Removed Mower deck. Bolts were rusted and had to soak bolts with penetrating lubricant. Bolt to one arm had loosen but did not hold brake arm. Had to remove assembly and finally removed bolt. Replaced self tapping bolt with new bolt and added 2 washers, lock washer and nut. After 2 hours completed project and mower works great

Nothing to it. easy as pie. Unbolt the old and throw in the new. Works like magic.
I should have taken pictures of the mower deck because I had a left over spring but I figured out where to put it. The diagrams in the owner's manual are not specific enough.
