Question about Snapper 7800785 - 2812524BVE 28" 12.5HP Hi-Vac Rear Engine Riding Mo

Snapper nearly dies when brake is released

Hi - new here. My church has a Snapper model 7800785 that has these symptoms. Cranks normally and runs great. When I am seated, trans in neutral, blade engaged or not, when releasing the brake, the engine RPM drops to nearly nothing but keeps running. If I rise from the seat, the engine will die completely. While the engine is running (although nearly stopped) I can engage the trans forward and reverse. When the brake is released the RPMs fall off to nearly nothing and the mower will lurch in that direction. Local dealer says the seat switch is good and they told me how to look at the connector and it looks good. Had a new fuel filter 2 months ago. I appreciate a suggestion. Thanks

Mower cranks and runs fine but when I release brake pedal, it dies. I have check all safety switches and they all have continuity when they are suppose to


Sounds like your seat switch isn't working. Operator presence (seat switch activated) is required when the brake is released & pro is engaged or your engine will shut down.

Why does snapper rideing lawn mower stall when brake is relased?


Hi Jerry:
These machines have a lot of safety switches intended to protect the operator.
If no-one is sitting on the seat (activating that switch), releasing the brake will shut the engine off.
That's the first thing I'd be checking.
Hope this helps.
Cheers.

Engine stalls when brake is released


Either you have a faulty ground, or safety switch is bad... unplug the seat switch...

I would say it's a carburetor issue but u say it runs fine except when you disengage the brake correct?

Normal performance 10 min of use then drags like brake on loses speedbrake assy gets hot unlock freewheel and pause relock will help run better for awhile


Hi, now there it could be one of two faults, the brake magnetic core is not releasing the brake after a period of time, it's breaking down , other-words it's dragging or the voltage from the controller is not high enough or not enough current , a controller fault...check the wiring going from the controller to the brake... now a simple test would be to remove the brake but still have it connected via the two wires and tape on to the motor now you must be careful here because the scooter will roll if near a incline etc...so you been warned !!!! ... does the scooter run okay now ?

I do repair brakes..

Car cranks fine, go's in gear fine but when i mesh gas paddle dies out when i release it go's back to normal idiling


Usually a sign of a faulty throttle position sensor or low fuel pressure.
Those two things would need to be checked first.

Riding mower dies when releasing brake


the seat switch is the problem. the switch itself could be bad, but usually theproblem is that the connector is just not plugged in all the way [by the way, trying to bypass the switch by inserting the wire doesn't work because there is a "switch" inside the connector to prevent you from doing just what you did]
