Left blade of the mowing deck hit a rock, bent the blad and cracked the madrel
Not knowing the extend of the damage I order all new parts to build an new housing (Mandrel) complete with shaft bearings and blade. Parts were exactly the same as original and fitted perfectly. Had a little trouble getting the old one off, had to break off the bolts that took some doing, but putting the new one together was a breeze. Tha

1) I removed the mower deck from the tractor had to unhook the clips and the lowering cable
2) I removed the upper pulley (used an impact and it came off easy)
3) I removed the blade(also used my impact wrench
4) Removed the mandrel
5) Ihad to weld repair the mower deck where it had split ( this is why the mandrel

6) I reinforced the bolt pattern with thick fender washers at the correct bolt pattern for the new mandrel and welded the washers in place
7) Ground off the welded areas to make them flush so the mandrel would not be in a bind when bolted back down
8) Repainted the deck before I installed all the new parts I ordered
9) Reinstalled the mower deck and adjusted the height to be level with the ground
10) Checked to make sure it worked correctly and went out and mowed the grass
11) All the parts were a perfect match to the ones I replaced and everything works as it should.
I work with my hands all the time and repair a lot of machines where I work. To me it was an easy fix prolly because of my experience. Your average homeowner might have a hard time fixing a mower deck if he or she doesn\'t have access to a welder which I needed in my situation. If there repair only requires a mandrel replacement because of a bad bearing it should be no problem for your average person to unbolt the broken pieces and replace them. Good luck and don\'t be afraid to get your hands dirty!

The deck pulley broke as did several bolts holding the mandrel assembly
I installed the new mandrel assembly and deck pulley then reinstalled the mower drive belts. The only difficulty was reattaching the tensioning spring. This required loosening of the tension adjustment bolt sufficiently to reattach the spring then retightening the bolt.

Lawn mower spindle was rounded off where the blade attaches. I had to order a complete spindle as well as the flange nut.
Removed the old flange nut by cutting it off with a reciprocating saw because the old spindle was rounded off where the blade attaches and I was unable to hold the spindle still while removing the flange nut. After I loosened the belt tension removal and replacement of the flange nut and spindle was very easy.
Take of blade. Remove nut on pulley. Take all four bolts off housing on top of deck. Screw in new bolts in new housing to make new threads. Install new housing. Secure all bolts. Install new pulley and blade and itGÇÖs done.
