Loader work, Engine oil pressure warning, and engine dies...

[N7HEVN]

Hi all.
First time tractor owner, and only owned for one whole week now, so please forgive me if this is somewhat / or is fully, common knowledge.

I just took possession, one week ago, of my brand new MX5200. This is for a property that I've just purchased earlier this year. Most of the property has been cleared of trees, but I've found that there are some piles of dirt / rocks, that have piled around the trees that do remain.

Last weekend, all I did was mow and mow, and it was great.

This weekend, I started doing some loader work, trying to move some of that dirt / rocks that had been built-up around various trees.
As I went at the first tree, started to push the dirt / rocks (nothing crazy sized, maybe 30-40 pounds in there, at-most), the tractor kept revving-up and chugging, as I would be moving around, even with no-load on the loader. Then, it just kept dying, even stationary....
So, I gave up on that, and went to do some box blade work, and that was perfect.

This morning, went to do some loader work again, and just as I was completed with the little-bit of work I wanted to try, the tractor began to do the revving / chugging again.... So, now I'm really trying to figure out, is it me, and I'm doing something wrong, or is this just how the tractor will behave and I need to do things slower...?

I did a search for the dummy light "Engine oil pressure warning", and it appears many people have had issues like this, but didn't see anything that truly relates to what I've experienced.
Have an email into my sales guy, to see if he know of this, and will share that, if he has any enlightening information.

Thanks for your review!

Any chance you were leaning over the right side to see what you were doing? That could be the seat switch.

Make sure you are in the seat as mentioned. It is really easy to try and edge up or forward to get a better view of the bucket.

It wont bog down until you press the pedal to go forward or back and you are off the seat a bit. If you are completely stationary and just operating the FEL, it should still work as normal even if you are off the seat.

If this is definitely not it, call the dealer. Get them involved early, just in case.

Which model do you have?

Shuttle shift MX5200D
or
Hydrostatic MX5200HST

Ah....
Very interesting idea, regarding the seat sensor. Thank you for the quick replies.

I did not have my seat belt on, like I did when I was using the mower. So, that's an obvious difference.
Am not sure about how I may have been 'seated', but I honestly don't think I was 'moving around' on the seat.

As a comparison though, when I was using the box blade for hours, and working on the driveway, I was up / down from the seat constantly, raising / lowering the loader, filling it with lots of terrible ridiculous-sized rocks in the driveway (has not had any maintenance on it for years...) and the tractor never died or even chugged once, like it did persistently, when using the loader in the field, pushing the dirt / rocks around.

So, am very anxious to think / suspect that the seat-switch is the culprit, but it certainly is plausible.
You'll have to please bear with me, for getting back on-the-seat and troubleshooting further, as I only get up to the property about once a month.

It is the MX5200 HST.

Thanks again for the tips!

Another check you could make is to flip the seat up. It pivots on a rod. The rod is held in place with a clip. If you lose the clip the rod can wok its way out causing the seat to only be on the seat switch intermittently.

 

[North Idaho Wolfman]

What range were you in doing the loader work?

 

[N7HEVN]

Wolfman,
I was in Low, and had the RPM's around 1700-2000.
That's what I was curious about, which no one had yet replied / suggested, was what RPM range we should be in, when doing Loader work.
If anyone could advise on that, I'd appreciate it very much. Am such a noobie for this subject matter, and could be just causing my own issues...

 

[D2Cat]

N7HEVN, do you have an owner's manual? That might be good reading for someone with a new machine they are not familiar with. I'd have an HST at 2000 RPM doing loader work (as a guide). The RPM is what is pumping the fluid through the system. Too high of a gear, or no RPM under a load creates a "dog"! But don't go too fast for your skills, either.

Oh, welcome to the forum!!

I have an MX4800 HST, same exact machine as yours, except mine is a few horsepower and a turbo less.

I will say this tractor does seem to have an overly sensitive seat safety switch...I often lean to one side, and that's all it takes...tractor dies.

And just like Roadworthy mentioned, the seat pivot rod clip came off on mine, resulting in the rod sliding out and the seat dropping down. I ended up buying a similar small hitch pin rather than reorder the factory part and so far, so good.

The one other comment I'll make is that I've had the seat switch cut the engine out while doing all tasks...mowing, grading, loader work. So that may or may not be the issue in your case. I love my MX though...great machine. Mine is 1.5 years old now.

 

[North Idaho Wolfman]

Sorry little behind on knowing the MX options, but does it have either anti stall or auto throttle options?

Negative. It is an "economy" tractor; the only real luxury is the servo-controlled HST pedal.

 

[N7HEVN]

Thank you again everyone for the guidance and input.
I'll test this out in a few weeks, when I get back to the property, and try to remember to follow-up about all this.
I did look in the manual, but didn't find anything mentioned about RPM's and the loader... Of course all the typical, 'how to move the bucket', etc-etc, and pressure ratings, but nothing mentioning what RPM levels should be on the tractor.

 

[troverman]

There is no "correct" RPM level for loader work...that is something that becomes intuitive to the operator after a very short period of time. You can see that at idle, the tractor moves very slowly, the HST whines a lot, and the loader is very slow. So you know you aren't going to use idle speed. You can also see that at full throttle, the tractor moves quickly and so does the loader...probably a little too quick for precise work...and the engine is loud and is using max fuel. So while you could use full throttle for loader work, it probably isn't practical unless you are very smooth on the controls and needing to use every last pound of lift capacity. The answer lies somewhere in between. I like a smooth and fast loader, and smooth response of the tractor to HST inputs. Keep in mind with a heavy load on the front end, your power steering demand is higher too. I'd say generally speaking on the MX, I'm probably doing loader work on either side of 2000RPM.

Thank you everyone for your assistance on this issue.
I was able to make it up to the property this past weekend, and it does appear that the problem I had before, must have been due to the seat switch.
This time, I put on the seat belt, and did some loader work. No problems, no chugging, no engine stopping!
Lesson learned!

This is why I love these forums...learn something new all the time...at least if this happens to me ...I'll know to check that...thanks!
