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.

I wouldn’t be surprised if they cut corners a little, but you would have to zsae very carefully to find out. Join your peers on the Internet’s largest technical engineering professional community. Please first log in with a verified email before subscribing to alerts.

Taking into account the heaviest implementI get the same order of size of the maximum lifting force for a specific tractor size RE: By the way for the dynamic radius index I mean the radius that it is used exclusively for the calculation of forward ground speed during homologation procedures.

I got the point.

Please first verify your email before subscribing to alerts. Therefore in normal working condition the lifting force is lower than the one measured with the OECD test. I have another doubt regarding the three point hitch.

Some tractors have both and rpm PTO shafts, at slightly different heights. Click Here to join Eng-Tips and talk with other members!


But isn’t a tractor sold with only one front and rear radius index? Promoting, selling, recruiting, coursework and thesis posting is forbidden. Best regards Pietro RE: Your Alert Profile lists the documents that will be monitored. It would help a lot if you told me which country or countries you are interested in. I’m not suprised that similar tractors from different manufacturers have similar lifting forces. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

You also have to consider other options. Hi IceStationZebra, thanks for your reply. One has to realize that these standards are created by representatives from the companies who are selling these products, not independant engineers or scientists.

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

Will you see different performance with a “quick hitch”? I can aase you from experience that some things are very black and white while other aspects are not.

A few of the main ones are: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Taking into account the heaviest implementI get the same order of size of the maximum lifting force for a specific tractor size.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students asse their homework.

I saw that there is a reference to ISO If the document is revised or amended, you will be notified by email. It’s easy to join and it’s free. The geometry is designed to kick the rear of the implement up at the high lift range to facilitate transport of long implements i. But what I was really getting at is that to define adjustable lift rods you first have to define what a lift rod is. Students Click Here Join Us!


Sometimes the standards come from a group that already has a standardized process, maybe has done some comparative testing, and the others just agree to adopt it. They could have chosen a distance that was farther back, but then the number would be smaller and infer less strength. Thanks for your reply.

I have seen the test done with a bare tractor frame with no engine or tires bolted to the floor. Hi IceStationZebra, I was again on holiday. Do companies have to design a three point hitch in according to this standard or not?

As the voice of the U. Would it be useful for designers to take into account to design a three point hitch? It appears mainly so they could introduce the idea of adjustable lift rods.
