Why does my john deere stall

Breaking in the engine seats piston rings and burns off residual oil that may have coated parts during assembly. The company also warns that the mower may consume oil during the break-in period.

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle. Tilted engine, as the most common reason for white smoke blowing out of your lawnmower no lawnmower should be tilted at an angle bigger than 15 degrees.

A lawn mower engine will puff out black smoke when the fuel and air mixture is too rich. If the mower is dropping out or not starting and you do notice the oil leak, you have a bad gasket. If the mower shuts off when you turn corners, but there is no oil leak, you may still have a bad gasket since the pressure to keep the combustion going is not strong enough. My John Deere z will crank on choke, but when taken off choke it dies instantly. Have any suggestions? How long has it sat there without usage?

These machines need to be cleaned and used pretty habitually, or else these things happen. Also sometimes parts are nto designed to go the distance. After cleaning all filters and lines, try it and see if it behaves better. Start by emptying out the gas tank, flushing the fule lines and carburetor, and cleaning out the fuel lines.

Dity gas will cause this issue and so will dirty spark plugs. Ask a Question Here are the questions asked by community members. Read on to see the answers provided by the ThriftyFun community or ask a new question. I have a John Deere lt tractor that runs great until I start to go up a hill then it stalls out. It is like it runs out of gas tank is full of gas and when I turn the tractor around to go down it fires right up and runs great. Any thoughts? It sounds like a fuel pump issue in the tractor.

Advertisement The pump is not pushing enough gas through the motor to keep the machine running. My John Deere mower starts and turns off quickly. I changed the filter and plug.

By Sylvia. This was the fix for me. When I opened the gas cap I could hear the air being sucked in. So the next time the mower started to stall I opened the gas cap at the engine picked right back up. Thanks for saving me so much time troubleshooting and possibly wasted money!

My John Deere starts for a few seconds then dies. I have changed the plugs, gas, air and gas filters, but no change. I can get it to crank successfully only by manually holding the start switch open for about 10 seconds. It runs great after that. If I turn it off for a few minutes, it will start again OK. But If I leave it over-night, the same problem returns. I don't like holding the starter switch on; afraid it may do some damage. Any thoughts on what cure may be? Hi, See if there is an idle screw on the carburetor.

If there is, turn it to see if this affects the gas flow. See if turning it clockwise will reduce the gas and turning the screw counterclockwise will increase the gas. Advertisement There are some other tips on this link. Water and dirt are enemies of a properly running engine. Should water enter the gas tank, it will choke the motor as it flows through the carburetor and into the cylinder.

Water gets in the tank through condensation, or through an ill-fitting gas tank cap. Dirt enters the system through the gas storage can, or accidentally when the tank cap is off. Dirt simply clogs fuel flow, resulting in an engine that sputters and stalls. Drain the gas tank, clean it and fill it with fresh gasoline. Dispose of the contaminated fuel properly. Replace the fuel filter, too, which could have absorbed too much dirt or water to be effective.

Check the gas tank cap. It should have a small vent hole on top that allows back pressure for proper fuel flow. If not resolved promptly, this issue can eventually lead to engine failure. Here is what can cause gas issues and how to solve them depending on the kind of engine your lawnmower boasts:. John Deere makes some 2-stroke push mowers. These engines do not possess an oil injection system, so they run on a premix of gas and oil, which is inserted directly in the engine.

If the gasoline used for the mix is old, it could have attracted water, which, in turn, can oxidize the fuel. I prefer to use ethanol-free gas which stores longer. Fuel Shelf Life Comparisons. If you notice your lawnmower overheating and the suddenly losing power, one of the possible causes is that the premix has gone bad. Since this prevents the engine from working correctly, empty the gas tank, fuel line, and proceed to flush the old gas out.

Try again with a newly blended premix. The oil enters separately. As long as there is enough oil in reserve, the issue almost always lies in the gasoline.

If you have used ethanol-based gas in your lawnmower that was sitting in your garden closet for over six months, it might have absorbed water. Ethanol can cause significant issues to a mower including malfunctioning in the engine and, if you left the old gas in the machine, even ruined the parts of the engine.
