Cub Cadet 3X30
Here are the pictures I took of your Pro XT 3575b skids on my Cub Cadet 3x 30 inch HD snow blower. They were taken with the blower inlet ramp set at 1.5 inches above the floor. Just behind the Pro XT 3575b skids can be seen the original Cub Cadet blue plastic skids. I made a print of the Blue Cub Cadet original skids which is also attached with the dimensions I measured using a digital caliper. It appears I can adjust the Pro XT 3575 skids to obtain an inlet ramp variation from about 1 inch to 2 inches from the ground without the use of spacers. This is just what I was looking for in skids.
