i know nothing about 3pt.system ... i only know 2pt fast hitch stuff...questions are what is standard top link length on bush hogs...how far are 3pt arms to there sockets from tractor.[an where to measure off tractor}reason for asking is i got some quick hitch 3pt prongs same as the ones on this web site an it just seems 2 miles long...drive shaft is stretched out there an top link measures 32 to 33inches,,cat 1 at tractor supply are 16in an wont ajust out that far...they had a 20in.cat 2...would that adjust that far..it was big hole,,so i didnt try it an then thought as i was driven home,, they probably had bushings for top link cause my top link attachment on tractor is 3/4 sm. hole.....bush hog is about 15in off back tires...thanks in advance...dewy
