Toro Lawn Tractor won't start, engine turns

Have a Toro Lawn Tractor LX460, third season in use. Battery died 2 times while mowing. Jump started it once. Finally replaced battery, now it tries to start but doesn't. I spayed quick start in and it helps, there is gas in the fule tank and fuel lines but the gas is not kicking in. Could it be a spark plug or something with the carburator?

    We have fixed the problem. There was a sensor that turns the gas off to the engine after you shut off the mower to prevent backfiring. It was replaced and now it works great! Thanks for your interest in helping!!

    If the battery did die while mowing, the magneto is not generating current or, there is a faulty electrical connection from magneto or, there is a blown fuse in the magneto circuit. Could I get some additional info, please?: Why do you say the battery died while mowing? Why do you say the gas is not kicking in? What is the terminal voltage of the new battery now w/o engine running? What is battery terminal voltage with engine running? When you write that it tried to start, do you mean it cranks well but doesn't start or, that it cranks slowly? Could you describe what happens when you spray the carburetor? thanks... Charlie

SOURCE: Toro Lawn Mower Won't Start

this is a very common problem with these toro mowers. the needle valve in the bowl of the carb. is plugged up with dirt or varnish from the fuel. just under the primer bulb there is the carb bowl. it has a nut under it that holds it on remove the bowl and make sure fuel flows constantly while the bowl is off. push up on the float to stop the gas flow. this could be messy and dangerous. careful with the gas. its flammable. best solution is to remove the carb and soak it overnight in a parts cleaner like gunk. caution small parts inside. this happins every year on mine no matter what i do. seems like the orifice is so small it clogs easily. good luck

Carb. float must be stuck open. First if you have no fuel in the tank it must all be in the crankcase.Drain the oil and refill and also check the carb as the float has to be sticking open. Hope this will help you. Donnyb60

SOURCE: starts runs min. or two then stops....

Go to then click customer care, then click manuals and parts. Type in model no. and download the owners manual. This should get you the spark and flywheel gap. Probably still something in the carb. Some orifices are very hard to find and to clean but they must be clean. Also check for dirt dopper nest in the muffler.

SOURCE: Mower will not start. Makes a loud fast clicking noise when the key is turned.

Loud ticking usually indicates near dead battery, take it out and charge it. If it still ticks you may need to replace it as they are only good for a few years.

SOURCE: Toro TimeCutter z4200 will not start

Toro Timecutter Z4200 mounts gas tank under seat and below carburetor. After first started, Z4200 will start OK again during mowing this period. But after some time passes (next mowing), gas evaporates from carburetor. Can run down battery using battery/starter getting gas backup through carburetor to start engine. This is poor Toro design, but good for service charges when replacing good components while trying to fix this problem.
Better solution is to add an outboard motor one-way squeeze bulb (approx. $15) between the fuel filter and the carburetor. Using the squeeze bulb for first start will prime the motor so that it will start without having to crank so long (which Toro says will burn up the starter). Toro saves $15/mower as well as selling new Z4200 starters.

Changed filter, oil, full of gas checked gas flow everything is good , when I start m lawn mower it runs , when I engage my pto and start mowing for about 5 minutes it just quits

if this is got the 27 hp kohler engine, I know exactly whats wrong with it , due to grass and engine oil building up in a short time under cylinder heads , it actually makes a tight ball of grass and stuff there !! this holds the engine heat and ruins the ign module that's just above it there , I put two on in one season ( tractor runs 6-10 hrs day 6 days a week ) I finally gave up I bought a Kawasaki 27 hp twin and installed it , now its run for two seasons and no problems
engaging the pto has nothing to do with it , it would cut off if you just drove it around for 15 minutes

The battery in my JD lawn tractor was dead; it started and mowed several times with a jump start but eventually only the tractor would run while the mower would not engage. With a new battery installed,...

I suspect that the alternator/generator has gone bad, preventing the battery from chargine, or generating enough voltage to keep the electric pto on your mower engaged.

I think that it is located on the engine beneath the flywheel.

I hope this helps you.

I have not used my lawn tractor for a long time. now it just CLICKS when I try to start it.

battery does not have enough charge to spin the starter, you might be able to charge it up. try jump starting from a car battery then mow your whole lawn without stopping. if it restarts after that you are good to go, if not go to walmart and spend 25 bucks on a new battery. replace the gas first.

Batt dead jump start does not seem to charge

Sounds like a dead or shorted cell battery. Charging system is probably working but is showing overcharge since it is trying to charge a brick. Replace the battery and all should be well.

Hard to start lawn tractor

I have 2009 lawn tractor that will not start (from day 1) unless I use a small squirt
of start fluid into the air cleaner area. Nothing else seems to work. The battery will run down before it starts. Once engine is warm it starts great. Love the tractor,
hate the starting problem. Elevation is not a problem in michigan.
