I had to adjust the width on my 530 ag tractor some time ago. loosened up the clamp and slide the wheel in and like a dummy hammered it tight with the impact. It cracked the saddle where it clamps to the axle. I tried welding it with some bluemax rod but it cracks right beside my weld. I cant see how that saddle even comes out of the hub. like a little puzzle. it has been cracked for about 5 years and looks to be getting worse.sort of stresses me out when I am roading the tractor and I think of that wheel coming off. anybody know where I can get an affordable replacement or if it crosses to the 630/430 tractors to broaden my search. I never see them on ebay. if I look up hub I seem to only see the utility tractor ones for fixed axles. thanks.
