YES ! Probably the drive belt.

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 reasons why mower is not moving forward or reverse is that the battery is dead, or due to clogged fuel line. Additionally, malfunctioning transmission, or a broken drive belt, also a faulty spark plug, even when friction wheel isn`t in contact with the friction plate, or damaged Tires.
If your lawn mower turns on but won`t move, there could be a number of potential causes. The most common issues include a broken or damaged belt, a clogged discharge chute, a broken or damaged drive cable, or a damaged or clogged transmission.
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.
Grinding gears, starting and stopping during operation, and the wheels not rotating with the pulley are common signs that your mower`s transmission is breaking down.
Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself. In the transmission section of your operator`s manual, you`ll find a section that covers oil viscosity.
The average residential mower is used for 1-2 hours per mow with 35 cuts per year. Based on that usage, a lower-quality line of residential mowers is expected to last 450-500 hours, while a John Deere residential lawn mower will last around 1,000-1,500 hours.
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.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

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.
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.

How do I know if the float level is correct on my 1981 5 hp Arriens?

The motor runs a couple of seconds when I introduce fuel thru the sparkplug hole, but will not start and run otherwise. Checking, fuel runs thru the line when I disconnect the fuel line from the carb. I removed the carb, inspecting to clean, and when I took the bowl I noticed it looked like the float is not in a level position. WAs stored with Stabil in it and somebody told me that that may have caused some problem but he was not clear what the problem would be.

ANSWER : Check air filter. Try to run without filter. If not, add gas through carb and see if she’ll fire. If she does,
clean the jet
