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.

ASABE Adopts ISO Standard for rear-mounted 3-point linkage.

Hi IceStationZebra, thanks for your reply, does the rolling radius change ssae the several configuration for a specific tractor? If the document is revised or amended, you will be notified by email. They could have chosen a distance that was farther back, but then the number would be smaller and infer less strength.

Close this window and log in. It would help a lot if you told me which country or countries you are interested asqe. There I created a tool to design a TPH.

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. I got the point. One example is taking production varience into account. Prospective users are responsible for protecting themselves against liability for infringement of patents. Farmers will add weight to the front of the tractor to offset the lack of stability. We have no document history for this standard.

Your Alert Profile lists the documents that will be monitored. I noticed all companies are set up to a similar lifting force for the same tractor type. Join your peers on the Ssae largest technical engineering professional community.

And then there are countries like the USA where 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 cases.

ASABE Technical Library :: Abstract

As asar compare specifications nobody wants to appear lacking. OK, you are talking about the tire rolling radius. The EU is a prime example. Some tractors have multiple holes for the top link, meant to increase the tipping action with long implements like plows. This is where homologation comes in.

It appears mainly so they could introduce the idea of adjustable lift rods.

I wouldn’t be surprised if they cut corners a little, but you would have to measure very carefully to find out. Which, like you pointed out can get silly.

Will you see different performance with a “quick hitch”? Please first log in with a verified email before subscribing to alerts. This will make customers think you have a weak tractor. They are usually fairly abrupt. Saae sounds weird to me, since it’s not a safe working condition. In this case it may have come from the Nebraska tractor test, but I don’t really know. Already Subscribed to this document. We have no amendments or corrections for this standard.


Therefore zsae normal working condition the lifting force is lower than the one measured with the OECD test. Do companies have to design a three point hitch in according to this standard or not?

I don’t understand one constraint called “mast adjustment height”, it isn’t drawn on the standard. Some aspects of homologation will be worse off with tall tires, others with short ones.

On the negative side this is stressful to the tractor structure, adds to soil compaction, and burns extra fuel. Would it be useful for designers to take into account to design a three point hitch? I guess you would probably use it on any implement that is nonsymetrical. Awae was wondering why just that lifting force was choiced by producers. The Eng-Tips staff will check this out and take appropriate action.
