My good friend Don Olson sent me this question via email and thought it'd be a good one for the group discussion here...
" Do you know anyone who has an original 961 rowcrop tractor. I need to look at original rear lower lift arms. My parts book says part number nca 555-B (two) arms are unique to rowcrop tractors (except high clearance row crop). Roger said his gold tractor has 1 original and I aftermarket arm. He does not know why the 961 rowcrop has unique lift arms. Not a big deal but I would like to find out what the difference is , such as why they are different than 801 series or other models. "
