I have a craftsman lawn tractor model #917.273639, when I start it and put it in gear and release the brake pedal the mower shuts off. Is there a switch that needs to be replaced, if so what is the part # and where is it located?

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

This could be caused by not enough air getting into the system, not enough fuel getting into the system, or the fuel/air mix not burning well enough once it gets into the cylinder. It`s probably a clogged air filter. Could also be a clogged fuel filter or a bad spark plug.
Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

Clutch pedals in manual cars stay on the floor if there`s a failed clutch release bearing, slave cylinder, clutch master cylinder, or clutch linkage.
For instance, if a driver takes their foot off the clutch too quickly while stationary then the car will stall; taking the foot off the clutch slowly will stop this from happening. Stalling also happens when the driver forgets to depress the clutch and/or change to neutral while coming to a stop.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
If your lawn mower starts, runs for a while, then dies, check the ignition coil, gas cap, and spark plug. One or more of these parts could be causing your problem. Follow our repair and symptom guide to help you fix this.
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc.
Sticky or stuck pedal

A clutch that sticks can cause grinding noises or can keep your vehicle from going into gear while a clutch pedal that is stuck to the floor renders your vehicle undriveable. If either of these situations happens to you, a trip to your mechanic is in order.

Signs of a failure

You might notice that the clutch sticks, feels spongy, vibrates or the pedal is loose. There may be squeaking or grumbling noises when you press the pedal, or you might be able to rev the engine but have poor acceleration.

Stalling the engine in a manual car is NOT bad for the vehicle, so long as it`s not done 8 or 10 times every day.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
If either of them are failing, they can both whine or cause a rotational noise, and they put additional drag on the engine while the clutch pedal is pressed, potentially causing the stalling you are experiencing. In both cases, the transmission (or engine) must be removed to repair this.
A bad spark plug often causes an engine cylinder to misfire or sound like it`s struggling. The engine might even stall out completely while you are mowing. You may also notice that it becomes increasingly more difficult to restart the mower each time that it dies.

My husqvarna zero turn mower has an auto safety shut off. I have isolated 3 (Brake, Left control level, and Right contol lever)trying to see which one was faulty, but I’m not sure where to go next. When I took the brake off, the mower stalled so I held the safety button down and when the brake was off the engine stayed running. But when I pulled the Left or Right Control level to move, it shut off, so I held those down to see if I could see which one was faulty. The engine stayed running, so I couldn’t figure out which one was bad. Every thing stayed running until I engaged the mower deck, and then it shut down again. I gave up at that point and figured I needed an experts help! Thanks, Jon Sable
ANSWER : There should be a switch under the seat. The system is designed to stop all functions if no one is setting in the seat. I believe the seat switch has failed.
Check it out and let me know.

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

ANSWER : You most likely have a safety switch issue, try un-plugging the switch in question and holding the wire connectors together with a small vise grip and do a test to see if it will run. If it stays running, then replace the switch in question before using your machine.
