Question about Garden

1 Answer

MTD riding lawn mower will not start. Know for sure not the engine or the battery. When the clutch is depressed and ignition switch is turned no sound, nothing. Could the problem be in the Clutch Safety Switch? I have noticed in the past I had to push the clutch futher and futher to get it to start.

>>From your Description it Sounds like the Clutch/Brake Switch Bracket has Bent and the Safety Switch is Not being Moved enough to Activate this Switch.
>>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.
>>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 (Example: 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. Then Check the Oil Guard Switch (if Applicable). 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.**
>>Use a Multimeter and Check the Continuity of the Switch. The Meter should Show when the Contacts are Closed and Open. The Meter will Swing All the Way Over when the Switch Contacts are Closed and Swing Back to the Rest Point when the Switch Contacts are Open.
>>Send me the Model Numbers Off the Mower, Please. With these I can Locate the Proper Manual and Better Assist you. The Model Numbers are Usually Located Under the Seat on a Sticker or Tag on the Body.

No start

Check all battery connections... Follow the Positive cable (usually red) to the starter solenoid. Check connections. There should be at lease 3 wires attached to the solenoid, Battery cable IN, Battery cable OUT and a Smaller wire from the ignition switch. Test to see if you have power at the small wire when the ignition with(key) is turned to the START position. If there is no power, check the Seat kill switch and the clutch pedal switch. On most tractors, the clutch pedal has to be depressed to start the engine. If there IS power at the starter solenoid, check the Battery OUT cable. If there is power at this cable, check your starter. If there is no power at the Battery OUT cable, and there is power at the ignition wire, replace the starter solenoid. Hope this helps...

Ranch king riding lawn mower ignition problems check switch solenoid and battery now what?

If you have checked for spark at the plug end of the ignition lead and don't have one when cranking, the ignition coil has probably failed. Checking this part will require some disassembly of the mower and then the engine. I'm afraid these are all Chinese made coils now (cheap, cheap, cheap) and are common failures in most small engines.

I have a mtd riding mower that will not start and will not move just by depressing the do i move it

generally you are going to make sure the transmission is in neutral and the parking brake is not engaged. some have a parking brake, some don't. Those that do often have it as a tilt the clutch pedal forward when depressed engagement others have a specific lever or button. if you can not get the rear wheels to turn freely, you can put a floor jack under it and wheel it about with that.

I have a 2002 MTD lawn tractor, model # 13AF693G118, that will not crank. No click, nothing. As we have had this problem on and off sice it was given to us 3 yrs ago and have replaced the battery and the...

The Operator's Manual gives instructions for adjustments. You need to confirm that the lift lever and clutch pedal safety switches are being fully depressed. Also, there is a safety switch under the seat.

From your description of problem, try pulling the lift handle past the top notch of the index bracket with one hand and turning key with other and see if it starts. I had to do this with mine because the lift shaft assy is bent and required pulling farther to engage safety switch. You may need to replace the lift shaft assy ($50)

Hope this helps.

Craftsman riding lawn mower will not turn over.

Check to see if there are any safety switches on the seat that may have gone bad and aren't allowing for it to start. Also check the clutch. Some mowers require it to be depressed in order for the engine to turn over.

Either the igniton is bad or the wires are backwards. You can bypass the ignition and touch the wires together to see if the solenoid turns. You can also use an ohmmeter/voltmeter to check the current.

Engine starts, but stalls when clutch is released.

The is a safety switch located underneath the mower, in the dashboard area. This switch will not pass voltage to the ignition system unless the pedal is depressed, or the deck is not all the way up. However, your culprit is most likely the pto (power take off) switch on the dash that engages the blades. It will not allow the mower to start, if pulled, and if faulty will shut off ignition power when you release the pedal. First. You'll need a volunteer to sit on the mower and operate the controls.  Now put the deck down and with the pedal depressed start the engine. Nothing should happen, if it does replace the deck switch Sears part number #176138 mentioned above. Now raise the deck and release the pedal. Again, nothing should happen. Same solution if it does. If nothing happens on both tests the switch is ok. NOW. Behind the dash, find the pto switch, and squeeze the sides, depressing two clips that hold it in the dash. You should now be able to slide it though the dash, wiring attached. Unplug the switch. With pedal depressed, deck up, someone sitting on the seat, start the mower. Now release the pedal (making sure to block the wheels and have the transmission handle is in the neutral position. If the engine continues to run, you found the problem. Replace the PTO switch. Sears part number # 174651. Also, check the plug to the pto, ignition and deck switches for corrosion as this is a common problem, though not likely to cause yours, it could. Good luck, and please let us know the outcome, good or bad. Thanks so much.

Lawn Mower won't start

Its a thing of beauty to see problems solve themselves. It seems to me this trial and error approach is very taxing and could have been avoided if 1, your small engine repair guy/Craftsman/Sears had sold you the right parts from the start, or 2, you had bought the right part... from the start.
