Mower shuts off when blades are engaged or when you press the clutch for forward or reverse motion carb and gas tank have been cleaned with new fuel filter also

Take it out of reverse! My mower does the same thing. Put it in neutral, brake on and start the mower. The blades will engage. Put it in a forward gear and get to cuttin'. BUT, if you come to a stop and try to put it in reverse you'll kill the motor unless you disengage the blades first. I don't like it either. They say it's a safety thing.

If this is an older mower that has carburetor adjustments , turn the large needle valve counter clockwise 1/8 of a turn., and see if the mower runs with the deck engaged. If there are no adjustments on the carb. It may need need cleaning, and the gas filter may need to be changed. You can place 1/3 -1/2 can of carb & fuel system cleaner in the gas tank and run the mower. If this does not help, please forward info on the mower - Model #, serial #, and Model/ serial # of engine, which is usually on the ehgine shroud.

Sounds like a problem with the governor. Start it up. Don't engage the blades. Drive to a hill. Idle all the way down. Try driving up the hill. The motor should pick up when it slows while pulling up the hill. If it doesn't, the governor isn't working right.

Hi gedallyn,
You mentioned that every time you gear forward or reverse the Mower's motor will just die.
I believe that you will need to check your gears and the also check to see the if the system is Running low in Fuel or possibly having a clog in the fuel line that can cause the machine to stop.
But still the issue is when you get it to gear forward or reverse, you may wanna check the gears first since that is the closes to your concern.
You can also check online at Toro for a user guide and info regarding you issue with this Link
I hope this help.
Have a nice day,

Hello

Have a look at the saftey switches.theres one under the seat.and one under the blade engage lever.

There may also be one under the hood near the fuel tank.

your valves might be sticking due to old gas when you had some or the little rod clutch rod to the carb is disconnected this is just to choke it before it dies out.
I sugest that you clean out the carb out with carb cleaner and also clean the valves.

Hi..my name is Keith..and the newer mowers have all kinds of safety switches..and the mowers will shut off..if you put the mower in reverse with the blades on..so i would suspect you have a bad reverse safety switch..i hope this will help..if not please write me back

a couple other checks would be to dump the carb resevoir where the float is, water under the float could be accumulated and closing the fuel off, due to density. out here on the farm we never use the gas to the last drop from the can. also the linkage between the motor fan blade, (govenor) might have been connected to the carb incorrectly. or a bad switch interlock on the mower blade.
some briggs motors are hooked wrong straight from the factory, where the throttle linkage is concerned. ( and the little spring is pretty hokey too)

Did you try to disengage the safety feature that should shut the tractor off when the blades are engaged and the tractor is placed in reverse? I believe that it is located under the shift leaver

Did you drain the fuel before you put it away? If not then you should drain the fuel and clean the carb. Gas when in lawn mowers and any other small gas engine will turn into a slim in a way and will block the carb. Drain the fuel and clean the carb system will run great when that is done
