Hi from down under.
Somewhere on the web some kind person has possibly loaded a copy of your tractors manual. Best to supply model
and serial number.
I don't own a Carraro but I wish I did. I have a late 70's early 80's Valpadana 17hp constant 4WD pivot steer. I after years of getting replies from
Valpadana to contact my nearest dealer(who did not want to know or help me) I started searching the web. It took a while but I found a site in France that had the correct manual. FREE! Downloaded & printed off it told me more about the tractor than the local dealer ever did! Don't worry about the language most Italian manufacturers print them in a choice of 5 languages! #4 is English! Good luck with you search. Robert J I
