driveline categories

[jimg]

Ive searched the web as well as I can but still turned up nothing so....could someone point me to a source which describes each of the 8 categories of PTO/implement driveline types? Im not a member of the ASAE so couldnt look at the relavent docs there. Ultimately Im looking for a description of the correct driveline for a pull behind mower. Mfg pages list it as cat 5 but don't say anything about the type of joint. Would it be a CV?

Also a related question...what is the diff between pull behind (draw bar connection only) and semi mount?

Here's CCM's page on PTO shafts ... probably not as complete as you need but a start.
