creeping Mahindra bucket

[Spentit]

I have a 2016 2565 Mahindra cab model. Only 365 hrs and the bucket tends to creep down at an unusual pace. I know its a problem on tractors with high use but this thing is barely broke in. Its basically a rebadged TYM so this might be a problem others have seen. I have checked the obvious , leaks, sticky valve. But I know it could be a bad control valve. The 3 point hitch doesn't sag at all and the loader arms stay in place as well. Only the bucket is quick to lower itself. Any one else have this problem with a machine of this brand. Thanks in advance.

Have you checked with your dealer to see if they can get it covered under warranty? I know of a couple people who have had the problem before and Mahindra just replaced the valve.

Can you describe the issue you are having?

That is a good point. But my trust in dealers is minimal. I bought my tractor in a private sale so my only contact with my dealer is through parts. I got lots of parts fixin this tractor up through my local dealer but found I could get my parts faster, cheaper from the other side of the country. Odd yes but that's for another thread. I do think it is the valve. If I go through the dealer I have to deliver the tractor wait for a diagnosis, get warranty approval, wait for parts, wait for installation then the potential feud of who pays for what then truck it home. Not to mention the time of loss of use. I have a 84" snow blower on the back that is mighty handy this time of year. Don't see a "win,win" there. If the problem is the valve I will either rebuild or replace my self. I can do that in an afternoon.

Yes I can. With the tractor warmed up and running the bucket will dump it self. Does not need a load, just empty you can sit in the cab and watch the level indicator rod disappear into the tube. Or the other day I was working by standing in the bucket and in no time at all the bucket was so far out of level I could no longer stand in it to work. Kept having to continually climb out and level bucket. All within 15-20 minutes.

I see your in NH also. Which dealer do you use?

Sounds like a bad seal in the cylinder. Their was a good thread in the hydraulics section on this very issue.

Is this your issue? Sounds like it from what you have said...

So you think it is a bad cylinder seal. My logic would be that the two bucket cylinders are plumbed together and one cylinder would hold up the other. unless both are bad. But this would be a cheaper fix than a valve.

Just read the post you sent. Seems to make sense. I still think the other cylinder that is plumbed into the circuit would stop any flow unless they are both bad. I will plan on rebuilding both. Thank you for the knowledge.

I had a similar problem on my 2615HST. Mine was an internal leak in the loader valve. The loader started dropping about an inch per minute. I noticed when I was shoveling topsoil from the bucket that each time I turned around the bucket was lower. Luckily, it happened during the first year of ownership and was covered under warranty. My dealer told me it was the first one he had seen do that and agreed it was defective. He also said I was lucky to bring it in when I did because the loader valve only has a 1 year warranty.

Sorry but your logic is not valid in this case. The reason for this is the cylinders are connected in parallel where both rod ends are common and both cap ends are common.

This allows the oil leak from the rod end of both cylinders through the one bad seal to the cap ends of both cylinders.

Hopefully this explains what is happening.

Spentit, I’m not far down the road from Gilmanton. I’ll have the seals you need.

X2.......both cyls will creep out with one blown/worn seal.

That's good to hear. I will be waiting till warmer weather but will keep you in mind. Thanks.
