Re: 47" Snowblower Driveshaft Issue
Just wanted to update this thread. After much hassle & research, I have my driveshaft problem solved. I knew the driveshaft I had was too long, but I didn't know why. I do now!
Apparently, if you use a 4X5 Quick-Hitch (BM17347) on an X7XX tractor, then you also need to use a 4X5 Implement Drive and Upstop Kit. (BM20871) I can't find any "official" documentation anywhere supporting this, but I have mine assembled and running with this driveshaft, so I know it's true.
First, my dealer ordered the X7XX Implement Drive & Upstop Kit (BM23236) for me, and that kit had the same length driveshaft that I already had. I think the PO of this equipment hodge-podged this package together, and his dealer sold him the wrong driveshaft the same way mine did to me.
I took it back and had them get me the 4X5 driveshaft kit. This driveshaft fits properly, and has plenty of slip-joint without bottoming out or binding or making the dreaded "noise" when you raise the blower all the way with the PTO engaged. I'm glad the problem is solved, just dissappointed that I had to figure it out for myself and that my dealer could not figure it out for me.
Pic1 below shows BM17347 (4X5) hitch with the BM23236 (X7XX) driveshaft. As you can see, there's less than an inch of slip joint left to fully compress the driveshaft. The blower is sitting on the ground in this picture.

I hope someone finds this info helpful.
