I have a 7499 Massey pulling a 750 j and m grain cart. The Massey has an 1 1/4 hitch pin but the j and m has a 1 1/2 hole size i believe. So there is alot of slop and when full can make you nervous. What is a solution here? I thought about upgrading drawbars, but it appears the next series up in agco has an 1 1/4 hole as well or actually its 30mm i believe.
