Hi troops,
I started to change the blades on my Scag Tiger Cub 48" deck today and ran into a problem. even with a 400FTLB impact wrench and the air compressor at max pressure, I couldn't remove the nut on the R/H blade bolt. I had to drill small holes progressively on opposite sides of the nut and took a chisel and hammer to split the nut to remove it. The blade on this spindle was in worse condition than the other two and I think that from striking rocks, roots, or other not easily moved objects, the bolt tightened excessively. I damaged the bolt in the process of drilling the nut to split it so I had to replace both. I have the nuts here in my parts stash but not the bolt, Scag dealer stocks them and told me that they are a common replacement part. I put a thin aircraft type washer under this nut in hopse that it will prevent what happened, time will tell!!!
I have to raise up this machine considerably in order to get the blade bolts to clear the bottom of the spindles and fall out. My hydraulic floor jack just makes it high enough as long as I add a piese of 2 by on the lift plate. Not crazy about that combination so I put my adjustable jack stands under the machine before I crawl under it.
