Experienced gardeners share their insights in answering this question :
If you are sitting on the tractor seat and the engine stalls when engaging the PTO mover blades I would check the switch under the seat.
This seat has a saftey switch to assure that the operator is in a safe location before engaging the the blades. Also if the blades are engaged and the operator leaves the seat the blades will stop. If a young rider with insufficient weight the blades will not engage.
Hope this helps?
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 :
The pulleys in your lawn tractor are driven by the drive belt, and turn the spindles. If a pulley doesn`t spin freely, it can cause the engine to die when the blades are engaged. To check the pulleys for sticking and damage, first remove the drive belt from the engine pulley and lift the lever to engage the blades.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
You Lose Power in the Middle of Mowing:
Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
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.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
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.
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.
Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
Select first gear. Gently put pressure on the accelerator until revs reach around 1500. Slowly lift pressure from the clutch pedal until you find the biting point. When you are ready to release the handbrake, continue slowly lifting the clutch pedal and putting pressure on the accelerator.
A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
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.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
If the mowing deck is engaged and the unit is in reverse, the mower will shut down as part of a safety feature.

Mower cranks and runs smooth until i try to engage blades or put mower in gear. it then stalls out
ANSWER : The seat switch is not making. You can start the mower but if you try to move it or cut, the switch is acting as if there is no operator present. Find it under the seat.

I have a craftsman riding mower with a 27hp B&S engine. Have had sooo many problems with it. Now engine will crank but will not start. Have cleaned fuel line out and it just won’t fire. Any suggestions?
ANSWER : Some of the riding mowers has a safety switch under the seat so when you get off it shuts off. If it goes bad it will not start. check by bypassing the switch. For safety make sure it’s in neutral. This is a long shot . But it can be eliminated as a problem after being checked.

I would like to replace the mulching blades on my Sears Craftsman riding mower with regular cutting blades. I can find plenty of sources for new mulching blades, but not cutting blades. My mower is a model 917.259541 tractor and the blades currently on it are part #134149. I want to make sure I get the right size to replace them. Also, is there a source for a bagging system for this mower, that won’t cost as much as one from Sears?
ANSWER : The straight blade for the 42 inch mower is 138971.They cut better and are easier to sharpen and you will need them if you use a gass catcher. If you do not want to use sears for parts you may be able to find good deals on ebay.

I need to get the blade of the lawn mower sharpened.Any tips on how to disconnect the blade fropm the lawn mower?
ANSWER : There is a jig that you can buy that makes this job SO much eaiser. It is a universal jig that clamps onto the deck and keeps the blade from spinning so you can use a ratchet to remove the nut holding the blade on. One name brand is called a “Blade Hog”. You should be able to find one of these at one of the bog box hardware stores.
Hope this helps,
