Does anyone out there have a 5 ft. Howse shredder..... .and do you know how to get the spinner and sling blades off the gearbox shaft? I got the castellated nut and cotterkey off the shaft with an impact wrench but it seems no amount of heating or pulling with a gear puller is going to pop the spinner hub from the shaft. Is the hub threaded onto the shaft.....is the hub keyed..... and/or does anybody have any good advice about how to get these parts seperated? Thanks in advance for any and all replies!!

Thanks for all the helpful suggestions gentlemen. The shaft is indeed finely splined....and once I knew there were no threads to mess up....with the aid of a really big hammer, the wedge idea, and armed with the sure and certain knowledge there was nothing to be damaged I was able to get the spinner off this evening. Numero Uno on my list for the autoparts store tomorrow..... anti-sieze compound!!! Thanks again everyone for your assistance....once again the board has paid off for me....thanks to y'all!

I just went out and looked at my howse and 2 things come to mind. 1. Leave the sling blades on the hub until you get it loose on the shaft. Like Ultradog says. There's a lot of leverage to be gained on the end of the blades prying down on each side of the hub. Maybe wedge some 2X4s between the blades and the deck to keep constant pressure on the hub, then,
2. My deck has a big access hole cut behind the gear box for access to the blade nuts. This could give a place to beat on the hub from the top as you keep the pressure on from the bottom with the puller and the wood wedges. The blades are bolted to big supports on the hub which would be a perfect place to put your drift and whack it with your big friendly hammer. Watch out when it comes loose, it's a heavy dog. Steve

It's been a couple of years since I've been under my 5" howse, and as I remember, it was just for the opposite reason. It was making one he77 of a racket and when I got around to investigate I found that the big nut on the gear shaft had come loose and the stump jumper hub was trying to slide off the shaft on it's own. If I remember correctly, the hub is splined, but not nearly as deeply as you'd think. Not like N rear hub. Mine was worn some from running too long with the nut loose and I had to get a big washer to take up the space so's I could tighten up the hub against the shaft. I tried to call Howse for a new hub, but was put on hold for so long I gave up and washered it up and it's worked fine. Wish I could be of more help. If I think of any more hints, I'lll jump back in. Good luck.

I don't have a Howse but my Bush Hog brand shredder can't be much different.
I would turn the entire machine upside down so you can more conviently work on it. Cut some wooden wedges out of pieces of 2X4 and force the spinner away from the body of the mower. Put the castellated nut back on upside down till it is flush with the top of the shaft then hit it a couple of times with a BFH. It is a tapered shaft with a large key in it. The secret is to use 3 or 4 wedges and get enough force with them to make the spinner pop loose.
Any time I take something like that apart I always reassemble it with anti sieze compound. Maskes it much easier for the next guy, which if you keep it long enough might be you.

Both the king kutter I used to have and the bush hog I have now have a hole in the deck so you can get a big socket in to take off the sling blades without having to remove the spinner.

thanks for the help and helpful suggestions. I have the shredder standing on its side and chained to a large oak tree so its pretty handy to get to now.....but I like the idea of a hole in the deck to get to the sling blades without having to dislodge the spinner. I am going to make one more run at getting the spinner off and if unsuccessful me and the cutting torch have a date with a deck plate..... .thanks a bunch!
