Having a Deutz Issue

[woodlandfarms]

So, it has happened again. I stalled out on a steep (say 30 degree slope) face down. Engine will not start.

if it follows pattern it will start after it cools down.

I hear the fuel rail activating (I think, at least I hear a solid click at the engine). So I am stumped. The only thing I have left is a low oil sensor and or oil temp sensor as a culprit.

I don't know Deutz well enough. I noticed that when I stalled the temp went up to over 200 on the meter. when I turned the key. But as I am at an odd angle it could be the oil being thin and a pressure sensor.

Stumped... any help?

Wow that is weird..
I never had that issue and I also have a deutz
What model is it?
And do you have any pictures

We will try to help you but me I'm stumped

Its a Deutz 4-1011F series engine. Oil cooled.

I can't find any schematic which shows how the PT Electric system works with the Deutz.

The starter/engine turns over?

Have you checked the kill lever which is back near the alternator?

Any chance it is a fuel issue? The opening gets blocked in the tank at 30 degrees when hot? That one is really a stretch.

I can not remember if we have a low oil shutdown or not - could be a bad one.

Might be worth a call to the deutz service center.

I am wondering if it could be the out of seat sensor? You might try jumpering it to see if it resolves the problem.

Well Carl, [ Woodlandfarms ], did you get it started? You might can bypass the oil temp and pressure, but only for a short time. Just enough to get it turned around and level, then check the oil level.

Well, happy (grumble) new year.

I think I found the culprit.

Backstory... I bought the PT from Ken who had it resurrected from an owner who for the most part parted the machine out. It's history is vague (correct me if I have this wrong Ken). The owner bought this 1850 and started a slope mowing service for the state. With under 200 hours the engine blew. The owner at the time got into it with PT and Deutz, and in the end was compensated with a new engine which he replaced. But the machine looks to have caught on fire from the starter relay. The motor cage (PT Hood) has a nasty weld spot there where the cage made contact with the positive side of the battery. I think after the engine went in the guys work slowed down (he had purchased a second 1850 which is Kens) and decided save money and use my PT as a donor machine for his active machine. So, Essentially I have many new items (like an engine and all sorts of fun stuff) mixed in with some really old items (the hoses and some of the wiring).

Now, here is where it gets interesting. My machine does not have either of the following. A seat pressure sensor (do any of the PT's have this?) nor does it have a high temp alarm. I believe that this high temp alarm is on the PT somewhere (anyone care to enlighten me?).

I got into the engine side panel where the electric goes. This area has always been suspect in my book. Too much electric tape and a couple of wires that do not make sense.

In looking at the machine today I think that what has happened is that the previous owner has cut the wires from the temp sensor with alarm feature and has hooked the alarm to the oil pressure sensor (the one that kills the engine).

I have to send this idea to Terry tomorrow, see what he thinks as I spoke to him today and he had no clue what was going on based on my description. Now with this idea in my head we will see what he says.

Oh yes, I did get it started. Went and watched TV with the wife for a couple of hours (walking up hill to the house from a friggin ravine through blackberries).

Then asked the wife to drive me back to the tractor on the quad. She looked at me like I was from mars (It is in the teens at night). I walked back down the ravine... Hopped on. Turned it over once. Nothing. Turned it over again and it caught immediately.

Went back to the house and complained I had been living in LA too darn long. Wyoming summers are 15 degrees and I should be more used to this.

Wow great to know it works


No more problems?
Maybe it was just a overheat and back to normal

Well, that would make perfect sense if it is how you think. Rather than having an alarm going off when the engine gets hot, it kills the engine. Kinda harsh on the operator, though. Good thing you weren't crossing a highway or something like that! :shocked:
