Small Engines (Lawn Mowers, etc.): john deere z225 trouble starting, starter solenoid, jumper wire

Question
right after i finished mowing lawn my mower wouldnt start back up. i turned it off to clean it and when i tried turning it on it just made a loud buzz every time i turned the key.  a week later i replaced the spark plug and when i tried to start the battery was dead. i attached a charger and tried again but still only makes a loud buzzing sound.

Answer
Hello Tony:

Locate the Buzzing Noise for me, Please. Follow the Positive Battery Cable and Locate the Starter Solenoid. Whne you Turn the Key Does it CLick and Buzz. If No, then Listen to the Buzz and you should Locate the Relay. If the Relay is Buzzing, then Check the Safety Switches First Due to the Possibility 1 of the Safety Switches May have a Bad Connection or be Bad. This Relay will Buzz if the RH or LH Control Stick Safety Switches are Not Properly Engaged also. Are you Sure the Battery is Good and Does Not have a Bad Cell in it. Have it Load Tested. You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H... and Enter the Model Numbers Z225 and Click Find. Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. Select the Electrical File for your Model. The Following is an Instruction File for the Safety Switch System. Any Input is Appreciated. The Color Code of the Wires May be Different than those I Use as a Reference in the Instruction File. **PLEASE REMEMBER THAT THE INSTRUCTIONS FOR CHECKING THE SAFETY SWITCHES IS JUST THAT!!! FOR CHECKING ONLY. I NEVER Suggest a Mower be Operated with a Safety Device or Switch Disconnected or Bypassed. Now. On Some Model Mowers you can Simply Unplug the Safety Switch from the Harness. On Other Models you have to Place a Jumper Wire Between the Harness Terminals (on the 4 Post Switch (Clutch/Brake) Jumper from Same Color Wire white to White First and then Check for Fire, Now Include the Black to Black Wires if No Fire. Check the Clutch/Brake and the Blade/PTO Safety Switches First. Check the Seat Safety Last. Usually the Seat Safety is Not in the System for Starting the Engine. Just to Ensure Someone is in the Seat when Engaging the Transaxle and/or Blades. Use a Paper Clip or a Short Wire to Make a Jumper.** If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. I Hope you Had a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
