Hey guys have a question from Australia! I am looking at buy a new bar for next season. I have a challenger mt765D tractor I am wondering what is the biggest bar I can tow? I would prefer a 60ft bar on 10 inch spacings. Our soil type is heavier dirt with some sand areas. Tractor is on 18" tracks. There is an amazing Morris bar but is 70ft wife I don't know if I could tow it without slaving the tractor??
