Machinery:
HSX 140, 2x 8111, CNH 895, MF50B. Heap of machinery.
I have a 1990 8111, I am restoring. It runs fine but it has a problem. When I start it, the PTO is running straight away. I have got the PTO pack rebuilt by a Zetor garage with all new parts, but that didn't solve it. I have done the test of check the oil coming out of the top and bottom pipes on the side and they are working correctly. The high torque is working fine. The only way to stop the PTO when the tractor is running is to put the handle on the floor into neutral. Is there any else to check? Would it be anything to do with the linkage on the top of the gearbox? It's not lose but would it be worth a look to check anything under the cover?
 
What oil pressure do you have with open and with closed pto clutch at the pto hydraulic pipe?
 
I haven't done this on an 8111 yet, only on a 9540 with a hydraulic PTO clutch.
But basically you need access to the oil pressure line, find or build an outlet to connect an oil pressure gauge and then monitor it while you let the machine warm up and repeatedly switch the PTO on and off.

The target pressures should be found in the repair manual .

If the target pressure is too high when the engine is off, I would first check or replace the valve for switching it on/off.

I have an original Zetor /ZTS transmission/hydraulics test case. I can see if I can find more information about it and take photos if necessary.

In my ZTS 8011 to 16045 workshop book I found also this:

I think that should be pretty much the same on an Zetor/ZTS 8111.

The only things you need is a hydraulic pressure gauge and a piece of hydraulic hose. I think hats all to test it like described. :unsure:
 
I think hats all to test it like described. Sorry don't understand this message?
 
To be honest, I don't understand your problem. The pressures are quite easy to measure, you don't need any expensive special tools - so why not do it?

Otherwise, I probably won't understand you if I'm wrong. ;)
 
Your a wealthy German man, I'm only a poor Irish farmer, I don't have that equipment you showed in that picture. I'm sure it would be expensive. I have a general tractor garage only 3 miles away, who would be able to do this and tell me if that's good or bad. It might all right for you to buy a fancy tools but It's not much use for me to buy special tools to use maybe once in my lifetime.
 
Your a wealthy German man, I'm only a poor Irish farmer,
That's nonsense, and I think you know that too. I had fewer tractors (and smaller ones) than you have and my little bit of meadow is probably also significantly smaller. So stop saying things like that, it's just uncool.
I don't have that equipment you showed in that picture.
... and I said that you don't really need that. A tester like this will do the job for under 30 euros

and a suitable hydraulic hose to connect it to your tractor.
The test case is great to have, but not absolutely necessary, especially since it contains much more than just the hydraulic test tool.

Hours of troubleshooting, possibly in a workshop, can be much more expensive. An hour in the workshop doesn't cost any less and after that you'll have a diagnosis but nothing more. After your own diagnosis you'd still have your own tools or you could sell them again.
That has absolutely nothing to do with being rich or poor, but rather with calculating and setting priorities.

My test case was actually a bargain on eBay years ago. I saw it by chance, together with an original wooden box full of special tools for Zetor tractors UR1 and UR2, and bought it for a mere 80 euros because hardly anyone else knew what it was. So it's not like you have to be rich to afford something like that, it's just a chance you took.
By the way, an hour in the workshop costs me between 60 and 120 euros in Germany - and you never know if and how quickly the error will be found and fixed. :eek: :rolleyes:🙈
 
Fair enough thanks for the advice I'll leave you the last word so. But I thought this was a forum, where many people can give their advice, but it seems to be a one man show.
 
This is a discussion forum. Why do you feel personally attacked so quickly even though I haven't done anything like that? Calm down please.

I only posted suggestions with affordable and easy-to-implement solutions and in return you call me a rich German because I bought a used test case for little money years ago?
The photo of the test case should only serve as an idea to show you what the test equipment looks like and make it easy for you to build something similar for your tractor.

I just wanted to help you with that.
 
Because your the only one answering my question eventhough you have never had hands experience of this problem before. It's great to get an answer so prompt but I would like someone who could tell me, they had this problem too and you need to look at ????

Many years ago when this website was a lively place every night, you could come on and there were many followers all on at the same time, we use to have craic and banter. Between a handful of people who work zetors everyday, all sizes all ages and you would get 3 or 4 answers to every question. Over time it was down to a handful of people.

A young woman joined this forum who was looking for advice on restoring a 12145. But she was also commenting on other posts on this forum as it appeared there was no longer anyone logging on anymore, with many questions were asked over a month and got no answers. She got a warning for not asking tractor related questions, as wanted to know how people day was., or what was the worst damage you ever did to a tractor etc. etc. And she never wrote here again. But one thing she said one time was when this forum when onto facebook, that people had stopped using this platform to ask questions was the beginning of the end.

I grew up on a farm, learned to drive a tractor at the age of 6 and had my first contact with a Zetor tractor at the age of 10 (Zetor 5211 from the LPG). Even as a child, I loved tinkering with technology with my grandfather (a farmer) and my father (a qualified agricultural engineer) and using it on our small field.
In 1992, I learned farming myself and in 2000, I got my master craftsman's certificate so that I could train apprentices on our farm, which had grown from 18 hectares to 700 hectares after the fall of the Berlin Wall, and one day run the farm myself. In the company, I always looked after and repaired our machines; we had our own small workshop.
As is often the case in life, many things turn out differently than planned - I became seriously ill in 2005 and had to go on dialysis but was still working in my parents' company. When I got my new kidney in 2012, I had to change a few things. I had time and founded Zetor-Forum.de to create a place for Zetor fans by Zetor fans, bought my first Zetor and started to completely overhaul it. I left my parents' company and began retraining as a programmer, which I later had to stop for health reasons.
After some back and forth, I founded my own small company in 2017 and have been selling Zetor spare parts ever since and also repairing Zetor tractors for friends from time to time.

It is now 2024 and I am almost 50 years old. I have now worked on a lot of Zetor tractors myself and have created and read a sizeable archive of documents and manuals for practically all Zetor tractors.

So I think that with the experience I have gained, I am halfway able to answer a question about a tractor that I have not yet had in the workshop, especially if the diagnosis from the Zetor Crystal to the 9540, for example, is almost identical.
But I fully accept it. If you want someone else to answer you, you can tell me nicely and I'll keep quiet. :) ;)

That must have been a long time ago, because I was registered in the old forum since 2012 and was online every now and then, and there wasn't much going on then. But Zetorworld.com always fascinated me, not least because it is one of the oldest Zetor forums and still contains a lot of knowledge. :)

OK, that's not nice to hear - but that must have been before my time here in the forum when Renze was still the sole admin.
Maybe @Renze would like to comment on that, I don't know.

But it is also a fact that there hasn't been anything like that since the forum was relaunched in September 2023 and structured a bit so that content is easier to find. Since then, there has been the Others category or the "Zetor general talks" subforum as areas for topics other than those specific to the model. You see, it is definitely welcome.

An example - when I asked you for your first name, it wasn't to annoy you, but because I just think it's more personal and nicer to address each other by your first name instead of a pseudonym. It wasn't about changing your user name, but about entering a first name or nickname in your profile.
You don't want to - that's OK too.

I've built in a membership card - the idea is to find people nearby or even just in your own language with whom you can then perhaps exchange ideas even better. This is of course voluntary and most people use it - just like you.

So we've not only brought the forum out of the Stone Age (software-wise) and into the modern age, we've also created additional opportunities.

And users are already adopting it more and more, the forum is growing again, slowly but it's growing.

And because you mentioned the community and the discussions - we've been organizing Zetor meetings since 2016. It was at one of these that I met Renze in person for the first time, as well as a Zetor friend from Denmark who we've been visiting every year since then. We're also trying to strengthen the community.

I don't want to deny that there's still plenty of room for improvement - you (and everyone else) are welcome to contribute constructively and productively.

Ok, but what exactly was the problem ? This is a Zetor forum, there was a category for unrelated posts, so people seeking for advice dont have to wade through a few feet of irrelevant posts. People always told me they appreciated Zetorworld being to the point, not muddied with irrelevance, but with some banter every now and then. It always has been that way. If people start messaging irrelevant info in WhatsApp groups instead of here on the forum, thats good. And if they feel insulted when asked nicely to stay on topic, well... the world is a tough place.

Over the time we've had several cliques come over from British farming forum, posting loads and loads of irrelevance that only meant something to guys who live in their town. They didnt come here at all to talk about Zetor tractors, so when asked to stay on topic, they went.

But one thing she said one time was when this forum when onto facebook, that people had stopped using this platform to ask questions was the beginning of the end.
It was the other way around: I put it on Facebook because the forum was severely flooded by Russian and Chinese spambots and people stopped reading every post because most were by spambots, for which the 20 year old forum software had no adequate protection.

And dont forget that in 20 years, lots of old members no longer drive Zetor.

I dont know why you are so bitter now, and ungrateful for the help you get. Do you want it or not ? Please lighten up a bit ! 😉👌
