Hi Folks, '59 240 U International. Took my tractor out of mothballs from the winter. Checked all the Oils and fluids before starting up. Everything's up to snuff. Started right up, warmed up. Put it into gear and.... Left Rear wheel turns fine, Right side locked up... Thought it might be the brake plate locked up, so I disco'd the pedal and run the pad adjuster all the way out. nothing locked there. I'm stumped. I rebuilt this tractor from the ground up in 2002,and it's performed flawlessly until I guess when I parked it for the Winter in Nov. No issues when I turned the key off....Anybody have any ideas????
