Question about Craftsman 42 in. Deck 19.5hp Lawn Tractor
Could you have connected the battery cables wrong?
On most batteries, the + and - posts are marked with large markings. If you connected the battery backwards, that is, the plus (+) cable to ground (-) and the minus cable to the positive (+) post, it will never start. This will make the starter turn backwards, and the gear will not rise to meet the flywheel gear.---------------------Get the Starter Turning First. From your Description, it Sounds like the Clutch Safety Switch or the Blade Safety went Bad. 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 Jumper from Same Color Wire to Same Color Wire). Check the Clutch/Break 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. If these Check Good, then Use your Jumper Cable Set and Attach the Positive Lead Onto the Positive Post of the Battery. Now Firmly Touch the Large Post on the Starter. If the Starter Turns the Engine Properly, Then Check the Solenoid. Firmly Touch the Small Post at the Base of the Solenoid. If The Starter Does Not Turn and the Solenoid Clicks, Then the Solenoid is Bad. The manual recommends checking the following,
1) weak or dead battery;
2) corroded battery terminals;
3) faulty solenoid;
4) faulty starter;
5) loose or damaged wiring; ---------- If all checks out ok but still the same problem then, the pinion is stuck or locked on the helex on the top of the starter. Remove the starter,,,, Blow off the helex with compressed air, clean, but do not LUBRICATE! Move it up and down to see if it moves freely...if not,,,,replace the assembly.Also check the gear which engage on the flywheel if its cracked then it needs to be rebuilt.The cost of gear is near to $22.---------------- Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
