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.
Clogged or Dirty Air Filters
Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.
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.
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.
One of the most common causes of a sputtering engine is an issue with the vehicle`s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine`s fuel injectors, and then pumps into the engine evenly.
Spark plug issues
The first one is a firing tip where a metal bends and creates a gap between metals and electrodes. Here the metal bends might have deteriorated, or electrode tips may be rounded off, thus, causing the mower to sputter.
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.
The most common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
(1) The blades should always be turned on at full throttle if the mower has a electric P.T.O. switch.
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.
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.
It may be a bad spindle bearing that is seizing up when you engage it which puts too much load on the engine and makes it die. You may hear some squealing sounds from the spindle and the belt may smoke.
The possible causes of a lawn mower blade spinning but not cutting grass include a damaged or wrongly installed blade, a dull blade, or damaged lawnmower tires. Other possible reasons can be improper tire pressure, a clogged deck, or a broken mower belt.
A loss of power is most apparent when you`re accelerating, and can be due to a number of reasons including air flow into the engine, fuel flow and even faults with the exhaust system.
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.

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.

The mower deck clutch cable broke so blades will not engage and lever is loose on my Sears Craftsman 42-inch lawn tractor (917-271-742). I fished out the top piece of the cable, about 12 inches down to a rusty point where it broke. If I get the clutch kit (175067), which includes the cable, spring, etc., can I replace it from the top, or do I need a lift to get to the mover deck from the bottom? I do not have a lift or ramp that would work. What would I need to remove to get to the location where the cable/spring assembly hooks up to engage the blades?
ANSWER : I just got the kit 175067. Have the old one off except for where it’s attached to the lever, schedule and weather has kept me from going further. Very simple to reconnect things at the pulley and above but not too sure how to connect the rest onto the lever and haven’t had a chance to get a good look at how the old one might be connected yet. Should be a simple fix.

MY CRAFTSMAN GT5000 WILL NOT ENGAGE BLADES USE TO MAKE A CLICK NOISE NOW NOTHING i HAVE POWER TO SWITCH & NOTHING GOING TO MOWER CLUTCH?
ANSWER : Sounds like the switch is bad. You can test the clutch by unplugging the electrical connector then grounding the black wire to tractor or directly to the negative battery cable then the gray one to the positive touch it then the clutch should click on. The switch can be found on Sears parts direct but you will need the model number under the seat. Starts with 917 then 6 more digits.Hope this helps, if so please vote yes. Thanks!!

Blades wont engage have 12 volts to the clutch when switch is pulled.
ANSWER : The clutch is electro magnetic, once 12 volts is sent throught the windings the clutch engages, so if it does not engage there is more than likley a brake in the internal windings which unfortunatley will mean a new clutch.

Garden tractor engine shuts off
ANSWER : Sounds like the operator present seat switch is not working. You can run the motor out of the seat, but not with the blades engaged. You didn’t list what model, but usually hte seat switch is connected to the negative side of the battery, and grounds out the magneto, so you can’t test it to ground. Put your tester on 12+ battery, and then to both sides of the seat switch. There is usually 4 terminals on seat switch. Some moodels have grey wires for the mageneto circuit, you can tell by whatever color also goes to the clutch switch too.
