manual and see if it has information on restricted or blocked intake air warnings.
