I use an International 574 for my ploughing, the lift arms are 750mms long and when I push the plough as far right as possible the front disc arm fouls the lift arm. I have been told to use longer arms to overcome the problem would this be the best solution or would it be better to lengthen the present arms by cutting at the cranked bit and welding 4 inchs on and welding the balls back on? Any comments would be gratefully received.
