Question about Craftsman 21 HP 42 in. Zero Turn Tractor Mower - CA Model
I have a Craftsman 21hp Zero turn with a 3 blade deck. It has the older deck height adjustment where you have to manually rotate the shaft located down on the right hand side. The previous owner said she had hit something and that a mobile Sears guy said that there was a broken "rod" underneath on the "deck assembly". She could still mow, but it would cut unevenly. Sure enough the left side cuts much shorter than the right. I have it up in the air and don't see any broken rods or broken anything for that matter. WHAT SHOULD I BE LOOKING FOR AND WHERE? Please help. Thankyou. P.S. I'll gladly pull off the deck and straighten or weld anything before buying a whole new deck assembly for over $400 ! Thanks again
U should get on flat surface an loosen guides bolts let it drop all the way down then tighten ur guide bolds an that should solve problem u can make sure none of ur pins are wore but they can usually ware almost all the way through and still not make it cut bad now before u adjust the deck check blade they have been known to cut bad if wore or bent

The problem you discribe is the classic broken blade spindle or quill. The tube that supports the bearings between the deck pulleys and the blades is almost certainly broken. Look under the deck [mower OFF] at the piece right above the blade that is malfunctioning and you will probably find a bad bearing or a chunk of the tube that holds the bearing/blade to be missing. That happens when the blade gets 'wacked'. The outer edge is cutting too high because the belt is pulling the shaft toward the center of the deck. The quills are fairly easy to replace. Get the model number off your tractor before you go to buy the part.
