in the users manual on page 16 is the installation of the mower deck shown - maybe you should check those steps

if you don't have it - here is a download adress - it was the first one i've found

Same thing here! Called Sears, and they sent a repair man. $99.00 for showing up. The bottom side of the PTO knob (?) electrically connects to a clutch, the wires were ripped in half!

There is a metal finger about 2" by 1/4" welded to the frame that keeps the clutch from engaging when not needed. It had broken off, allowing the clutch to free wheel, cutting the wires.

The fix: disconnect the engine, remove the clutch and reweld the finger. Or, buy a new frame ($$?), buy a new clutch, about $250, finish by putting it all together again, more $$ for labor.

I declined the estimate because I feel, by looking at the broken finger that this is a case of either poor work, or inferior material since there was no outside force, concrete, wood, etc. that could have caused this. I ran over nothing but grass. I feel Sears is totally responsible and should repair it at no cost.

We'll see how far I get.

Drive screw got wet and will need to be sprayed with WD-40 or Penetrating oil
