HELP - transmission problem in new MF1840M

Folks. My MF1840M has only 100 hours. Hydrostatic drive (not shuttle)

Aside from loader Ram issues emerging in the first 50 hours (crowd rams not holding pressure, leading to oil leak which was traced to back seals not being installed in the factory !!!!), the most recent issue is the tractor occasionally failing to move when in gear. The 3 times this has happened, the tractor has been pointing downhill. Would not move in forward or reverse - in any of the 3 speeds.

When we towed it back on to the flat, it started operating.

We initially thought it was the gear selector electrical connections, as they are fly-by-wire. Confirmed that wasn't the case when the tech plugged it in (no fault codes).
They drained the oil and checked the transmission mesh filter - no apparently issues.

THEN - we went to put the oil back, there was a large amount of metal particulate in the base on the container that had come out of suspension. Some of these were 0.5mm in size, shiny, suggesting hardened material.

This is now in the hands on the dealer. Has anyone ever heard of this in such a new machine?
 
Welcome to the forum. Wish it was under better circumstances. It's at the dealer now, is the repair covered under warranty?
You said shiny - are they gold or silver in color?
If gold, it may indicate bushings or thrust washers are bad.
If silver, it could be worn gear teeth.
If black, it sounds like clutch wear.

Figuring they're going to have to tear into the transmission, it could be a pretty costly fix.
 
Hi there. My brother described it as shiney. I’ve insisted the dealer gets a full analysis done including large particle and metal type. There may have been yellow in there. Don’t know as yet. First suspicion from the colour seen is it hardened material.

by the way this oil was only 6 hours old from last change. Unusual that the dealer would change hydrostatic this early I realise but they did it at the 50 hour service and then left the filler cap off !!! The machine then ran some more hours until we noticed. So we insisted they drop the oil and get that tested as well. Fortunately it was fine.

Back to the main issue - how can this amount of metal material show up in oil only 6 hours old in a machine with <120 hours ? Also note - that oil was dropped cold ?not expecting any problems) so who knows how much of this material is still in the tranmission.

I would love to hear from other members , but my rough understanding is they would need to test the entire thing down. They couldn’t assume single source. Plus to get this material out of every nook cranny, cooking plus every seal would need to be replaced ?

At this point I want them to take it back for full refund. To my mind the resale value of any buyer checks the service record would be near zero. No-one would take on that risk which would far out run any warranty. . Interested in others thoughts and how I deal with the agent and agco themselves.

It sounds like it's the dealer's problem to identify and resolve.
Not sure of the laws in New Zealand, but here in the USA, we have what are called "lemon laws". Basically, if you got a "lemon" (it doesn't work right), you can insist on a refund of the item. Granted, you do have to allow them to resolve the issue a couple times but if it's still problematic, you get your money back.
If they fix the issue, I'd demand an extended warranty for this condition so if it happens again, it's on their dime (they have to fix it at no cost to you). If it repeats more than once, you get your money back for the entire tractor.
Good luck!
