How to Identify and Fix Common Gardening Problems ?

The traction control cable might be broken or misadjusted. Check the traction control cable to determine if it moves freely. If the control cable does not move freely, try squirting a small amount of oil into the end of the cable to lubricate it. If lubricating the traction control cable is not effective, replace it.
This can be as simple as the lawn mower having run out of fuel or battery, or in the case of electric mowers, the cable coming out of the socket. Also check cables, fuses and breakers for electric mowers. Trimming too much grass in one go can cause the lawn mower to get bogged down which will make it stop.
Most self propelled mowers utilize a solid shaft drive transfer system that turns the drive axle to both wheels simultaneously. If the drive loss is only in one wheel, the problem is likely a trapped, broken, or missing part within the drive ratchet or gear system of the non-functioning wheel.
So can you push a self-propelled lawnmower? You can push a self-propelled lawnmower, it won`t damage the transmission in any way. However, it may be difficult to do so, self propelled mowers are a little heavier than a regular push mower.
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.
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.
How Long Do Self-Propelled Lawn Mowers Last? A self-propelled mower should last eight years or more, depending on how often it`s used. (Most manufacturers rate their mowers for a set number of service hours.) There`s no significant difference in the service life of a self-propelled mower versus a standard push model.
Check the drive control cable when your lawn mower won`t move because the drive cable can stretch over time. Replace the control cable if it`s damaged. A worn or broken drive belt will also prevent the mower from moving so check the belt next. Adjust the drive belt or replace it if it`s broken.
They work by engaging a speed control lever (sometimes part of the handle; sometimes a separate bar or shifter) that causes the mower to move forward. The operator doesn`t have to push the mower, he or she simply walks behind it, guiding it around the yard. Self-propelled mowers can be front-, rear- or all-wheel drive.

Self propelled feature stopped functining. I previously replaced the wheels after the gears had worn down. Now I can’t get any response to engaging the self-propelled cable.
ANSWER : Have you checked the drive belt? There should be a belt running from the main shaft (above blade) out to the wheel drive. You didn’t list model number but I’m assuming it’s front wheel drive. There should be a cover over this belt so it might be hard to see from underneath. Also there should be a cover on top going to the drive transmission. If the belt is OK, check to be sure lever is moving the transmission lever.
