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.
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.
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.
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.
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.
One of the disadvantages of hydrostatic drives is that the majority of the oil stays in the loop and doesn`t return to the reservoir for cooling. One way to return some of the oil back to the tank is by using a hot oil shuttle valve.
Check the drive belt that is located just above the mower deck. Follow the belt as it wraps around the deck and to pulleys under the engine and the rear tires. Make sure the belt is secured to the pulleys, because if it is not, then the belt (and thus the mower) will not move. If the belt looks broken, replace it.
If you have a push mower with a power drive and try mowing backward without releasing the clutch, you could damage the mower. Even if you`re not using a self-propelled, mowing backward causes problems with grass discharge and leads to an irregular cut that neighbors will notice on your lawn.

ANSWER : Hello. IF your spark plugs are good, and your air filter is clean, and your fuel tank is not close to empty, the next thing to check is the fuel line and the fuel filter. As a general rule, I change the fuel filter every 40 hours and the fuel line every 200 hours. J.
