Hi  Shep53


thank you for you reply , that's now making more sense , so any pto shaft will fit the tractor end but i need to find out what type of connection the implement has.


i have just purchased a second hand flail mower for my tractor  which didn't come with a PTO shaft 


sorry if this was a stupid question I am new to using a tractor 


thanks again for you help

Most splined PTO shafts (and the shafts on implements) are standard size  1 and 3/8 inch. Some early tractors like the Fergie T20 had a smaller shaft 1 and 1/8th inch (I think).

You can buy adaptors on ebay (search for 'pto adaptor')

It also needs to be the correct length so that when the implement is lifted it does not fall apart and when it is lowered it does not become locked solid. Usually you adapt the nearest size with a hacksaw!

Most agricultural dealers should sort you out no problem.

Edit PTO shafts are also rated by power based on the HP of the PTO drive so Cat 4 is for more powerful kit than Cat 2.

thanks henchard

yes I know about getting the right length of PTO , according to the manual  the PTO is  1 and 3/8 inch so i think that's a standard size  which should make this easier

thanks again for your quick replies

Either tell your agri merchant or do some investigation , as many flail mowers can have  a slip-clutch or a break bolt in the shaft,so that any jams don't cause the shaft to twist
