I have a John Deere Z445 zero turn mower and I can't get a wiring diagram anywhere. I called John Deere and they want to charge me. I am really in trouble because I need the mower for my business. I want to fix it myself but I don't have a diagram. Please help. If you can fax the 4 pages over to me or help me with another solution, please contact me. Thanks.

Hi,
Firstly that is not a commercial mower, though the engine is. Secondly, yes Deere wants to sell the service manal but the parts look-up is free. Just go to John Deere Home Page Redirect then Residential and choose Service and Support then Parts. Type in Z445 and there you have it.
That said there are two serial number breaks for the electrical system. I will attach the pictire of the harness used until 40000.
