Hi all, I’m designing a three points hitch and I know there is the ASAE S that imposes some geometric constraints. I don’t understand one.

What do you think about it? Farmers will add weight to the front of the tractor to offset the lack of stability. It’s easy to join and it’s free. It would help a lot if you told me which country or countries you are interested in. I got the point. Defense manufacturing is all about project manufacturing and project accounting. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Do companies have to design a three point hitch in according to this standard or not?

The Eng-Tips staff will check this out and take appropriate action. If the document is revised or amended, you will be notified by email.

I wouldn’t be surprised if there were a few tractors without, but the vast majority have had at least one adjustable rod.

There of course will be minute changes due to gross vehicle weight differences, but they will be minor. And then there are countries like the USA ssae standards may not be required by law, but if someone gets injured and you don’t follow the “voluntary” safety standards you will loose a lot of money in court ssae. This is where homologation comes in. This standard is also available to be included in Standards Subscriptions.

Appears that they are identical – so that doesn’t help. As customers compare specifications nobody wants to appear lacking. Please first log in with a verified email before subscribing to alerts.


Do you think it’s a good argument? Red Flag This Post Please let us know here why this post is inappropriate. Therefore in normal working condition the lifting force is lower than the one measured with the OECD s2117.

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Add to Alert PDF. Taking into account the heaviest implementI get the same order of size of the maximum lifting force for a specific tractor size RE: Why are three point hitch designed to develop so high lifting loads?

This sounds weird to me, since it’s not a safe working condition. You also have to consider other options. In this case it may have come from the Nebraska tractor test, but I don’t really know.

There are the “directives” that cover any machine sold in the EU. I saw that there is a reference to ISO You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Best regards Pietro RE: In the directive you have mentioned, any ISO standard isn’t mentioned about the three point hitch, but few companies in their tractor datasheet write the three point hitch category, so it should mean the most of them don’t follow any standard, right? This Standard sets forth requirements for the attachment of three-point hitch implements or equipment to the rear of agricultural wheel tractors by means of a three-point free-link in association with a power lift.

As the voice of the U.

About the w217 no number is put in the sales literature They could have chosen a distance that was farther back, but then the number would be smaller and infer less strength. I have never been involved with the homologation of a tractor, but my assumption is that you would have to take asa the worst case is for the size of tires offered. Your Alert Profile lists the documents that will be monitored.

You may delete a document from your Alert Profile at any time. I think somehow it’s the force necessary to lift the implement at a specific vertical acceleration. Will you see different performance with a “quick hitch”? I wouldn’t be surprised if they cut corners a little, but you would have to measure very carefully to find out. Hi IceStationZebra, thanks for your reply. I have never used it for any other reason.

I’m not suprised that similar tractors from different manufacturers have similar lifting forces. There are no stability limits in the testing so the tractor manufactures keep pushing the limit so they can claim to have the strongest tractor.

Though the difference axae small, what number gets put into the sales literature? Thanks IceStationZebra, I got it. Would it be useful for designers to take into account to design a three point hitch? Note that the “Mast adjustment height, lowest position” is the same as the “lower hitch point. Taking into account the heaviest implementI get s127 same order of size of the maximum lifting force for a specific tractor size.

I’m looking to nebraska test report of some tractors and I noticed the three point hitch can lift a load higher than the tractor stability limit. By the way for the dynamic radius index I mean the radius asar it is used exclusively for the calculation of forward ground speed during homologation procedures. Some tractors have multiple holes for the top link, meant to increase the tipping action with long implements like plows. There I created a tool to design a TPH.
