QuestionI have a John Deere rider, LT155, Kohler 15HP engine.
To start it I must be seated, with the engine disengaged, and my foot all the way on the brake.
(Note on starting: it never starts if I follow the book, "if engine is cold" and move the throttle to choke poistion. I first do that, then while cranking I need to ove the throttle al the way to to the slow speed position. It then starts slowly, and after a short wait I can gradually move it to full speed.
It starts fine, but when I release the brake pedal, it stalls. The mower deck is still disengaged from the engine, so I''m thinking there is no additional strain on the engine when I release the foot brake.
I have put in new gas and replaced the fuel filter.
The only thing I also notice when I release the brake is that there is some movement of the choke linkage.
Also, if I fully engage the choke using the throttle lever, while its running fine with the foot brake on, it also stalls. Does the choke need adjustment? Anything to do with the carburetor? Spark plug?
Thanks,
Dan, Livonia MI
AnswerHello Dan:
Usually if the Seat Does Not have to be Occupied for the Engine to Start. Usually Only when the Blades or Brake/Clutch is Engaged. I Suggest you Check the Safety Switches. Check the Blade Safety First and then the Others for this Problem. The Following is an Instruction File for the Safety Switch System. **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.** 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 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. 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
Good Luck
